Fruits and vegetables contain vitamins, minerals, and other nutrients that are essential for good health. That’s one reason why a plant-based diet that includes lots of fruits and vegetables can lower your risk of developing life-threatening diseases such as heart disease, diabetes, and some cancers. And when you pile on the produce, there’s less room for the unhealthy foods.
Dinner is typically the largest (and latest) meal of the day, and it’s a good opportunity to make sure that you meet your daily quota for fruits and vegetables. Here are five easy ways to work more produce into dinner.
- Roast vegetables. Roasting is a great way to let the deep, rich flavors of vegetables shine through. Bake cut vegetables at 375° F for 20 to 25 minutes or until they’re lightly browned. You can roast any vegetable — from mushrooms, onions, eggplant, and zucchini to tomatoes, broccoli, and carrots — so don’t limit yourself. Enjoy roasted veggies as a side dish or toss them into pasta dishes and other recipes.
- Poach veggies in low-sodium chicken broth and white wine. To poach, boil enough liquid to cover the vegetables. When it boils, add the vegetables. Turn down the heat to just below boiling and cook the vegetables for about five to seven minutes, until they’re brightly colored and tender-crisp. Add garlic, basil, or tarragon for a flavor bonus. To retain nutrients, keep a watchful eye on the pot, or set a timer so you don’t overcook.
- Smuggle fresh cut vegetables into main dishes. Try adding mushrooms, peppers, zucchini, onions, or carrots into pasta sauce, casseroles, soup, stews, scrambled eggs, and chili.
- Have a salad with dinner most days. Stock your salad with dark green leafy lettuce and toss in petite peas, tomatoes, onions, celery, carrots, and peppers. As an added benefit, starting meals with a salad can help you consume fewer calories at the meal, as long as the salad is no more than 100 calories. A healthful salad consists of about 3 cups of dark green lettuce, 1⁄2 cup carrots, a tomato, 1⁄4 cucumber, and 1 1⁄2 tablespoons of low-calorie dressing.
- Choose fruit — fresh or frozen, stewed or baked — for dessert. It all counts toward your daily produce quota. Dried fruits are healthy but high in calories, so eat them sparingly.

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.

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
Vitamin 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
-
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 story of a four-year-old boy in India who has been running distances of up to 60 kilometers has led to a lot of discussions, including among the Take The Magic Step® team. We spoke to Dr. Henning Ohlert about appropriate exercise for young children, as well as about some strategies for parents to deal with this issue.
Dr. Ohlert, 46, is a lecturer of training science at the University of Potsdam. He was a professional athlete for ten years, and as a 23-year-old ran the 800 meters in 1:45.9. He is working on a long-term study of motor skills and development of ten-year-old children.

How much exercise can a child cope with?
Over the years, our attitude towards children’s capabilities has changed tremendously. Basically, you could say that children are “little champions of endurance.” The big advantage of children is that they stop what they are doing automatically when they feel that they are getting tired and reach their physical limits. If children are tired out during playing, they simply take a break, and once they have recovered, they get active again. I think that you cannot do anything wrong with children-you just cannot challenge them physically in the wrong way. They know how to adjust themselves, and will utter their disapproval when it gets too much for them. And this disapproval should be respected.
What you have to watch out for with children, however, is problems with their thermoregulation; that is, the loss of body warmth during physical activity. Children get red faces when they are playing, bouncing around or playing sports. The body warmth which develops causes fast panting while breathing. The reason for this is that their perspiration system with does not function as that of an adult yet. That’s why you have to be careful to prevent children from overheating. In general, however, children have quite a sensitive feeling for the right proportion of activity and rest. It is highly dangerous, though, what is demanded of the little boy in India.
How can parents tell what and how much they can expect and ask from their children?
I believe you can ask more from children than most parents would think. You can judge by certain subjective criteria if a physical activity is enough: the color of the skin (for example, if the paleness of the skin is extreme), the frequency of the breath, the heart rate as well as the quality of movements. You will realize pretty quickly that movements seem to become uncontrolled and the way children fall changes. These are clear indications for the necessity of a break.

At what age should children start to train on a regular basis?
In order to answer this question, you would have to define the term “systemically organized training” first. I think that until a child has reached the age of eight, we shouldn’t call it training. There is nothing wrong with daily exercise or physical activities. Children should be active in various non-specific ways and thereby gain a broad range of experiences. This is the best prerequisite for successful involvement in sports later on.
Is there such a thing as unathletic children?
In my opinion, there is no such thing as unsporty kids. At times someone gets called “unathletic” just because he is judged by certain skills and abilities. It is just normal, however, that you are not able to do things which you have never done or practiced before. Often you get also judged by your family background. But just because your parents consider themselves unathletic, it does not necessarily have to mean that the son or daughter is as well. Every child is athletic. The question is only if she is athletic enough to become a champion.
Don’t children have a natural urge to move?
Absolutely. Unfortunately, this urge is lost throughout the ontogenetic development. At puberty, this urge to move decreases. This is when young athletes often lose interest in their sport and don’t show up for training anymore.
Should parents try to intervene?
It would not be good if the enthusiasm for the sport got completely lost. It is normal and should be tolerated that there are phases of less motivation. You should still try to talk to your child, his or her coach and friends about the situation, options and possible wasted opportunities.
Children tend to change their enthusiasm for different things quite quickly. Today they are playing tennis, tomorrow they want to become a professional swimmer, the day after tomorrow a famous basketball player. Sometimes they are not sure at all. Should children do several kinds of sport or should they better concentrate on one?
I strongly recommend that children experience a rather broad range of physical activities. I assume that not every child should be trained to become a Davis Cup player. Instead, most children will just want to play tennis for fun, or they just want to go inline skating, running or play soccer. I am a great supporter of children practicing a variety of sports.
Is it naive to believe that children will be grateful one day if parents put some pressure on them and force them to keep up a certain sport, hoping that they will be successful and the sport turns out to be the right one for the child?
This wish or hope might be honorable, but children think differently. Children think very emotionally, and are not as rational as adults are. The reasons why children give up on something are not easily understood. A little bit of pressure might not be wrong. It is a great achievement, however, if children discover themselves what they like.
Should parents tell their children which expectations they have regarding their sporting performance?
Parents’ expectations should not put too much negative pressure on the children. There is a lot of evidence in pedagogy that children fail just because their parents were asking too much of them. Children often act paralyzed if they are put under too much pressure. Then they are often criticized for failing mentally, but no one realizes how much pressure has been put on them: “You have to do this, you have to do that!”
Parents have to learn to judge their children’s mental condition and figure out how they can teach them ambition and determination. As a matter of fact, a runner participates in a race to get to the finish line among the best and not far behind the first ones. Consequently, you can, of course, tell your children that sport is often about being better and faster than others. This should be done sensibly, however, and without any pressure. It is nearly impossible to get children’s enthusiasm back if you have put them off doing sports once and if sports have become a trauma for them. This is proven by scientific research. The next chance you get to convince them of doing sports again is when they have grown up and when stress at work and an unhealthy diet have caused health problems and the cardiologist tells them, “You have to get moving, you have to exercise!”

On the other hand, children are often highly motivated when their parents watch them at training or competitions.
It is obvious that children are extremely motivated when they realize that their parents fully support what they are doing. At some stage, however, their own motivation will become so high that they don’t need their mother’s or father’s support anymore. But even professional athletes are more motivated when their parents are in the stadium or along the race course, no matter if in tennis, soccer or running. The question is just how parents react to their children’s failure. It is important that you find out together-maybe even with the coach-where mistakes might have been made and how you could adapt the training. Children have to feel that you support them and don’t give up on them.
What should parents do if their child suddenly, after two years, does not like judo anymore and would rather want to do athletics or tennis? Should parents demand that their children continue doing what they have started to do and not to give up on something just because it is no fun at the time?
I don’t find it too bad to change from one kind of sport to the other. You should have a conversation and clarify why they don’t like the sport they used to do anymore. There are certainly understandable reasons for it. And if they are not understandable, you still should not act against your child’s wish.
What should parents do if they recognize sporting talent in their child, but are not sure if they want to support it?
If someone thinks his child has got talent in some area which is illustrated by being better at something than other children of the same age, I would recommend approaching a sporting club close by and asking if there are facilities to support this talent specifically. I don’t find it very good to place children in “talent factories” far away from home where they waste a lot of time traveling to and from the place. Children should be able to pursue their training without many hassles. If they further develop and prove their talent, there are more opportunities of support in young adulthood, such as elite sporting schools or scholarships.
And vice versa: How are mothers and fathers to act if children desperately want to become professional athletes, but just seem to lack the talent?
I would still give the child the same chances, as eventually the “moment of truth” will show if the child is as good as she thinks she is. In cases of constant failure, however, you should be honest with your child, and tell him that another kind of sport might be more suitable for him. There are a lot of children who change to another kind of sport after the advice of a friend or parents and who have become really successful at it. Children who are motivated and ambitious should initially do what they prefer and should try things out.
If parents for some reason think that they should apply sanctions against their child-maybe because of bad marks at school-are prohibiting going to training and doing sports reasonable disciplinary measures?
I find prohibiting sports as punishment pedagogically not wise. Children have a natural urge to move and to play in order to cope with stress and emotions, and you cannot just switch this behavioral pattern off. If they are aggressive at school, they will be aggressive at sports, too. But particularly here, those negative emotions can be turned around into positive ones-through the pure movement, through the contact with the coach, through the group dynamics in team sports where bonding and camaraderie are crucial.

Our children are our future—and understanding and supporting their natural yearning for physical activity will help lead them to a lifetime of happy and healthy living. If we joyfully teach them how to include healthy exercise from the early stages of their development, we will be giving our children a gift that will endure throughout their lives.
Among the many benefits are physical fitness, confidence and stronger self-esteem, more energy, better memory, and simply a good feeling about themselves—and they are easy to achieve. Our Take The Magic Step® team is as concerned as many of you about the growing problem of childhood obesity and the lack of exercise in their lives. Whether this obesity and inactivity is caused by the popularity of video games or the declining hours of physical education in schools, it is a wake-up call for everyone. Happily, there are ways of reversing this growing trend and helping our children to enjoy daily exercise and outdoor activities, which they love given the opportunity.
Our “Children’s Fitness and Health Program” is geared towards parents and educators, and focuses on creative ways to incorporate exercise into our children’s everyday routine. Outdoor games and playful workout routines can be the tools that instill lasting joy of exercise. I was so lucky that I was introduced to, enjoyed and benefitted from these activities during my childhood. It created in me an appreciation and understanding of the complex benefits that fitness and exercise can add to a person’s wellbeing. Over the years I’ve been fortunate to share this lasting experience with many children and young adults. (I hope you find additional information in the “Families” section of this Web site).
To emphasize once again the importance of exercise, I have put together some of the health benefits an active child can expect.
Exercise Improves Physical Health
Long-term health benefits of exercise are:
- A stronger immune system! The body’s ability to fight disease is improved. Children are less prone to colds, allergies, and diseases, including cancer.
- A reduction of type 2 diabetes by increasing insulin sensitivity and improving carbohydrate metabolism.
- A lower blood pressure and an improvement of the child’s cholesterol profile.
- A strengthening of the entire cardiovascular system, including the heart and lungs. The heart develops a higher “pump-activity” while the child’s heart and lungs are strengthened, supporting the prevention of heart disease.
- Children are less likely to become overweight and will have better control of their body fat. Overweight children are able to reduce their body weight and body fat due to the physiological effect of burning fat while exercising.
- Children develop stronger bone structure and muscle structure.
Active children enjoy additional health benefits, because:
- Exercise increases the blood flow to all body tissues, including the brain. Greater blood flow transports more oxygen and nutrients to the body’s cells.
- Active children improve their body’s ability to absorb oxygen through aerobic exercise. Due to the increased oxygen in their body’s cells they feel more energized. More oxygen translates into more energy!
- Increased blood flow promotes the body’s transportation of the byproducts of metabolism and toxins back from the cells for elimination, recycling, or further use elsewhere. Children who exercise feel fitter and more energized because of their body’s ability to detoxify.
- Active children breathe better and sweat more. Breathing and sweating are great ways to detoxify the body and help it keep itself “clean.”
- Children increase their over-all fitness through exercise(1).

- Exercise enhances the brain’s metabolism. Studies show that active children have improved memory as a result of better brain function!
- Moderate, fun-oriented exercise literally burns off excess harmful hormones and, at the same time, increases the release of beneficial ones. One of the beneficial hormones acts as neurotransmitter for establishing new memories.
- Active children have the ability to concentrate much better, even at the end of a long school day.
- Studies report that exercise decreases anxiety, reduces depression, and improves mood and outlook in children. In addition, their quality of sleep is improved.
Perhaps most importantly, physical activity develops children’s self-esteem and confidence. Their ability to overcome difficult situations improves and they simply enjoy a better, sunnier outlook on life.
To parents and educators: Your efforts to encourage our children to exercise more and instill in them the wisdom of good nutrition and a healthy lifestyle will yield years of dividends in these young people’s lives. (… and the benefits mentioned are for adults too.)
To YOU CHILDREN: I wish you enjoyment of all your outdoor activities, your exercise, and your school! We are always with you!
