Vitamin and mineral supplements from a bottle simply can’t match all the biologically active compounds teeming in a well-stocked pantry.

By focusing on the big picture, it’s easy to get plenty of the vitamins, minerals, and other micronutrients you need to keep you healthy and prevent disease. Here are some tips.

Fiber. It’s the part of plant foods that we can’t digest. Eating foods high in fiber helps reduce total and LDL (“bad”) cholesterol, improve blood sugar control, and prevent constipation. High-fiber foods also help with weight loss by making you feel full.

There are lots of high-fiber foods to choose from:

  • brown rice
  • bulgur (cracked wheat)
  • barley
  • oats
  • nuts
  • beans and lentils
  • apples
  • blueberries
  • carrots

Vitamins and minerals. Vitamins are organic substances found in plants and animals. Minerals are inorganic elements from the earth (soil and water). Both are essential for normal growth and optimal health.

Here’s a list of vitamins and minerals that are crucial for good health, plus the best food sources of each:

  • iron — meat, poultry, fish, and beans
  • vitamin A — carrots, sweet potatoes, spinach, kale
  • vitamin B12 — meat, poultry, fish
  • vitamin E — nuts, seeds, vegetable oils

Phytochemicals. Phytochemicals are chemicals made by plants. They are not essential to life, but they do have a positive effect on health. Diets rich in phytochemicals have been associated with a lower risk of chronic diseases, such as cancer and heart disease. They are found in fruits, vegetables, beans, and grains.

The following is a list of key phytochemicals, plus the best food sources of each.

  • flavonoids — blueberries, raspberries, strawberries, blackberries
  • carotenoids — orange vegetables such as carrots, sweet potatoes, and winter squash
  • lycopene — tomatoes
  • isoflavones — soy foods, such as soybeans (or edamame)
  • resveratrol — red grapes
  • catechins — teas

Be creative

Adding finely grated carrots or zucchini to pasta sauce, meat loaf, chili, or a stew is one way to get an extra serving of vegetables. Dip vegetables into hummus or another bean spread, some spiced yogurt, or even a bit of ranch dressing. Slather peanut butter on a banana or slices of apple. Try mashed avocado as a dip with diced tomatoes and onions, or as a sandwich spread, topped with spinach leaves, tomatoes, and a slice of cheese.

From fast food restaurants and delis exploding with high-calorie sandwiches to salad bars stocked with high fat and high sugar salad add-ons — lunchtime can be a minefield of temptation for those trying to eat a healthy and balanced diet.

But a healthful and enjoyable lunch can be done. These simple tips can help.

Your meal should include lean protein, whole-grain carbohydrates, and produce. Roughly half of your plate should be vegetables or fruit; one-quarter should be lean protein such as fish, chicken, turkey, tofu, beans, or low-fat cottage cheese; and one-quarter should be whole grains, such as one slice of whole-grain bread, or half a cup of brown rice, whole-wheat pasta, or quinoa. You might include a small amount of healthy fat, such as a tablespoon of oil-and-vinegar dressing on your salad.

Salad can be a good way to go, but you need to be careful. Regular salad dressings, cheeses, and mayonnaise-based salads (such as tuna, chicken, and egg salads) can contain unhealthy fats, hidden sugar, and salt. Not to mention lots of calories. Here’s the trick to a healthy and satisfying lunch salad.

Step 1: Build a vegetable base. Load your plate with leafy greens and raw or grilled vegetables.

Step 2: Add some protein — a few scoops of garbanzo or kidney beans. Beans are an excellent source of fiber — and they’re filling! Other good selections include grilled chicken, low-fat cottage cheese, or chopped eggs. Go light on the cheese. A sprinkle of a strongly flavored cheese like feta or Parmesan can deliver flavor with fewer calories.

Step 3: Add a small amount of healthy fat. Sprinkle on the nuts and seeds. They are high in heart-healthy unsaturated fat and healthy protein, give you a feeling of fullness, and help food stay in your stomach longer. You might also opt for a dash of oil and vinegar.

Step 4: Whole grains and fruit make a nice addition to a creative salad. Look for whole grains like barley or bulgur wheat to sprinkle on top. Or add a few slices of fruit.

Our bodies can obtain vitamin D from diet and make it from sun exposure. Even with these two routes for obtaining vitamin D, however, inadequate vitamin D is common, and deficiencies can be found on all continents, in all ethnic groups, and across all ages—a major concern, given the many ways that vitamin D helps protect our health. (1) There are a number of factors that increase the risk of having inadequate vitamin D, among them, lifestyle, sunscreen use, geographic location, skin tone, age, and body weight.
  • Lifestyle: People who spend less time outdoors, or who cover up with clothing when they are outdoors, get less exposure to the sun, so they make less vitamin D. (1)
  • Sunscreen Use: Correctly-applied sunscreen blocks the harmful ultraviolet B rays that cause skin cancer, but it also blocks most of the skin’s production of vitamin D. So people who use sunscreen daily are more likely to be low in vitamin D. (1) But don’t ditch the sunscreen: The American Academy of Dermatologists says that sunlight exposure to unprotected skin increases the risk of skin cancer, and that there’s no safe level of sunlight exposure that allows you to make vitamin D without increasing skin cancer risk. Their advice? Use sunscreen or other sun protection daily, skip the tanning booths, and get your vitamin D from diet or supplements. (2) Some Vitamin D experts take issue with the American Academy of Dermatologists’ hard line on sun exposure, and they recommend a more moderate option: Put sunscreen on your face, and allow your arms and legs to get a small amount of unprotected sun exposure—say, 15 minutes max—before applying sunscreen or covering up. It’s still a matter of scientific debate.
  • Geographic Location and Season: In the summer, if you sat out in a bathing suit on a sunny afternoon for long enough to turn your skin slightly pink, you could make plenty of vitamin D. Yet during the late autumn and winter, people who live at higher latitudes produce little or no vitamin D from the sun, because the sun is at too low an angle in the sky. In the northern hemisphere, people who live in Boston (U.S.), Edmonton (Canada), and Bergen (Norway) can’t make enough vitamin D from the sun for 4, 5, and 6 months out of the year. (3) In the southern hemisphere, residents of Buenos Aires (Argentina) and Cape Town (South Africa) can make far less vitamin D from the sun during their winter months (June through August) than they can during their spring and summer. (3) The body stores vitamin D from summer sun exposure, but it must last for many months. By late winter, many people in these higher-latitude locales are deficient. (1)
  • Skin Tone: People who have a darker skin tone have more melanin in their skin, and this pigment is a “natural sunscreen” that slows down skin production of vitamin D. (3)  This the main reason why African Americans are more likely to be low in vitamin D. (4)
  • Age: The ability to make vitamin D in the skin drops as we age, and is one of the reasons why older individuals are more likely to have low vitamin D levels. (1)
  • Body Weight: People with excess body fat have lower vitamin D levels, so those who are overweight or obese have a higher risk of having inadequate vitamin D.  (1, 5, 6)

The bottom line: Low vitamin D can be found in all ethnic and age groups, around the world, for a host of reasons. Even if you are taking a standard multiple vitamin, the amount of vitamin D in most vitamins (400 IU) is not enough to prevent low blood levels. If you suspect that you are at risk of vitamin D deficiency, you can ask your physician to order a blood test for vitamin D.

Legumes play an important role in traditional diets in many parts of the world. They are low in fat, are good sources of protein and fiber, and contain a variety of micronutrients and phytoestrogens (plant estrogens). Phytoestrogens have received a lot of attention for their ability to fight not only cancer, but also heart disease and osteoporosis. They help balance hormones in the body and thus are thought to be particularly valuable for the hormone-dependent cancers: breast cancer and prostate cancer. It is well known that male hormones play a role in prostate cancer development.

Despite their advantages, legumes play a minor role in most Western diets. The typical Western based diet (lower in vegetables and legumes and higher in animal-based foods) can cause an increase in both male and female hormones (androgens and estrogens), while a plant-based diet tends to lower these hormones. This is the basis for the role of diet in the development of hormone-dependent cancers.

Soy foods, such as tofu, soy milk, soy beans, and vegetarian burgers, seem to be particularly rich in cancer-fighting properties. This is at least partially due to a form of phytoestrogen, called isoflavones, that is found primarily in soy. It appears to help prevent prostate cancer by binding to male hormone receptors in the prostate, thus reducing the stimulating effect of male hormones on prostate cell growth.

Epidemiological studies have shown that high levels of isoflavones are often associated with low rates of breast, colon, and prostate cancer. This has been used to explain why countries such as Japan and China that typically consume large amounts of soy have lower risks of these diseases.

The difficulty with consuming soy for reducing risk of prostate cancer is the lack of clinical trial evidence to support its use. As with any dietary component, it is difficult to isolate the effect of a particular food type to prove its effectiveness. One prospective study, including over 12,000 men, did evaluate consumption of soy milk. It found that those who drank soy milk regularly had a reduced risk of prostate cancer. The relationship held up after other factors were controlled for. Other studies need to be done to further establish the benefits of soy. In the meantime, getting more soy foods into your diet can be healthy for many reasons, and lowering your risk of prostate cancer may be one of these.

The prostate gland depends on testosterone for growth and development. Prostate cells, both noncancer and cancer, do too. This is why prostate cancer is sometimes referred to as a hormone-dependent cancer. Higher levels of circulating testosterone lead to higher concentrations in the prostate, and this appears to increase the risk of clinically significant prostate cancer. However, higher testosterone levels are not consistently found in prostate cancer patients, so there is more to the relationship.

A possible protective role of exercise has been proposed based on its ability to lower testosterone levels and to boost the immune system. Exercise causes a temporary reduction in testosterone, so regular exercise can reduce long-term exposure to testosterone. And chronic exercise has been shown to increase the number and activity of natural killer cells, which are part of the immune system that attack cancer cells.

Based on these effects, it seems that exercise should be beneficial, but the evidence concerning the impact of exercise on prostate cancer risk is inconclusive. In a review of 17 epidemiological studies of varying quality, 9 showed a beneficial effect, 5 no effect, and the other 3 actually showed an increased risk related to exercise or physical activity. None of the studies, however, provided conclusive proof, but taken together, they seem to support a weak beneficial effect of regular exercise on prostate cancer risk.

The challenge is proving that men who exercise regularly develop less prostate cancer when all other factors are the same. This requires a prospective long-term randomized study, and this probably will never be done. The best long-term prospective studies that looked at habitual physical activity in adulthood are encouraging, however.

A study of nearly 18,000 alumni of Harvard University showed that those who maintained a high level of physical activity were about half as likely to develop prostate cancer after the age of 70 as those who were least active. Another prospective study evaluated the level of physical fitness, as well as physical activity, on the risk of prostate cancer. Higher fitness levels were associated with lower risk in men under 60, but not in older men. And men who expended more than 1,000 kcal per week in exercise had lower risk than those who did not get this much exercise. The best long-term study of men's health is the Health Professionals Follow-up Study. It began in 1986 and has followed over 47,000 men in various health occupations since then. Data was collected in the beginning, and periodically through the study, on many factors including physical activity. The only positive result through 1994 was that at least 3 hours per week of vigorous physical activity was associated with a reduced risk of metastatic prostate cancer. But no relationship was observed between physical activity and the incidence of total or advanced prostate cancer. The same study, however, found an inverse relation between physical activity and BPH, more activity meant a lower likelihood of urinary symptoms or surgery for BPH. Walking 2–3 hours per week was enough to lower the risk of BPH.

The bottom line is that questions remain about the relation between exercise and prostate cancer, but there is no question that regular exercise is good for general health. So, it is wise to get some moderate exercise on most days of the week, and you may be protecting yourself from prostate problems, too.

Vitamin D Deficiency: A Global Concern

If you live north of the line connecting San Francisco to Philadelphia and Athens to Beijing, odds are that you don’t get enough vitamin D. The same holds true if you don’t get outside for at least a 15-minute daily walk in the sun. African-Americans and others with dark skin, as well as older individuals, tend to have much lower levels of vitamin D, as do people who are overweight or obese.

Worldwide, an estimated 1 billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups. (1-3)  Indeed, in industrialized countries, doctors are even seeing the resurgence of rickets, the bone-weakening disease that had been largely eradicated through vitamin D fortification. (4-6)

Why are these widespread vitamin D deficiencies of such great concern? Because research conducted over the past decade suggests that vitamin D plays a much broader disease-fighting role than once thought.

Being “D-ficient” may increase the risk of a host of chronic diseases, such as osteoporosis, heart disease, some cancers, and multiple sclerosis, as well as infectious diseases, such as tuberculosis and even the seasonal flu.

Currently, there’s scientific debate about how much vitamin D people need each day. The Institute of Medicine, in a long-awaited report released on November 30, 2010 recommends tripling the daily vitamin D intake for children and adults in the U.S. and Canada, to 600 IU per day. (7) The report also recognized the safety of vitamin D by increasing the upper limit from 2,000 to 4,000 IU per day, and acknowledged that even at 4,000 IU per day, there was no good evidence of harm. The new guidelines, however, are overly conservative about the recommended intake, and they do not give enough weight to some of the latest science on vitamin D and health. For bone health and chronic disease prevention, many people are likely to need more vitamin D than even these new government guidelines recommend.

Vitamin D Sources and Function

Vitamin D is both a nutrient we eat and a hormone our bodies make. Few foods are naturally rich in vitamin D, so the biggest dietary sources of vitamin D are fortified foods and vitamin supplements. Good sources include dairy products and breakfast cereals (both of which are fortified with vitamin D), and fatty fish such as salmon and tuna.

For most people, the best way to get enough vitamin D is taking a supplement, but the level in most multivitamins (400 IU) is too low. Encouragingly, some manufacturers have begun adding 800 or 1,000 IU of vitamin D to their standard multivitamin preparations. If the multivitamin you take does not have 1,000 IU of vitamin D, you may want to consider adding a separate vitamin D supplement, especially if you don’t spend much time in the sun. Talk to your healthcare provider.

Two forms of vitamin D are used in supplements: vitamin D2 (“ergocalciferol,” or pre-vitamin D) and vitamin D3 (“cholecalciferol”). Vitamin D3 is chemically indistinguishable from the form of vitamin D produced in the body.

The body also manufactures vitamin D from cholesterol, through a process triggered by the action of sunlight on skin, hence its nickname, “the sunshine vitamin.”  Yet some people do not make enough vitamin D from the sun, among them, people who have a darker skin tone, who are overweight, who are older, and who cover up when they are in the sun. (1)

Correctly applied sunscreen reduces our ability to absorb vitamin D by more than 90 percent. (8) And not all sunlight is created equal: The sun’s ultraviolet B (UVB) rays—the so-called “tanning” rays, and the rays that trigger the skin to produce vitamin D—are stronger near the equator and weaker at higher latitudes. So in the fall and winter, people who live at higher latitudes (in the northern U.S. and Europe, for example) can’t make much if any vitamin D from the sun. (8)

Vitamin D helps ensure that the body absorbs and retains calcium and phosphorus, both critical for building bone. Laboratory studies show that vitamin D can reduce cancer cell growth and plays a critical role in controlling infections. Many of the body’s organs and tissues have receptors for vitamin D, and scientists are still teasing out its other possible functions.

New Vitamin D Research: Beyond Building Bones

Several promising areas of vitamin D research look far beyond vitamin D’s role in building bones. And, as you might expect, the news media release a flurry of reports every time another study links vitamin D to some new ailment. These reports can be confusing, however, because some studies are stronger than others, and any report needs to be interpreted in the light of all other evidence. More answers may come from randomized trials, such as the VITamin D and OmegA-3 TriaL (VITAL), which will enroll 20,000 healthy men and women to see if taking 2,000 IU of vitamin D or 1,000 mg of fish oil daily lowers the risk of cancer, heart disease, and stroke.

Here, we provide an overview of some of the more promising areas of vitamin D research, highlighting the complex role of vitamin D in disease prevention—and the many unanswered questions that remain.

Vitamin D and Bone and Muscle Strength

Several studies link low vitamin D levels with an increased risk of fractures in older adults, and they suggest that vitamin D supplementation may prevent such fractures—as long as it is taken in a high enough dose. (9-13)

A summary of the evidence comes from a combined analysis of 12 fracture prevention trials that included more than 40,000 elderly people, most of them women. Researchers found that high intakes of vitamin D supplements—of about 800 IU per day—reduced hip and non-spine fractures by 20 percent, while lower intakes (400 IU or less) failed to offer any fracture prevention benefit. (13)

Vitamin D may also help increase muscle strength, which in turn helps to prevent falls, a common problem that leads to substantial disability and death in older people. (14-16)  Once again, vitamin D dose matters: A combined analysis of multiple studies found that taking 700 to 1,000 IU of vitamin D per day lowered the risk of falls by 19 percent, but taking 200 to 600 IU per day did not offer any such protection. (17)

A recent vitamin D trial drew headlines for its unexpected finding that a very high dose of vitamin D increased fracture and fall risk in older women. (18) The trial’s vitamin D dose—500,000 IU taken in a once-a-year pill—was much higher than previously tested in an annual regimen. After up to 5 years of treatment, women in the vitamin D group had a 15 percent higher fall risk and a 26 percent higher fracture risk than women who received the placebo.

It’s possible that giving the vitamin D in one large dose, rather than in several doses spread throughout the year, led to the increased risk. (18) The study authors note that only one other study—also a high-dose, once-a-year regimen—found vitamin D to increase fracture risk; no other studies have found vitamin D to increase the risk of falls. Furthermore, there’s strong evidence that more moderate doses of vitamin D taken daily or weekly protect against fractures and falls—and are safe.

So what is the significance of this study for people who want to take vitamin D supplements? A reasonable conclusion would be to continue taking moderate doses of vitamin D regularly, since these have a strong safety record, but to avoid extremely high single doses. This recent finding does present a challenge to scientists who will work to understand why the extreme single dose appears to have adverse effects.

Vitamin D and Heart Disease

The heart is basically a large muscle, and like skeletal muscle, it has receptors for vitamin D. (19) So perhaps it’s no surprise that studies are finding vitamin D deficiency may be linked to heart disease. The Health Professional Follow-Up Study checked the vitamin D blood levels in nearly 50,000 men who were healthy, and then followed them for 10 years. (20) They found that men who were deficient in vitamin D were twice as likely to have a heart attack as men who had adequate levels of vitamin D. Other studies have found that low vitamin D levels were associated with higher risk of heart failure, sudden cardiac death, stroke, overall cardiovascular disease, and cardiovascular death. (21-24) How exactly might vitamin D help prevent heart disease? There’s evidence that vitamin D plays a role in controlling blood pressure and preventing artery damage, and this may explain these findings. (25) Still, more research is needed before we can be confident of these benefits.

Vitamin D and Cancer

Nearly 30 years ago, researchers noticed an intriguing relationship between colon cancer deaths and geographic location: People who lived at higher latitudes, such as in the northern U.S., had higher rates of death from colon cancer than people who live closer to the equator. (26) Many scientific hypotheses about vitamin D and disease stem from studies that have compared solar radiation and disease rates in different countries. These can be a good starting point for other research but don’t provide the most definitive information. The sun’s UVB rays are weaker at higher latitudes, and in turn, people’s vitamin D levels in these high latitude locales tend to be lower. This led to the hypothesis that low vitamin D levels might somehow increase colon cancer risk. (2)

Since then, dozens of studies suggest an association between low vitamin D levels and increased risks of colon and other cancers. (1,27)  The evidence is strongest for colorectal cancer, with most (but not all) observational studies finding that the lower the vitamin D levels, the higher the risk of these diseases. (28-38) Vitamin D levels may also predict cancer survival, but evidence for this is still limited. (27) Yet finding such associations does not necessarily mean that taking vitamin D supplements will lower cancer risk.

The VITAL trial will look specifically at whether vitamin D supplements lower cancer risk. It will be years, though, before it releases any results. It could also fail to detect a real benefit of vitamin D, for several reasons: If people in the placebo group decide on their own to take vitamin D supplements, that could minimize any differences between the placebo group and the supplement group; the study may not follow participants for a long enough time to show a cancer prevention benefit; or study participants may be starting supplements too late in life to lower their cancer risk. In the meantime, based on the evidence to date, 16 scientists have circulated a “call for action” on vitamin D and cancer prevention: (27) Given the high rates of vitamin D deficiency in North America, the strong evidence for reduction of osteoporosis and fractures, the potential cancer-fighting benefits of vitamin D, and the low risk of vitamin D supplementation, they recommend widespread vitamin D supplementation of 2000 IU per day. (27)

Vitamin D and Immune Function

Flu VirusVitamin D’s role in regulating the immune system has led scientists to explore two parallel research paths: Does vitamin D deficiency contribute to the development of multiple sclerosis, type 1 diabetes, and other so-called “autoimmune” diseases, where the body’s immune system attacks its own organs and tissues? And could vitamin D supplements help boost our body’s defenses to fight infectious disease, such as tuberculosis and seasonal flu? This is a hot research area and more findings will be emerging.

Vitamin D and Multiple Sclerosis: Multiple sclerosis (MS) rates are much higher far north (or far south) of the equator than in sunnier climes, and researchers suspect that chronic vitamin D deficiencies may be one reason why. One prospective study to look at this question found that among white men and women, those with the highest vitamin D blood levels had a 62 percent lower risk of developing MS than those with the lowest vitamin D levels. (39) The study didn’t find this effect among black men and women, most likely because there were fewer black study participants and most of them had low vitamin D levels, making it harder to find any link between vitamin D and MS if one exists.

Vitamin D and Type 1 Diabetes: Type 1 diabetes is another disease that varies with geography—a child in Finland is about 400 times more likely to develop it than a child in Venezuela. (40) Evidence that vitamin D may play a role in preventing type 1 diabetes comes from a 30-year study that followed more than 10,000 Finnish children from birth: Children who regularly received vitamin D supplements during infancy had a nearly 90 percent lower risk of developing type 1 diabetes than those who did not receive supplements. (41)  Other European case-control studies, when analyzed together, also suggest that vitamin D may help protect against type 1 diabetes. (42) No randomized controlled trials have tested this notion, and it is not clear that they would be possible to conduct.

Vitamin D, the Flu, and the Common Cold: The flu virus wreaks the most havoc in the winter, abating in the summer months. This seasonality led a British doctor to hypothesize that a sunlight-related “seasonal stimulus” triggered influenza outbreaks. (43) More than 20 years after this initial hypothesis, several scientists published a paper suggesting that vitamin D may be the seasonal stimulus. (44) Among the evidence they cite:

  • Vitamin D levels are lowest in the winter months. (44) 
  • The active form of vitamin D tempers the damaging inflammatory response of some white blood cells, while it also boosts immune cells’ production of microbe-fighting proteins. (44) 
  • Children who have vitamin D-deficiency rickets are more likely to get respiratory infections, while children exposed to sunlight seem to have fewer respiratory infections. (44) 
  • Adults who have low vitamin D levels are more likely to report having had a recent cough, cold, or upper respiratory tract infection. (45)

A recent randomized controlled trial in Japanese school children tested whether taking daily vitamin D supplements would prevent seasonal flu. (46) The trial followed nearly 340 children for four months during the height of the winter flu season. Half of the study participants received pills that contained 1,200 IU of vitamin D; the other half received placebo pills. Researchers found that type A influenza rates in the vitamin D group were about 40 percent lower than in the placebo group; there was no significant difference in type B influenza rates. This was a small but promising study, and more research is needed before we can definitively say that vitamin D protects against the flu. But don’t skip your flu shot, even if vitamin D has some benefit.

Vitamin D and Tuberculosis: Before the advent of antibiotics, sunlight and sun lamps were part of the standard treatment for tuberculosis (TB). (47) More recent research suggests that the “sunshine vitamin” may be linked to TB risk. Several case-control studies, when analyzed together, suggest that people diagnosed with tuberculosis have lower vitamin D levels than healthy people of similar age and other characteristics. (48)   Such studies do not follow individuals over time, so they cannot tell us whether vitamin D deficiency led to the increased TB risk or whether taking vitamin D supplements would prevent TB. There are also genetic differences in the receptor that binds vitamin D, and these differences may influence TB risk. (49) Again, more research is needed. (49)

Vitamin D and Risk of Premature Death

A promising report in the Archives of Internal Medicine suggests that taking vitamin D supplements may even reduce overall mortality rates: A combined analysis of multiple studies found that taking modest levels of vitamin D supplements was associated with a statistically significant 7 percent reduction in mortality from any cause. (50) The analysis looked at the findings from 18 randomized controlled trials that enrolled a total of nearly 60,000 study participants; most of the study participants took between 400 and 800 IU of vitamin D per day for an average of five years. Keep in mind that this analysis has several limitations, chief among them the fact that the studies it included were not designed to explore mortality in general, or explore specific causes of death. More research is needed before any broad claims can be made about vitamin D and mortality. (51)

About A.B.C.D.E.

Every child needs to learn the ABC’s of life. When it comes to establishing healthy habits, you can teach them how to “ABCDE” (Act Boldly to Change Diet and Exercise).

Why is this important?

  • Good nutrition and plenty of exercise are the building blocks for strong growth, healthy development, and lifelong wellbeing for children.

  • These days, too many children are not receiving the proper nutrition or enough exercise:

    • - They are not eating enough - an estimated 16 to 17 million children live in homes where they are at risk of going hungry (approx. 1 in 6 households).

    • - They are not eating enough healthy food – an estimated 1 in 3 children are overweight and about 1 in 6 (ages 6-17) are obese.

    • - They are not getting enough exercise – only 30% of children (aged 6 to 17) participated in 20 minutes plus of vigorous physical activity on a daily basis. Children need to get 60 minutes of exercise on a daily basis.

What are the benefits of good nutrition and daily exercise for kids?

Mental and behavioral benefits

  • Good nutrition is essential to healthy brain development in children which is, of course, critical to learning.

  • Children who exercise regularly and eat healthily are likely to:

    • - perform better academically 

    • - feel better about themselves, their bodies, and their abilities

    • - cope with stress and regulate their emotions better

    • - avoid feelings of low self-esteem, anxiety, and depression.

  • Establishing healthy eating and exercise habits early in life can lead to long term healthy behavior in adulthood.

Physical benefits

  • Children need a wide variety of nutrients (e.g., protein, complex carbohydrates, healthy fats, minerals, vitamins) to assist in their daily growth and development and to protect them from childhood illnesses.

  • Daily exercise also helps children to build stronger muscles and bones and limit excess body fat.

  • Healthy eating also cuts down on risk for cavities, eating disorders and unhealthy weight control behaviors (i.e., fasting, skipping meals, eating very little food, vomiting, using diet pills, laxatives, or diuretics), malnutrition, and iron deficiency.

  • Healthy eating and consistent physical activity help to prevent chronic illnesses that appear in adulthood associated with obesity, e.g., heart disease, diabetes, high blood pressure, and several forms of cancer.

What are the effects of different settings on the eating and exercise habits of kids?

In the home:

  • Lack of access to healthy, wholesome foods and inadequate physical activity - contributes to kids becoming overweight and not getting adequate nutrition for their growth and development. Children need at least 60 minutes of daily physical activity in the form of physical play or sports.

  • Hunger – kids who do not get enough to eat are at risk of developing chronic health conditions, behavioral problems, academic struggles, anxiety, depression, and even obesity especially if they only have access to poor quality processed food.

  • Unhealthy weight control behaviors - have been found to co-occur with obesity. Many adolescents, particularly teenage girls, have body image concerns and engage in these behaviors threatening both their physical and mental health. 

  • Media effects

    • - Food advertising - targeted at children is dominated by commercials for unhealthy food (e.g., candy, sugary cereals, sugary beverages, processed snack foods, fast food restaurants). Food advertising is pervasive and can be found on multiple media platforms (TV, web, and even embedded in computer games).

    • - Advertising by other industries - often objectifies girls and women, contributing to body dissatisfaction, eating disorders, low self-esteem, and depression.

    • - TV watching – television viewing is linked to childhood obesity because it displaces physical activity, increases snacking behavior while watching, exposes kids to potentially harmful advertising, and reduces their resting metabolism.

At school:

  • Risks to academic achievement - result from children not getting adequate nutrition and physical activity. Hunger can be particularly damaging to children’s progress in school and cognitive development overall.

  • Overabundance of unhealthy foods - too many schools offer poor nutritional choices in the form of unhealthy school lunches or even vending machines filled with candy, processed snacks, and sugary beverages.

  • Lack of opportunities for physical activity - many schools have scaled back requirements for a daily recess and do not prioritize physical education opportunities for children at every age.

  • Peer behaviors – peers can serve as remarkably powerful role models for children and may share their unhealthy eating or exercise habits with them.

  • Stigma of being overweight – can lead to social and psychological distress (e.g., depression, low self esteem). Bullying and teasing from peers can be particularly damaging and teachers and school staff may attribute less desirable personality characteristics to obese youth and their families.

In the neighborhood:

  • Overabundance of unhealthy foods – there are a growing number of communities called “food deserts” where supermarkets and grocery stores are scarce or charge higher prices for healthy foods than processed foods. In addition, many underserved communities are populated with fast food restaurants that are often located near schools and playgrounds.

  • The built environment – lack of adequate and safe parks, bike lanes, playgrounds, recreational facilities, or walkways can restrict opportunities for children and teens to get exercise.

Why are you critical to establishing healthy behaviors in your kids?

  • You are role models

    • - Children are instinctively primed to imitate their parents and caregivers. They are incredibly sensitive to the messages that are sent about eating and exercise. You exert the most influence on your children’s behavior and can model healthy attitudes and habits toward food and physical activity that persist as they grow up.

  • You are gatekeepers

    • - Parents and caregivers control the types of food children have access to in the home and can maximize access to healthy, wholesome foods (fruits, vegetables, lean proteins, whole grains, and low-fat dairy).

    • - You can also monitor children’s diet, exercise, and limit media consumption (TV/video watching, web surfing, and videogames).

  •  You are taste-setters

    • - Parents and caregivers significantly influence the likes and dislikes that children attach to certain foods. These influences can last a lifetime. Each of us can probably remember a favorite home cooked meal from our childhood. There is even research that suggests that this begins in infancy; children who are breastfed may be exposed to different flavors in their mother’s breast milk than the sugars and fats in infant formula. Breastfeeding may provide protection from the development of obesity.

    • - Eating with your children at regular family mealtimes can help establish positive nutrition habits and healthy weights for children.

  • You are advocates

    • - Parents and caregivers can push local leaders to introduce affordable transportation (e.g., bus or shuttle lines) to supermarkets or grocery stores if there are none in their communities.

    • - You can call for the construction of parks or playgrounds and restriction of fast food places in your neighborhood.

    • - You can push school administrators to introduce after-school programs that incorporate physical activity or nutrition education, healthier school lunches, and policies that eliminate the use of vending machines on school grounds.

    • - You along with members of your community can volunteer to coach afterschool sports.

The foods we eat can affect our risk of developing certain types of cancer. High energy and high fat diets can lead to obesity and are generally thought to increase the risk of some cancers. Plant-based diets high in fresh fruits, vegetables, legumes and wholegrain foods may help to prevent cancer.

Diet is just one of the lifestyle factors that influence the risk of developing cancer. Smoking, obesity, alcohol, sun exposure and physical activity levels are also important. Although some foods can affect cancer risk, there is no evidence that specific foods can cause or cure cancer.

Food and some common cancers
Some common cancers (and how they are affected by what we eat) include:

  • Lung cancer – this is the leading cause of death from cancer in the world and smoking is mostly responsible. There is convincing evidence that diets high in vegetables and fruits are protective against lung cancer. It is thought that compounds called carotenoids (present in significant amounts in fruits and vegetables), as well as vitamin E, are probably responsible for some of this effect. However, the use of antioxidant supplements, such as beta-carotene and vitamin E, has not been proven to be effective in either prevention or treatment of lung cancer and may, in fact, increase the risk of developing cancer in those who smoke. While fruits and vegetables may offer some degree of protection, not smoking in the first place is by far the best prevention.

  • Breast cancer – this is the most common type of cancer in women in the world. There is an increased risk of breast cancer with factors such as rapid early growth, greater adult height and weight gain in adulthood. Much of the risk of developing breast cancer involves factors that influence oestrogen levels during a woman’s reproductive life, such as age of menarche (first period), number of pregnancies and breastfeeding practices. Post menopausal women who are carrying too much weight, especially around their middle, have more than twice the average risk of breast cancer. Diets high in mono-unsaturated fat and high in vegetables and fruits may reduce the risk, while alcohol consumption increases the risk.

  • Prostate cancer – a quarter of all new cancers diagnosed in men in UK is prostate cancer. Vegetables, soy in particular may decrease the risk, while a high fat diet that comprises mostly animal fat sources (such as dairy products, fatty meats and takeaway foods) may increase the risk. Lycopene is a potent antioxidant found in tomatoes, tomato-based products, watermelon and strawberries. It may also help lower the risk of prostate cancer.

  • Bowel cancer – this is the fourth most common cancer in the world. Up to 70 per cent of cases can be prevented by following a healthy lifestyle. Keeping a healthy weight, being physically active and a diet high in vegetables and fibre are protective, while consuming a large amount of red meat (especially processed meat) and alcohol may increase the risk.

Foods to ‘eat less’
Foods to limit in your diet or eat less of include:

  • Fatty processed red meats

  • Highly processed foods that are low in fibre

  • Heavily salted and pickled foods.

Foods to ‘eat more’
The strongest protective anti-cancer effect has been shown with:

  • Vegetables, especially raw vegetables or salads

  • Leafy green vegetables

  • Carrots

  • Tomatoes

  • Citrus fruits

  • Cruciferous vegetables like broccoli, cabbage, brussels sprouts, bok choy and other Asian greens.

Include more of these vegetables and fruits in your diet along with other varieties.

Seven a day
Eating seven or more serves daily of a variety of grains, grain products, legumes, roots and tubers will also provide protective benefits against cancer. The less processed the grains, the better. Diets high in refined starch and refined sugar may increase the risk of stomach cancer and bowel cancer.

Meat and bowel cancer
There is now convincing scientific evidence that eating processed meat increases bowel cancer risk. The World Cancer Research Fund (WCRF) has recently recommended that people avoid eating processed meat. Processed meats are any meat that has been preserved by curing, salting or smoking, or by adding chemical preservatives. These meats include hot dogs, ham, bacon and some sausages and burgers.

It is recommended that children are not given processed meats at all. This is because many of the habits we develop as children last into adulthood. Substitutes for processed meats that are recommended for children include poultry or fish, low fat cheese or small amounts of lean meat.

The WCRF also recommends limiting the amount of fresh red meat we eat to 500g (cooked weight) a week. This is because there is convincing evidence that red meat also increases a person’s risk of bowel cancer.

Some research suggests that eating burnt or charred meat may increase cancer risk, but the evidence is unclear.

Fats and cancer
There has been a great deal of interest in the possible association between fat and cancer. Current evidence does not indicate a direct link between fat intake and particular types of cancer (with the possible exception of prostate cancer). However, a high fat diet may lead to obesity, which is a risk factor for several cancers including cancer of the colon, breast, kidney, oesophagus, gallbladder and endometrium.

Supplements are not the answer
Results of studies that show a protective effect of foods containing certain nutrients should not be taken to mean that these nutrients, when isolated and taken as supplements, will provide the same benefits for cancer prevention. In some cases, there has been an increased risk of cancer in those people who take nutrient supplements at doses higher than the amount of that nutrient normally eaten in foods.

Suspect foods examined
While a high energy, low fibre diet may increase a person’s risk of developing cancer, some individual foods have also been singled out as potentially causing cancer (carcinogenic). These include:

  • Artificial sweeteners – such as aspartame, saccharin and cyclamate. Laboratory rats can develop bladder cancer if fed huge amounts of saccharin or cyclamate, although this is at levels thousands of times greater than a normal diet. International studies agree that humans aren’t affected in the same way. Artificial sweeteners are considered safe to eat.

  • Cured, pickled or salty foods – there is no conclusive evidence that red meat causes cancer. However, bacon and other cured or pickled meats contain a substance called nitrate, which has the potential to cause cancer in laboratory animals when eaten in huge doses. How this research relates to humans isn’t clear. To be on the safe side, it is best to limit the amount of cured meats in the diet because they are generally high in fat and salt. Salt has also been associated with an increased risk of stomach cancer and should be consumed in limited amounts.

  • Burnt or barbecued foods – a group of carcinogenic substances called polycyclic aromatic hydrocarbons (PAHs) can be produced if foods are overheated or burnt. Although charred or smoked foods could contain traces of PAHs, experts agree that the amount in the average UK diet is too low to be considered a significant cancer risk. However, when cooking, it’s best to use relatively low temperature methods wherever possible. These include steaming, boiling, poaching, stewing, casseroling, braising, baking, stir-frying, microwaving or roasting. Avoiding char-grilled meats and foods would also be smart.

  • Peanuts – some laboratory animals can develop cancer after eating peanuts that are contaminated with toxin-producing moulds. However, peanuts sold in the UK are generally uncontaminated and contamination is routinely screened for.

  • Alcohol – consuming alcohol increases the risk of cancers of the mouth, pharynx, larynx, oesophagus, breast and liver. The risk is even greater in those people who smoke. Alcohol has also been associated with colon, breast and rectal cancers. Men should drink less than two standard drinks a day and women less than one standard drink a day.

Treating cancer with food
While food plays an important role in preventing some cancers, the therapeutic value of food in treating existing cancer is less clear. It is true that a person with cancer needs excellent nutrition in order to better cope with the physical demands of the illness and the rigours of medical treatment. However, claims that particular foods, vitamins or micro nutrients can kill cancer cells should be viewed with scepticism To date, there is little scientific proof that a particular food or supplement can cure cancer or destroy cancer cells.

Recently some Japanese studies have found that green tea may delay the development and spread of certain cancers. Other studies have suggested that soy may also have a similar effect. Although this work is preliminary, it may suggest a more important role for food in the treatment of cancer in the future.

Nutrition for the person with cancer is important for many reasons, including:

  • The immune system needs bolstering to fight at full strength.

  • The diet may be adjusted to cope with various symptoms, such as constipation, diarrhoea or nausea.

  • Loss of appetite or an increased metabolism means that high energy foods may need to be included in the daily diet.

  • Extra protein may be needed to help prevent loss of muscle from weight loss.

Things to remember

  • High fat, low fibre diets may increase the risk of many cancers, including bowel, lung, prostate and uterine cancers.

  • You can reduce your risk of developing cancer by eating more fresh fruits, leafy green vegetables and wholegrain foods.

  • Even though diet can influence your risk of developing cancer, there is little evidence that special foods can be used to cure existing cancers.

Osteoporosis means ‘bones with holes’. Bones lose their strength and density, become fragile and break (fracture) more easily because of calcium loss. Breaks are most common in the spine, hip and wrist and often occur after only a minor fall or knock. Osteoporosis particularly affects women in their middle and later years, although some men are also affected.

Most people show no signs of developing osteoporosis until a fracture occurs. Both men and women can take steps from a young age to avoid developing the condition in later life. Reduce your risk of fractures by taking steps to prevent and treat osteoporosis (or brittle bones) and avoid falls wherever possible. Activity and a healthy diet rich in calcium and vitamin D are both important.

Osteoporosis and bone growth
Bone is formed by specialised cells. Like the rest of the body, bone is constantly being broken down and renewed. It is living tissue that needs exercise to gain strength, just like muscle. In the early years of life, more bone is made than is broken down, resulting in bone growth. By the end of your teens, bone growth has been completed and ‘peak bone mass’ is achieved.

Sex hormones, such as oestrogen and testosterone, have a fundamental role in maintaining bone strength in men and women. The fall in oestrogen blood levels that occurs during menopause results in accelerated bone loss. During the first five years after menopause, the average woman loses up to 10 per cent of her total body bone.

Fractures of the spine caused by osteoporosis can lead to loss of height, pain and changes in posture such as the ‘Dowager’s hump’. This hump is caused when spinal fractures are compressed due to the force of gravity, resulting in an abnormal bending of the spine (kyphosis).

Symptoms
Osteoporosis causes no specific pain or symptoms. However, it does increase the risk of serious or debilitating fractures. If you think you may be at risk of developing osteoporosis, see your doctor.

Risk factors for osteoporosis
Several factors can place a person at risk of osteoporosis. Risk factors include:

  • Family history of osteoporosis (mother, sister or grandmother)

  • Inadequate amounts of dietary calcium

  • Low vitamin D levels

  • Cigarette smoking

  • Alcohol intake of more than two standard drinks per day

  • Caffeine intake of more than three cups of tea, coffee or equivalent per day

  • Lack of physical activity

  • Early menopause before the age of 45

  • Loss of menstrual period if it is associated with reduced production of oestrogen, which is vital for healthy bones (the menstrual cycle can cease following excessive dieting and exercise)

  • Long-term use of medications such as corticosteroids for rheumatoid arthritis and asthma.

Some conditions place people at a higher risk of osteoporosis. These conditions include:

  • Thyroid disease or an over active thyroid gland

  • Rheumatoid arthritis

  • Chronic liver and kidney disease

  • Conditions that affect the body’s ability to absorb nutrients, such as Crown’s disease, coeliac disease and other inflammatory bowel conditions.

Preventing osteoporosis
Both men and women can take steps from a young age to prevent osteoporosis by making sure that they:

  • Have a healthy and varied diet with plenty of fresh fruit, vegetables and whole grains

  • Eat calcium rich foods

  • Absorb enough Vitamin D

  • Avoid smoking

  • Limit alcohol consumption

  • Limit caffeine

  • Do regular weight bearing and strength training activities.

A varied and calcium rich diet is the key
We need calcium to build and maintain strong and healthy bones, help our muscles work and support our nervous system. Good sources of calcium include:

  • Dairy foods – low fat varieties are available to reduce the risk of weight gain or raised cholesterol levels

  • Canned fish with edible bones – for example, sardines.

The minimum recommended daily intake of dietary calcium is:

  • Infants (under 12 months) – 210–270mg calcium per day

  • Children (over four years) – 700–1,000mg calcium per day

  • Adolescents – 1,300mg calcium per day

  • Women under 50 and men under 70 – 1,000mg calcium per day

  • Post menopausal women and men over 70 – 1,300mg calcium per day.

Adequate vitamin D
Vitamin D levels are increased with sun exposure. People who are housebound or who dress with most of their body covered are at risk of vitamin D deficiency. The majority of women have inadequate levels of vitamin D during winter months. All that is needed is 10–20 minutes of sun exposure to the arms and face daily, without sunscreen and not through glass. Sun exposure is safest before 11am or after 3pm.

Avoid smoking
Evidence has shown that smokers have a lower bone density. Nicotine is known to be toxic to bone cells.

Limit alcohol intake
Excessive alcohol consumption is associated with the development of osteoporosis. Restrict your alcohol intake to no more than two standard drinks on any one day for both men and women to reduce your risk. Everyone should have at least two alcohol-free days each week.

Reduce caffeine intake
A large amount of caffeine (more than two to three cups per day of cola, tea or coffee) has also been associated with an increased risk of osteoporosis.

Do regular weight bearing and strength training activities
You should exercise at least 30 minutes three to four times a week to maintain healthy bones. Recommended activities are:

  • Walking

  • Jogging

  • Tennis

  • Dancing

  • Using weights.

This helps maintain bone strength and balance so falls are reduced.

Diagnosis
The most reliable way to diagnose osteoporosis is to measure bone density using a DEXA scan. This is done with x-ray technology that involves minimal radiation, is accurate and can be used to follow up treatment.

Ultrasound tests are available at many pharmacies and involve an ultrasound measurement of the heel. These tests are not as accurate in assessing for osteoporosis as a DEXA study and are not recommended by doctors.

It’s never too late for treatment
If you have osteoporosis, it is never too late to seek treatment. Treatment can halt bone loss and significantly reduce the risk of fractures. It is important that your doctor excludes other medical conditions that can cause osteoporosis, including vitamin D deficiency.

Medications and treatments are available to strengthen bones and prevent fractures by slowing down bone loss. They may improve bone density in women with osteoporosis after the menopause.

Available medical treatments include:

  • Bisphosphonates – such as alendronate, risedronate and zolindrinic acid, which can be combined with vitamin D and calcium

  • Strontium ranelate – also called Protelos

  • Selective oestrogen receptor modulators (SERMs) – in the form of raloxifene

  • Vitamin D derivatives and calcium supplements

  • Hormone replacement therapy (HRT) – short-term use of oestrogen and progestogen at menopause.

Other potential therapies that may be used as treatment include parathyroid hormone.

Hormone replacement therapy
All treatments for osteoporosis aim to prevent fractures. Oestrogen replacement at menopause prevents bone loss and fractures, but the effect lasts only as long as oestrogen is used.

Oestrogen can be is used to prevent fractures mainly for younger women with premature menopause. This is because most fractures do not occur until after the age of 65 and long-term oestrogen use is not recommended.

Falls are a risk for people with osteoporosis
For people with osteoporosis, even minor trauma – such as coughing, knocks on the limbs and simple falls – can lead to fractures. Falls are a particular problem in the elderly as they are often more likely to result in fractures, particularly of the hip. Any fracture occurring from minimal trauma should be investigated as it may indicate underlying osteoporosis.

There are several ways to reduce your risk of falls. It may be necessary to see a physiotherapist and/or occupational therapist to provide assistance with walking aides and ensure your home environment is safe. Talk with your doctor or contact your community health centre to find the services you need.

Things to remember

  • Osteoporosis occurs when bones lose their density and strength.

  • A healthy lifestyle throughout life (adequate dietary calcium and regular physical activity) can help prevent osteoporosis.

  • Oestrogen replacement helps maintain bone density in women with premature menopause.

The things that can have a positive impact on our health are many and varied, and often it can be surprising to learn that something that doesn't intuitively seem to have anything to do with our health can actually have a big impact on it one way or another. For instance take jellyfish – you likely have no reason to have thought of jellyfish as a great source of nutrients, or as the key to unlocking secrets of our own health – but in fact they are both. Here we will look how the humble jellyfish can benefit your health and how they might one day help us to better understand the human body.

About Jellyfish

Jellyfish are remarkable creatures. While you and I are 'mostly water' jellyfish take this to the extreme and are only 5% solid matter and 95% water. They are invertebrates meaning they lack a spine and so they don't swim or walk but rather just 'drift' with the currents and go wherever they may take them.

There are a vast number of jelly fish species and these come in a range of shapes and sizes – sometimes with tentacles up to 100 feet long. Some will drift in shallow coastal waters but others prefer depths of up to 12,000 feet. They live three to six months and they come in a variety of colors.

And if you want an amazing jellyfish fact how about this – the Turritopsis Nutricula Jellyfish is a species of jellyfish that never dies. Yes this jellyfish is biologically immortal meaning that if it's never in an accident or caught by predators then it won't die. This is because it can revert itself back to its neonatal state as a newly born 'polyp' and thereby rejuvenate all of its cells.

Eating Jellyfish

Eating dried jellyfish is highly nutritious and they contain a lot of good substances. Jellyfish are one of Asia's most popular foods and are served dried and chopped into small pieces and boiled to add a crunchy texture and remove salt. Their health benefits are that they contain a lot of calcium binding proteins which improve memory and help to fight age related cognitive decline. In one study 56 participants were put on a jellyfish diet and it was found that 57% of them experienced memory improvements. Normally our brain produces calcium binding proteins of its own, but as we get older these reduce in number. This is a problem as the proteins are used in order to regulate the amount of calcium in the brain cells and this can then slow down various brain functions.

At the same time dried jellyfish contain collagen which may be helpful for the treatment of arthritis and visible signs of aging once again. All this suggests that while you're not going to become immortal like the Jellyfish, you will nevertheless gain some youthfulness as a result of eating them. Jellyfish are also harvested for their collagen and this can be used in many beauty products.

Most fundamentally though, the jellyfish is mostly protein and water meaning that it is a very lean source of amino acids with very few carbohydrates or fats making them the perfect diet food.

Swimming With Jellyfish

Jellyfish sting as a natural response to touch and this is their primary defense mechanism against predators. Some of these stings are deadly – such as stings from the box jellyfish but in many cases it is perfectly safe to swim with jellyfish. Some stings are not strong enough to breach the skin at all while others are barely noticeable. As jellyfish are so calming and beautiful many people find it fascinating and therapeutic to swim with them. If you enjoy the thought of swimming with jellyfish then the best way to do so is to head to Clear Lake on the island of Eli Malk in Palau. Here you will encounter the 'golden pool' filled with countless 'golden jellyfish' which have lived there without evolving for millions of years. Because the lake is cut off and so high in nutrients, the jellyfish have lost their sting and that makes them completely harmless to swim with. Meanwhile more and more people are taking an interest in keeping moon jellyfish as pets.

Jellyfish in Biotechnology

The real benefits of jellyfish to mankind however lie in their unique genetics. The luminescence that they produce for instance (the green fluorescent protein gene in crystal jellyfish specifically is responsible) is often used as a 'biomarker' or 'biotag' to allow scientists to identify the activation of genes. They have been used to create glowing cats, mice and other animals and this then indicates that the other changes they have made to those animals' genetics are also working. Luminescent cats most recently have been used to research a potential cure to AIDS. This has additionally allowed scientists to see inside living cells and this has helped to revolutionize medicine and our understanding of our cells. And finally the paralyzing aspects of jellyfish venom it is hoped may help us to unlock the keys to the human cardiovascular system.

Gluten intolerance, a genetic disorder caused due to adverse reactions of the body to a protein called gluten, which causes inflammation of the upper small intestine resulting in various health complications.

Gluten is a mixture of two components – gliadin and glutenin, which results in a sticky dough like texture when mixed with water. For some people, gliadin does not suit the body and causes inflammation in the small intestine. Due to this, the tiny protrusions called villi found in the interior walls of the intestine are not able to absorb vital nutrients. Excess of calcium, minerals, vitamins and fat are passed in the stools. Since the nourishment is not really adequate, deficiency related disorders are common.

Gluten intolerance can result in sudden and unhealthy weight loss or weight gain of the individual. For instance, diarrhea results in weight loss as excessive water from the body is removed along with some vital nutrients. Dehydration results in loss of weight. Similarly, anaemia, exhaustion, fatigue and digestive disorder generally results in unhealthy weight loss of the person. However, depending on the nature of thyroid disorders caused due to gluten intolerance, hypo or hyper thyroid syndrome can either increase or decrease the weight of the person.

In the case of pregnant women, malabsorption of nutrients can cause serious health complications resulting in congenital malformation, miscarriages and also excessive weight gain during pregnancy and even obesity. Abnormal absorption of fat and excess passing of fat and calcium in stools can also result in weight abnormalities.

Some people who have this disorder exhibit clear symptoms while for some, there are some abnormalities seen in the digestive tract. High amount of damage is also seen in the small intestine and hence, the diagnosis may become slightly difficult due to such varied symptoms from individual to individual.

Gluten intolerant people have to avoid food items that contain barley, rye and wheat in any form (as a staple ingredient or a by-product). For example, certain cereals, cookies, bread, lipsticks, medications and vitamin supplements contain hidden gluten content in them. They have to be completely avoided to prevent further damage to the intestine. Otherwise, the chances of developing gastro intestinal cancer are pretty high.

In addition, patients suffering from gluten intolerance should balance their emotional levels and stress levels in order to prevent the worsening of general health and aggravating the symptoms of the disorder. Breast feeding by mothers for a longer period of time and starting gluten-containing food products at later ages for the child are also some ways to prevent gluten intolerance among children.

Reports suggest that around 2 million people in America suffer from gluten intolerance and the related disorders. People from Northern European descent are found to be more prone to this disease. Since this disorder is genetic in nature, if one family member contracts this disease, there is also a chance that the descendants may also be affected at a later point of time. Hence, if there is constant problem with general health and fitness, biopsy and blood test needs to be taken to diagnose this disorder.

There appears to be a difference of opinion concerning the merit of fruits versus vegetables. There is a small but zealous group of people called fruitarians who maintain that fruit is the only proper food for mankind. Then there are some like myself who favor vegetables for good health and proper nutrition. In fact, I feel that fruit, even in the broadest possible range and variety, can never provide sound health and long life.

The fruitarians maintain stoutly that through the use of fruit they enjoy good health or have regained good health after being sick. I sometimes demand proof of their statements and they offer it in various ways. For example, they use their own good health as testimony that an all-fruit diet is the proper course to follow. They also cite the gorillas and other primates as examples of fruit eaters who display great strength and good health.

Back a few years ago I could not refute these statements and even though I could not accept their theory that fruit and fruit alone was the proper diet for man, I just permitted the matter to rest. However, after a lot of study and investigation, I learned that there are few, if any, robust and healthy fruitarians. I do not know of one 100% fruitarian who has lived on a totally fruitarian diet for ten straight years, let alone 25 years or more. Therefore, if they cannot show me an example .... that is, a good example .... of someone who has remained on a strictly fruit diet for ten years or more, then what have they to offer as proof? On the other hand, I have known a few myself who tried a totally fruitarian diet and all came 'a cropper'.

Then I found proof that the statement that the gorilla eats only fruit is nothing but a myth .... and a stupid ridiculous myth at that! For years the fruitarians have been citing gorillas or other primates as an example of the value of a strictly fruitarian diet. However, upon studying the eating habits of gorillas, I learned that fruits constitute less than 10% (actually closer to 5%) of the total diet of gorillas. A detailed comprehensive book, written and tabulated by one who spent some years among them, gives this proof conclusively and it is available to anyone who wishes to get it. The title of the book is, "The Mountain Gorilla Ecology and Behaviour," written by George B. Schaller and published by the University of Chicago Press.

The reason I have taken the trouble to bring this whole matter of the gorilla and the fruitarian diet into the open is that with the exaggerated claims of the fruitarians and the fact that the fruitarian diet is pleasing and delectable, many people might be led to believe their claims and perhaps do themselves serious harm. I have witnessed just that in at least four instances.

My many years of reasearch and study have clearly and unmistakably indicated that vegetables are a better source of nutrition than fruits. It is admitted that most fruits are more pleasant, more palatable and more delectable and no doubt require less work in preparation than vegetables, but it appears certain that vegetables are more valuable nutritionwise.

I stress to you readers who are seeking health that you do not make the mistake of trying to regain or maintain your health on a diet of fruit juice alone. I maintain that it cannot be done.

It is my way of life to read and study nutrient charts and from these charts I learn and then base my opinions. Thus, when I say that vegetables contain many more essential nutrients than fruit, I want you to know that I have investigated the matter.

One must not judge the nutritional value of fruits and vegetables by taste and flavor alone. A vegetable I consider to be one of the finest — namely, cabbage — is acceptable when sliced, shredded or chunked but it is much, much less palatable in the juice form. In fact, I know of few if any less desirable juices than cabbage. However, in an actual research project it was found that cabbage juice therapy was a safe and almost positive way to rid oneself of ulcers.

Again, do not judge the merit of a juice by palatability alone. Remember, we go on a juice regimen in order to improve or regain our health .... not as a fad or for fun. It is strictly a means of survival, so flavor is not of importance. On the other hand, one need not sacrifice everything nor follow a spartan regimen. One can have a fair amount of the more enjoyable fruit juice .... for example, one-third fruit juice and two-thirds vegetable juice .... but I would strongly advise that they not be mixed. Although an apple will improve the flavor of many vegetable juices, I advise that you take your fruit and vegetable juices separately.

It is important, in my opinion, that the variety of fruits and vegetables used be as broad as possible. Do not restrict yourself to the juices of one or two fruits and one or two vegetables. Make positively sure that you get a broad variety. In this way your diet will be properly balanced .... and this will be reflected in the way you feel and the way you look. You will note, if you study charts, that some juices contain large amounts of one nutrient or element whereas other juices contain large amounts of other nutrients or elements.

It is claimed that fruit juice is the cleanser of the body. No doubt you have noticed that fruit juice cause a much greater frequency of urination and, thus, they are generally referred to as cleansers. In my opinion, the fact that they make you urinate frequently does not necessarily mean that they are cleansers .... but that is the value that many authorities attribute to them. However, you can be sure that a lot of fruit means a lot of urine.

A few years ago I had a friend visiting me from Alaska and he confided in me that he was fearful that he was developing diabetes. I asked him why he was fearful and he told me that recently he had been urinating much more than usual. He also told me that, knowing he was coming to visit me, he had gone on a fresh fruit diet. I pointed out that a diet of fruit, especially melons, will greatly increase the flow and frequency of urine. It turned out he had nothing to fear .... it was simply 'much fruit, much urine'.

While fruit juices are referred to as cleansers of the human body, vegetable juices are called the regenerators or builders and this tends to bear out my belief that vegetable juices contain more nutrients than fruit juices. My studies reveal that vegetable juices contain practically all of the nutrients required to build and sustain the human body in optimum health.

For those who are addicted to drinking and consuming large quantities of tea, coffee, milk or other beverages, I would like to suggest that drinking fruit or vegetable juices would be far more beneficial health wise and, of course, fruit or vegetable juices are not addictive. Desirable and pleasant, yes, but addictive, no! At the same time I would like to remind you rather emphatically that fruit or vegetable juice is not just a refreshing drink like water or pop, but it is a food .... and a potent, health-giving food at that!

In using juices, remember, no seasoning should ever be added. In fact, to add seasoning of any kind would detract from the value of the juice or create an imbalance. Never, ever add salt to, any fresh juice. In fact, if you value your health, do not add salt to any food.

My enthusiasm for fresh vegetable and fruit juices did not spring up overnight. It slowly developed over a period of many long years, during which time I watched experiments and learned just what these juices can do.

Well, I have a love affair with vegetable juices and I want to tell you that that love affair is based on the soundest foundation that exists on earth .... I saw with my own two eyes some of the lives that were saved by vegetable juices. Yes, I actuallly saw terminal cancer cases turned back to good health even after the medical doctors said that no more could be done. It is not hard to have a love affair with such a virile lover!

After years of denying the health benefits of sunlight, conventional researchers are finally starting to recognize the important role that ultraviolet light plays in human health. Getting sunlight on your skin, research now shows, is extremely important for preventing and even reversing chronic diseases. I'm talking about prostate cancer, breast cancer, cervical cancer, mental depression, osteoporosis and even, to some extent, type 2 diabetes. The interactions between sunlight and body chemistry for these diseases are quite complex, and I'm not going to go into them all here, but let me give you the highlights.

Vitamin D is essential for calcium absorption

First, you most likely already know the importance of calcium for your health. If you don't have enough calcium circulating through your blood, you're going to have cardiovascular problems and you will probably end up with heart disease. Calcium is crucial for healthy nervous system function, as well.

If you've read any of the promotional material about coral calcium and all the different diseases that calcium can prevent or even help cure, then you have a pretty good idea about some of the practical applications of calcium. Now, I don't think that calcium all by itself is going to reverse many chronic diseases, but without calcium, there's no question that you will be accelerating those diseases and reducing your lifespan.

Here's the kicker: Without vitamin D in your small intestine, your body will not absorb calcium even if you take an excess of supplements. This is the single most important point, and I don't think I've ever been able to get this point across with enough emphasis. You must have vitamin D in your body in order to use calcium. So if you're out there taking coral calcium supplements or eating a lot of green leafy vegetables, but not getting sunlight or ultraviolet radiation on your skin, then you are probably not absorbing the calcium you are going to such great trouble to ingest.

Reversing osteoporosis with sunlight

Sunlight can actually reverse osteoporosis. A lot of senior citizens are taking calcium supplements but not getting sunlight, so the calcium is passing right through their bodies. As a result, they're losing bone mineral density. However, by adding vitamin D to the equation through sunlight (remember, your skin generates vitamin D in response to sunlight exposure), senior citizens can start assimilating calcium and rebuilding their bones.

This is information that doesn't get told to senior citizens, and modern doctors don't even understand it. They think that you treat osteoporosis with drugs, which is ridiculous. The only thing you need in order to treat osteoporosis is sunlight, calcium and a little bit of physical exercise. You will rebuild bone mineral density very rapidly on that kind of program.

The bottom line: Get some sun on your skin

Make sure that you're getting sunlight on your skin. If you do this one thing, and do it consistently, it will create such a positive health outcome. Sunlight will make a world of difference in your life. It will change your mood. It will change your biochemistry. It will enhance your bone mineral density, and it will help your body beat or prevent various forms of cancer.

In fact, vitamin D is a key compound in the regulation of cancer cell growth. Researchers are just now figuring out that people who are chronically deficient in vitamin D, which includes most Americans, are at far greater risk of a variety of different cancers. Vitamin D has been shown to be the single most powerful chemical compound known to medical science for preventing hormone-related cancers such as breast cancer and prostate cancer.

Why antioxidants are important before exposing yourself to UV light

Now, you might ask, "What if I can't get sunlight? What if I live in a northern climate or a cloudy climate and I just can't get sunlight?" First, as I said before, you can go visit a tanning salon. This is only the second-best choice. Personally, I don't like artificial light even if it is ultraviolet -- sunlight is far healthier for you because it has a full spectrum of energy that's not found in a tanning bed. But a tanning salon is your best alternative. If you can't get out in the sunlight, go sign up with a tanning salon.

If you do that, it is crucial that you supplement with superfoods and high levels of antioxidants. If you don't have high levels of antioxidants in your tissues, you may suffer skin damage from excessive ultraviolet radiation. By taking high levels of antioxidants, however, you will build up an internal sunscreen, and your skin's response to sun exposure will be very different. It will be healthy and adaptive, meaning that you won't burn. Instead, you will tan. This is true even if you've never tanned in your life.

I know exactly what I'm talking about here -- I used to be one of the most fair-skinned people around. I would sunburn very easily. I grew up in the Midwest, and after just half an hour in the summer sun I would be burned beet red. My skin would peel, and I would be in pain for days. Now, thanks to the antioxidants I'm taking, I can go out in the desert in Arizona, in the middle of the summer, and spend three hours under the sun with no sunscreen whatsoever and not burn at all. What's the difference? Do I have new skin and new genetics? Of course not. I just have better nutrition.

This is one of those truths about health that medical science currently considered heresy, but will eventually acknowledge as true in the years ahead.

Protect your skin with outstanding internal nutrition

Nutrition makes all the difference when it comes to sun exposure. Keep in mind that it takes a little bit of time for this nutrition to work its way into the tissues of your skin. So if you haven't been engaging in good nutrition but you want sunlight, don't make the mistake of jumping out into the sun right away. Give yourself a couple of weeks following high-density nutritional supplementation first (and use whole food-based supplements, not the cheap chemical multivitamins sold at retail).

One of the best products you can get to assist with this is called astaxanthin. Astaxanthin will greatly boost the antioxidant count in your tissues, protect you from sunlight, and function as an internal sunscreen. It will also reduce inflammation and protect your nervous system, including your eyes, from damage from a variety of sources, including oxidative damage, free radical damage, and damage from ultraviolet radiation. Getting astaxanthin into your diet is very wise.

You should also add superfood supplements to your diet. If you're not already taking a green foods product, I strongly urge you to order one and make it part of your daily diet. If you don't like the taste of it at first, keep in mind that you will get used to it, and you can start small. Blend half a teaspoonful into your favorite drink. I recommend bananas and either milk or soymilk. That makes a delicious milkshake. You can blend in a little supergreen powder and start increasing your dosage until you're putting in a couple of heaping tablespoonfuls each morning. Believe me, you'll not only get used to the taste, you'll come to like it.

You can also buy a variety of other nutritional supplements. There's a product available at health food stores called Berry Green. It's a whole food concentrate. It's important that you don't make the mistake of relying on isolated vitamins; eat whole food concentrates if you want to boost your antioxidant count, which will help protect you from sunburn.

Alternative food sources of vitamin D

If you can't get into a tanning booth, or don't want to, another alternative to sunlight is to find other sources of vitamin D. The best way to do that is to drink cod liver oil on a daily basis. A tablespoonful of cod liver oil would go a long way toward boosting your vitamin D count and protecting you from chronic disease.

Don't assume that this tastes unpleasant just because it's from fish. Cod liver oil is actually close to tasteless. It's sort of like drinking olive oil or corn oil. Additionally, you can buy mint- or orange-flavored cod liver oil from health food stores and it won't taste objectionable at all. You can even mix it into your blended morning drink if you want. Either way, get vitamin D into your diet.

Don't believe for a second that vitamin-D-fortified milk is going to give you enough vitamin D. Most of the vitamin D in milk has been destroyed by excess exposure to light. It's a terrible way to get vitamin D. The most efficient vitamin D supplement is still fish oil, and cod liver oil is the best way to go.

There are four main points you should take from this:

  1. You have to get sunlight into your life in order to be healthy and prevent or even reverse major chronic diseases. Start getting more sun.
  2. Boost your antioxidant count, because antioxidants will protect you from the risk of overexposure to sunlight. Astaxanthin, green foods powder, Berry Green, and other green foods are all excellent sources. Get those supplements now and find ways to work them into your diet starting today.
  3. If you can't get sunlight, visit a tanning booth to get ultraviolet radiation. It's a secondary choice, but it's better than doing nothing. Remember not to use tanning booths for too long, and be sure to have great nutrition for at least 30 days before tanning in a booth.
  4. If you can't get sunlight or get to a tanning booth, find other sources of vitamin D. The best source is cod liver oil, which you can mix into a delicious shake the same as you would most whole food supplements.
If you do these things, you will simply amaze your doctor with your improved health. You will have healthier bones, tissues and blood. You'll help prevent cancer, depression and gum disease. You'll heal more quickly from injury, and your mood will markedly improve. This is the power of vitamin D, a nutrient so miraculous that if it could be patented and sold for profit, it would be among the top selling drugs in the world.

Along with a balanced diet and regular exercise, multivitamins are a good way to stay in good health. For just pennies a day, they may help lower your risk of cancer, heart disease and osteoporosis as well as prevent some birth defects. When undertaking body weight management, taking a multi-vitamin will keep you strong and healthy. Since you are changing your eating habits in one way or another, you want to make sure you are getting in a good amount of your essential vitamins and minerals. Look to include vitamins: A, D, E & B-Complex (B1, B2, B6, B12), minerals: calcium, magnesium, potassium, copper, manganese, chromium, zinc, iodine, boron, iron & selenium in addition to an anti-oxidant. There are many misconceptions about vitamins and the health benefits they offer.
Vitamins play an important role in keeping the body healthy. However, taking large doses of certain vitamins can actually be harmful. For most people, it is best to get the vitamins our bodies need from eating a variety of healthy, unprocessed foods rather than by taking supplements. Vitamin supplements are frequently misused and taken as a form of medicine to treat ailments such as colds or to counteract lifestyle issues such as stress. Contrary to popular belief, vitamins aren’t drugs or miracle cures. They are organic compounds that participate in various metabolic functions. High-dose supplements should not be taken unless recommended under medical advice. Isolating the ‘active ingredient’ is not the answer Proper balance and adequate levels of essential nutrients is important for a range of complex processes in our body. When vitamins are taken as supplements, they are introduced into the body at levels that could never be achieved by eating even the healthiest of diets. They are also sent in ‘alone’. When they occur in food, vitamins have many other companions to help them along the way. For instance, provitamin A (beta-carotene) in food is accompanied by hundreds of its carotenoid relatives. Simply taking a vitamin pill is not an instant fix for feeling run down or lacking in energy. It is the combination of a whole range of compounds (most of which we probably don’t even know about) in plant foods that gives us the protection. When you artificially remove one of them and provide it completely out of context, it may not be as effective and, in the case of some vitamins, can have negative effects
Recommended dietary intakes
 Many people mistakenly believe that since small amounts of vitamins are good for you, then large amounts must be better. In the case of vitamins, it is better to follow the rule of ‘less is more’. The vitamins A, D, E and K are fat soluble, which means they can be stored in the body. Taking high doses of these vitamins, especially vitamin A, over a long period of time can result in harmful levels in the body unless you have a medically diagnosed deficiency. Some of the water soluble vitamins can also cause side effects in high doses. For instance, vitamin B6 has been linked with nerve damage when taken in large doses. For a healthy adult, if supplements are used, they should generally be taken at levels close to the recommended dietary intake (RDI). High-dose supplements should not be taken unless recommended under medical advice. Deficiencies and illness
The human body is able to store vitamins. The fat soluble vitamins A, D, E and K can be locked away in the liver and body fat and stored for a long time. The water soluble vitamins, including B-complex and vitamin C, are mostly only stored for a shorter period of time. A vitamin deficiency takes weeks or months before it will affect your health. For instance, it would take months of no vitamin C before you developed scurvy. An occasional lapse in good eating will not harm you if your usual diet consists of a wide variety of fresh foods.
Sometimes supplements are needed
 Supplements do have a role to play for some groups of people. For instance, people on long-term restrictive weight loss diets or people with malabsorption problems such as diarrhoea, coeliac disease, cystic fibrosis or pancreatitis can benefit from supplements. Folic acid supplements are strongly recommend for women planning a pregnancy to reduce the risk having a baby with neural tube defects, like spina bifida. People who are advised by their doctor that they need to take vitamin supplements are encouraged to consult an accredited dietitian, who can work with their doctor to provide dietary advice related to the person’s situation. If you need to take a supplement, it is best to take multivitamins at the recommended dietary level, rather than single nutrient supplements or high-dose multivitamins.
The common cold and vitamin C
Many people think that vitamin C helps prevent the common cold. Despite exhaustive research across the world, there is still no strong evidence to prove this. Some studies have shown that taking large doses of vitamin C (more than 1,000mg per day) continuously or at the start of a cold may ease some of the symptoms and the duration, on average, making it about half a day shorter. It does not prevent you catching a cold. You also need to consider the health risks associated with taking large doses of vitamin C. Large doses may cause nausea, abdominal cramps, headaches, fatigue, kidney stones and diarrhoea. It may also interfere with your body’s ability to process (metabolise) other nutrients – for example, it could lead to dangerously raised levels of iron. Excessive amounts of vitamin C in the body can also interfere with medical tests, such as diabetes tests, giving a false result. Adults need about 45mg of vitamin C per day and any excess amount is excreted. Stress, depression and anxiety Some vitamin and omega-3 fatty acid deficiencies can lead to emotional disturbances. However, if you are feeling run down, it is more likely to be due to stress, depression or unhealthy lifestyle habits (such as insufficient sleep or smoking) rather than a vitamin deficiency. Feeling under pressure doesn’t automatically lead to a vitamin deficiency, so taking a vitamin supplement won’t necessarily make the stressful feelings go away. More serious mental illnesses, such as schizophrenia and bipolar disorder, aren’t caused or prevented by vitamins, although a healthy diet and good nutrient intake can help support a person to better cope with their condition.
Vitamin E and heart disease
Vitamin E is widely promoted as a beneficial antioxidant that can help prevent heart disease. Unfortunately, several large-scale reviews have conclusively found no evidence that vitamin E supplements prevent death from heart disease. In fact, there may be greater risk of all-cause death from taking such supplements.
Cancer cures
Vitamin A in large doses does not cure cancer and can be toxic, particularly if taken as pills rather than food. There is some evidence that vitamin E could play a small role in preventing some cancers although, equally, there is evidence that it could hasten the onset of other types of cancer; however, this has not been conclusively proved or disproved. While it is argued by some that megadoses of antioxidants can help with the effectiveness of conventional cancer treatments, such as chemotherapy and radiotherapy, the evidence is far from supporting this. In fact, it has been shown that megadoses of antioxidants can actually interfere with some medical treatments of cancer by helping to protect the cancer cells that the therapies aim to eradicate.
Some research findings
A number of studies into supplement use have shown negative findings. For instance: Vitamin A (beta-carotene) was thought to reduce the risk of some cancers but has been linked to an increase in others, such as lung cancer in smokers, if taken in supplement form. Several long-term studies have shown that prostate, breast and lung cancer risk are not decreased by taking high-dose supplements containing vitamins E or C or selenium. People taking high-dose vitamin E supplements have been found to have higher rates of early death (mortality).
Anti-ageing vitamins
Vitamin E is often singled out as the potential fountain of youth. However, there is no evidence that taking large doses of any vitamin can either stall or reverse the effects of ageing. Neither can any one vitamin restore a flagging sex drive or cure infertility. Vitamins and chronic disease
In developed countries, vitamin deficiency is rare but the inadequate intake of some vitamins is not so rare and has been linked to a number of chronic diseases. These include cardiovascular disease, cancer and osteoporosis. There is ongoing research to study the effects of taking vitamin supplements to prevent chronic disease, and evidence around nutrition and diet is constantly changing. It is important you consult with your doctor before taking vitamin supplements in high doses.
Things to remember
Vitamins are not drugs or miracle cures. Taking large doses of vitamins can be harmful because your body only needs vitamins in very tiny amounts. Eating plenty of fruits, vegetables, whole grains and cereals will give your body most of the vitamins your body needs at the right level and in the right balance. Vitamin supplements can’t replace a healthy diet, but a general multivitamin may help if your diet is inadequate.
People who may need vitamin supplements include pregnant and breastfeeding women, people who consume alcohol in amounts over the recommended level, drug users and the elderly.

At any UK supermarket, health shop or chemists, you will find a wide range of dietary supplements.  When faced with different brands of various minerals, one asks oneself “which one?”.

Which ones to take indeed?  Let’s face it, all the vitamins and minerals one requires can be found in a healthy, balanced diet, which is varied with protein (in the form of meat and dairy products) and fresh fruit and vegetables.  However, peoples’ busy lives can be so pressurised and busy, that some days we don’t get a “healthy balance”.  This means that we miss out on the essential vitamins and minerals, including zinc, l’arginine, vitamins A – D and K.

Some supplements are enhanced with prebiotics and probiotics, which encourage the growth of “friendly bacteria”.  Prebiotics are supplements which provide the bacteria with essential nutrients, encouraging them to grow.  Probiotics are the actual friendly bacterial cultures.  When ingested, the bacteria from the probiotic supplements help increase the numbers of friendly bacteria already in your gut.

Extra vitamins and minerals to a healthy diet aren’t “essential”, however they can boost our lives emotionally by encouraging vigour and zest.  Natural minerals can even help enliven our sex lives.  Zinc and potassium are minerals which boost sperm count, and can be found readily in the form of multivitamin tablets, or they can be bought and taken individually.

Natural aphrodisiacs are widely available in the form of herbal supplements.  These tablets are crammed full of all the good stuff:  L-Arginine, an essential protein; zinc, to enhance sperm count and testosterone; gingko, a natural stimulant to increase energy levels and enhance performance.

So, when choosing the mineral for you, consider the following:

1.  What are you lacking?  If your diet is unbalanced at the moment, consider taking on board the essential vitamins and minerals.  i.e. the ones that you need to be healthy.  So, vitamins A-D.

2.  If you have a balanced diet, but lack zest and vigour, consider natural stimulants such as gingko and guarana.

3.  If you want to boost and enliven your sexual performance, why not consider a supplement which encompasses lots of different minerals and stimulants?  Search for herbal supplements for men and blue pill, to see what’s on offer.

4.  Price – is it really affordable?  As we can get all the vitamins and minerals we need from just eating a healthy, balanced diet, supplements can only be seen as a luxury.  Check out the prices carefully.  Examine product ingredients and compare the big brands with the smaller brands.

5.  Is the company you’re about to purchase from reputable?  Does the company have a good offline presence as well as online?

To be healthy, children should aim to eat a variety of healthy foods every day. The growth and development of your children depends on it. By eating healthy, your children will have the energy they need to play, learn, concentrate better, sleep better and build stronger teeth and bones.

1. Enjoy a variety of foods. Serve up a healthy variety of foods each day. These include fruit and vegetables, legumes (such as dried peas, beans and lentils), wholegrain cereals, low-fat dairy, lean meat, fish and skinless chicken. Reduced fat milks are not suitable for young children under 2 years.

2. Shop healthy. If you haven’t got a healthy variety in your kitchen pantry or cupboard, you can’t put it on the table.

3. Go for quality, not quantity. Children’s serves may be small. It all depends on their age and appetite. Variety is the important ingredient.

4. Stick to three meals and two snacks every day. Growing children need to be fed regularly and often.

5. Begin their day with a healthy breakfast. It improves concentration and builds stamina.

6. Give your children choices. Offer kids a few healthy choices. For instance, ask if they would like an apricot or a plum, beans or broccoli, an egg or a tuna sandwich.

7. Lead by example. If the kids see you eating well and enjoying a wide variety of healthy foods they are likely to join in too.

8. Freeze in summer. Frozen fruits make great summer snacks. Try frozen grapes, bananas and mango wedges.

9. Keep warm in winter. Corn on the cob, baked potatoes, hot homemade popcorn, baked beans and stewed fruits can really hit the spot on cold
winter days.

10. Go for a dip. Set up a colourful vegie platter with a variety of dips or salsa.

11. Give your children water instead of juices, cordials and fizzy drinks. These drinks are full of energy and can often take away their appetite for other foods.

12. Set a sweet limit. Children don’t need sweet drinks but if you do include sweet drinks in your child’s diet, set a limit. That could be one small glass of fruit or vegetable juice, around 125ml, 1-2 times a week.

13. Make family meal times part of your routine. Whenever possible, sit and eat together as a family and have the TV turned off.

14. Lunchboxes that go crunch. Skip the chips. Fruit and vegetables in season make a great snack or lunchbox addition. Try corn on the cob, carrot and cucumber sticks, green beans, cherry tomatoes, celery, stone fruit, grapes or berries.

15. Family food – include everyone. Encourage children to enjoy the family foods and meals from an early age (about 12 months). Children will learn to eat what the family eats if they are given the same food and encouraged to try it.

16. Be persistent – you can’t afford to give up. It’s common for all kids to love a certain food one day and hate it the next. Just keep offering them healthy choices and they’ll soon be eating a wider variety.

17. If at first you don’t succeed then try, try again. Kids can be stubborn. But be patient. You may need to offer a new food 10 times or more before your child will accept it.

18. Get the kids in the kitchen. Encourage kitchen skills by having children make a sandwich or salad. Let them wash fruit and vegetables and make a simple green salad, tabouli or a fruit salad. Being involved will increase a child’s willingness to try new foods.

19. Be consistent. If your child isn’t hungry for healthy food, refrain from offering unhealthy substitutes. This will only encourage eating for reasons other than hunger.

20. Give them an encouraging word. Try not to force your child to eat. A much better technique is to praise them when they make a healthy food choice.

21. Try not to use food to punish or reward a child. A hug or a book is a much better alternative to food.

22. Hungry or not? Children sometimes eat when they’re bored, sad or lonely. Help your child to understand when they are eating for reasons other than hunger.

23. Let them make their own decisions. At the end of the day, it’s up to your child to decide whether or not to eat and how much. Your job is to offer healthy foods at regular intervals.

24. Call in an expert. If needed, get professional help to solve problems or keep the family motivated. Simply talk with your doctor, health practitioner or dietitian.
