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

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.

When you decide on your favorite summer workouts—we discussed a few fun options in Part I—you can move on to organize everything so you stay healthy and well-hydrated during your fitness routine.

First of all, add extra care to how you prepare for your workouts. Make sure you are properly hydrated beforehand. Drink small amounts of water frequently, beginning two hours before you go out. I would not necessarily drink too much for 20 to 30 minutes prior to your start, though, because it can make you need to “go” while working out.

If you plan to work out for more than one hour, you might want to run with a water bottle belt, as many athletes do. You also could leave one or more water bottles on the course. If you decide on that strategy, it is best to stay on a loop course. This gives you a chance to replenish every few miles. And, if you want to be absolutely safe, ask a friend to join you on a bike. For bikers, use both your water bottles, and stay ahead of the game by stopping at any convenience store or gasoline station to fill-up your bottles before you need them again.

Listen to Your Body, Stay Healthy

Nothing is more important than listening to your body. If you do not feel well, please be very cautious. Before, during, and after your workouts, the first signs of a possible problem might be heavier breathing, an elevated heart rate, or losing concentration. Consider wearing a heart rate monitor—it can caution you before you run into trouble.

When you feel unwell, admit it to yourself early on and get out of the heat right away. Cool off with a cold towel, use ice cubes, and hydrate! Please, do not wait to see a physician if you do not feel better immediately. Be familiar with some of the early warning signs of overheating: dizziness, fainting, fatigue, hot skin and followed by chills, lack of perspiration, feeling thirsty, and elevated heart rate. If you stop sweating, you most likely are very dehydrated(1).

Also be careful after your workout. Take a dry shirt to put on after your run, and always take some fluid to drink. If you feel cold—even in summer, for example when you come from outside into an air-conditioned room while still wearing your wet workout clothes—change immediately into dry clothes. It may be summer, but you need to stay “warm” after your workouts to avoid weakening your immune system and maybe getting a cold.

For adequate protection, sunscreen, glasses, a summer hat, and a rain jacket are always good to have close by.

Hydrate Well Throughout the Day

It can be very warm and dry during the summer, so make sure you stay cool and hydrated at all times. There are some guidelines I would suggest, and one of my favorite is to keep a bottle of water or a sports drink close by. This will remind you to drink and get replenished with small amounts continuously and evenly spread out throughout the day.

Hydration is critical for many body functions, such as digestion, regulation of body temperature, and the circulatory processes that bring nutrients to the cells and transport waste from them. This is even more understandable when considering that our bodies are up to 75% water in total, depending on age and build, with blood being 83% water and the brain being 75 to 78% water. These are the levels when each of those organs work best(2).

When you get dehydrated, every cell in your body suffers, causing you to feel less fit and fatigued(3). This puts more stress on your body and makes you more prone to illness and disease. And you can be at risk of overheating, which can have terribly serious consequences—including being life-threatening.

For proper hydration, start with juice from a fresh squeezed lemon with lots of water first thing in the morning. It is good for re-hydration after your night’s sleep and also will help your body to detoxify.

And as mentioned earlier, drink enough before, if possible during, and right after your training. It is best to replenish within 30 minutes of finishing your workout—the so-called “recovery window.” I like to eat a big slice of water melon right after my training, it is a great source of water, antioxidants, and easily digested carbohydrates. In the following article “General Guidelines,” you can find more information on this topic.

A Few Thoughts on Summer Nutrition

Many people like to adjust their nutrition and take advantage of everything that is fresh and more available in the summer, like tasty fruits and vegetables. It is berry season—maybe you are lucky enough to be able to pick your own on a berry farm. Eat food that has high water content like melon, citrus fruits, berries, and vegetables.

Diluted fruit juices with 1 part juice and up to 2 parts water can help you to stay hydrated. The juice from sour cherries, for example, has many health benefits and can even support faster strength recovery for runners.

You also can try the many different kinds of unsweetened iced teas. My favorite flavor is mango.

Enjoy what you eat and make it tasty. Add some cool summer nutrition like different kinds of smoothies. Depending on the amount you make, they even can be served as an entire meal. Just add water, berries (like raspberries and blueberries), banana, whey protein, and some ice cubes into a blender. Mix it and enjoy. Or try a variation with mango or pineapple. And for more health benefits, add a teaspoon of ground flaxseeds.

There also are many delicious salad creations with great dressings. You could try a variety of citrus dressings. Other choices of salads include my favorites—fresh cucumber salad with dill and onions or a tomato salad with olives, feta, and basil.

Sashimi and sushi can be delightful lighter dinner fare when well-portioned. And when you prepare your meals, add more vegetables than pasta or potatoes. And how about cold summer soups like water cress and gazpacho?

And for all you BBQ lovers, here are some thoughts on “Healthier Grilling.” I hope you can enjoy many relaxing summer evenings with your family and friends.

Good luck for your summertime fitness!

Food safety outdoors
Food poisoning is a real risk when taking food outside the home. Taking food out of its regular environment such as the fridge, freezer, pantry or clean kitchen for long periods of time can mean a greater risk of contamination. Take extra care with packed lunches for work and school, picnics and eating outdoors, especially in warm weather.

Eating outdoors and the risk of food poisoning
Eating outdoors is a great way to enjoy the hot weather, but it can bring added risks because:
• Bacteria grow more easily when food is stored in the ‘temperature danger zone’ of between 5 °C and 60 °C.
• Facilities for cleaning and hand washing may be inadequate, and clean water is not always available.
• Food can be exposed to contamination from insects, pests, animals and dust.
High-risk foods Food poisoning bacteria grow more easily on some foods than others.
These high-risk foods include:
• Meat
• Poultry such as chicken and turkey
• Dairy products
• Eggs
• Smallgoods such as hams and salamis
• Seafood
• Cooked rice
• Cooked pasta
• Prepared salads like coleslaws, pasta salads and rice salads
• Prepared fruit salads.

Some people are more at risk
Some people are more at risk of getting food poisoning than others. Special care should be taken with their food. Vulnerable groups include:
• Pregnant women
• The elderly
• Young children
• People with chronic disease.

Home barbeques and outdoor cooking
Some practical hints for keeping food safe to eat when you have a barbeque at home are:
• Keep the meat in the fridge until you are ready to start cooking.
• Store raw meats and poultry separate from cooked items, and underneath other food so that raw juices do not contaminate other food.
• Cook food to at least 75 °C. Use a meat thermometer to check the final temperature. Using
a thermometer is the best way to ensure that meats are properly cooked. If you don’t have
one, you should cook poultry until the meat is white – there should be no pink flesh.
Similarly, if there is no thermometer, cook hamburgers, mince, sausages and other meats
right through until any juices run clear.
• Never buy cracked or dirty eggs and always thoroughly cook any food made from eggs.
• Use a clean plate for all cooked meats – don’t re-use the same plate or container that held
raw meats. Don’t use the same equipment used to cook raw food (such as tongs or forks)
to handle cooked food.
• Take salads, pates, dips and other perishables outside only when required, and return
them to the fridge when that part of the meal is finished.
• Throw out any high-risk food left in the temperature danger zone for more than four hours.
Don’t put it in the fridge and don’t leave it for later.
• Cover food and keep birds, insects and animals away from it.
Preparing food for outdoors
When planning a picnic, making packed lunches or preparing for any other occasion where you are
eating away from home, be aware of the basic food safety rule – keep hot foods hot and cold foods
cold. You should also:
• Store any raw meat in an insulated cooler, away from other food.
• Cut and prepare all meats and salads beforehand to reduce the need to handle foods when
you are outdoors.
• Place containers with raw meat or other high-risk foods into separate leak-proof containers
and then into a cooler.
• Make sure all cooked foods are completely cooled before you pack them in the cooler.
• Use plenty of ice or cold packs around the food. Frozen drinks can serve as icepacks,
especially in packed school lunches.
• Travel with the cooler on the floor of the car, out of sunlight. Cover the cooler with a
blanket for extra insulation.
Camping food safety tips
Perishable foods are generally unsuitable for camping unless you have access to a fridge. It is best
to take dry, UHT and canned products. Other tips for camping include:
• If you want to take some meat with you, frozen meats can be stored in a cooler with ice
bricks for up to two days and pre-cooked meals, such as frozen stews, for up to one day.
• Cover the cooler with a wet bag to promote evaporative cooling.
• Divide the food into meal-size portions and pack it according to when you plan to eat it so
that you can get what you need quickly.
• Make sure you cook or heat all food well, to at least 75 °C.
• Boil drinking water before use, or use disinfecting tablets.

General cleanliness tips
Cleanliness is always important, but it’s especially important when you’re preparing food outside the home.
Remember to:
• Wash your hands before and after handling raw foods. Wash your hands with clean water and soap, and dry them with clean towels or disposable towels.
• Consider using disposable wipes or a hand sanitiser if there is no safe water.
• Keep the outdoor area or campsite as clean as possible.
• Keep food sealed and covered – birds, insects and animals can be a source of food poisoning bacteria.
