HPRC Fitness Arena: Nutrition
Dietary data from the National Health and Nutrition Examination Survey (NHANES, 2005-2006) for children between ages two through 19 suggest that children may not be drinking enough water for optimal health. The study also found that children and adolescents may be getting as much as two-thirds of their total water intake with their main meals. Try replacing non-nutritious beverages like sodas with nutritious beverages (or better yet, plain water) at meal time. This could have a positive impact on the diet, weight, and health of your children.
According to a recent article in Wired.com, the Pentagon has taken an interest in monitoring troop nutrition. In the article, it is reported that the Defense Advanced Research Projects Agency, better know as DARPA, will be hosting a Point of Use Nutritional Diagnostic Devices Workshop.
DARPA outlines that the workshop's aim is to "bring together members of the nutrition community and the point of use device community to review the current state-of-the-art in nutritional assessment technology and to identify the research and development needs for point of use devices that perform assessments of nutritional status of our Warfighters".
Wired seems to be giving greater coverage to Warfighter fitness as of late – last month they featured an article on the influence of high intensity fitness programs in the military.
A new study shows that people who read food labels tend to have healthier diets than those who don't pay attention to this information. Although the use of food labels will not necessarily change behavior, they do help you make informed decisions, because they provide important information about the product. Make an effort to read food labels. It may help you eat better and be healthier!
The Federal Trade Commission (FTC) recently filed a complaint against POM Wonderful products due to deceptive advertising. POM Wonderful has claimed that its products will reduce (or treat) heart disease, prostate cancer and erectile dysfunction. The FTC says that these claims are not supported by scientific research.
So, what’s a health claim and what’s considered acceptable advertising as such?
A health claim statement has to have a food substance, food, or dietary ingredient, and a health condition or disease. The Food and Drug Administration (FDA) has approved certain health claims that, based on scientific evidence, show a link between a food or supplement and a health condition or disease. Health claims cannot state that a food product or supplement can treat or cure a disease. It may claim to minimize a disease risk; for example, a product advertised as low sodium can state the approved claim that “diets low in sodium may reduce the risk of high blood pressure, a disease associated with many factors.”
Health claims shouldn’t be confused with structure/function claims. These claims do not have to be approved and reviewed by the FDA, yet they must be truthful in stating that a substance maintains structures and/or functions of the body. We see these claims on many fiber-rich products, like “fiber maintains bowel regularity,” or a dairy product stating that “calcium builds strong bones.” Unlike health claims, structure/function claims cannot be linked to a health-related condition or disease. Also, an important point to keep in mind: if a dietary supplement label makes a structure/function claim, it must also state this disclaimer: “This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”
There are also nutrient content claims. These describe the amount of a nutrient in a product. Descriptions such as free, low, high, and rich in are used, or other terms that describe the nutrient content to that of the content in another product, such as reduced, lite, less, or more.
Manufacturing companies want consumers to buy their products. We, as consumers, must be savvy as we try to choose products that are healthy for our families and us. False health claims are used on food products as well as dietary supplements. They claim to help us lose weight, cure diseases, and prevent memory loss. The FDA has not approved claims that focus on the treatment of diseases. They have, however, set forth regulations to authorize health claims after the scientific evidence has been presented and reviewed.
Eating with your family around the table is an effective way to bond, communicate, and even eat healthier! So, turn off the television and put all cell phones away during dinner time to improve family dynamics and health.
Protein powder supplements are a popular source for packing on muscle. The September 27, 2010 edition Health section of the L.A. Times contains an article that poses the question of how much supplements, if any, should one use in building muscle mass?
It may be hard to avoid the convenience of fast food since it’s inexpensive, tasty, and well...convenient. But with that convenience often comes an overload of calories, fat, and sodium.

The September 27, 2010 edition of the Wall Street Journal 's Health Blog reports that food giant Nestle' is looking to expand their stake in "functional foods" - foods that might prevent diseases. According to the article, the company is investing over $500 million into research in order to get a foothold into the functional food market. This move comes on the heels of yesterdays news that the Foot Trade Commission (FTC) is suing the maker of a popular pomegranate fruit drink, POM Wonderful LLC, in a widening effort by the government to clamp down on food ads that tout specific health benefits.
It remains to be seen how this will play out.
According to the press release, Nestlé will create a wholly owned subsidiary, Nestlé Health Science, as well as a research body, the Nestlé Institute of Health Sciences, “to pioneer a new industry between food and pharma,” the company said in a statement.
The September 27, 2010 edition of Army Times has an article that focuses on to the Army's new focus on training soldiers to eat and drink healthier items that not only prepare him for strenuous physical activity, but also fuel him throughout the endeavor and aid in his recovery afterward.
Sleep requirements vary slightly from person to person, but in general, most healthy adults need at least eight hours of sleep each night to function at their best. Food fuels our way through the day (can give you the necessary energy to pull you through the day), but did you know that food also has an effect on how we sleep? Watch what you eat in the course of a day – particularly in the hours before you go to bed – if you want to optimize your sleep at night. We give you some tips below on the best foods to eat to help you sleep soundly, and those to avoid if you have trouble resting at night.
Foods to avoid before bed:
- Caffeine: Caffeine can cause sleep disturbances even many hours after drinking it. Some people find there’s a cut-off time for their bodies – caffeine before that time won’t affect their sleep, but anything after, say, 2:00 p.m. can cause problems with their sleep. Caffeine is found in coffee, tea, and chocolate, among other foods.
- Alcohol: Some people think of alcohol as a nightcap to help you sleep better. While it may help you get to sleep faster, it also reduces sleep quality by waking you up later, in the middle of the night. A glass of wine before bed should be fine; several stiff drinks are not.
- Big or heavy meals: Fatty food takes time to digest and may keep you from getting to sleep. Spicy and acidic foods at night often cause stomach problems and/or heartburn. Try having an earlier dinner and avoid heavy, rich foods within two hours of when you’ll be going to bed.
- Liquids: Caffeinated drinks act as diuretics, resulting in frequent nighttime trips to the bathroom, and drinking too much water or other liquids close to bedtime also increases your trips to the bathroom in the night.
- Sugar: Anything too sugary, like many desserts or nighttime snacks are, can interfere with your sleep.
Best foods before bed:
- Bananas: Bananas contain large amounts of tryptophan, which triggers the release of melatonin and serotonin in our brains, helping us relax.
- Dairy: Dairy is also a good source of tryptophan, especially combined with some carbohydrates, like oatmeal. A warm glass of milk or a small bowl of oatmeal should help you sleep.
- Turkey: Another good source of tryptophan. Think of the post-Thanksgiving turkey slump many of us experience! Combined with whole-wheat bread in a small sandwich, this is a recipe for a deep, relaxing sleep.
Quality sleep is essential to our health. To start sleeping soundly, try some simple modifications to your diet and see if it helps you.
