An interesting program for optimizing children’s health focuses on four specific behaviors that parents and children can use for health and wellness: Let’s Go!’s "5-2-1-0".
5—Eat at least five fruits and vegetables today – more is better!
2—Cut screen time down to two hours or less a day (no screen time for under age of two).
1—Participate in at least one hour of moderate to vigorous physical activity every day.
0—Zero sugar-sweetened sodas, sports drinks, and fruit drinks. Instead drink water and three or four servings a day of fat-free or one-percent milk.
For ideas about how to incorporate fruits and vegetables into daily meals, visit the MyPlate.gov KidsHealth website.
National Nutrition Month is still going strong, bringing lots of healthy eating information to the attention of Americans. The Academy of Nutrition and Dietetics is weighing in with their “Get Your Plate in Shape” campaign, which focuses on getting the right nutrition without too many calories. Their Eat Right website page offers snack ideas, recipes, weight management tips, and exercise nutrition advice.
The goal of National Nutrition Month is to remind Americans to eat healthy and choose foods with good nutrition. The FDA’s theme for 2012 is “Remember to Use the Nutrition Facts Label.” One tool you can use to help make good food choices is the Nutrition Facts label that appears on all packaged foods and beverages. To learn how to read labels, visit the FDA’s web page “Nutrition Facts Label Programs and Materials.”
The Military Health System (MHS) has developed a new obesity and nutrition awareness campaign for the Department of Defense (DoD). This campaign will reach all the services to help improve the health and well-being of Warfighters. Menu standards at military dining facilities will be updated, the environment of military facilities will be assessed, and healthier foods will be available in dining facilities and DoD schools. For more detailed information, see the news article and the MHS blog.
Learn how to make healthy choices about nutrition and physical fitness with information you and your family can instantly apply. HPRC's Family & Relationships section has a new area on family nutrition where you can find tips on how to help yourself and those around you—your parents, children, spouse, and friends—build and maintain healthy food habits. Find more information on interactive tools, family meal planning, military resources, and research findings.
Warfighters must be in excellent physical condition to endure a variety of physical tasks for extended periods. Healthy eating will greatly affect your physical performance. For good health and performance, eat the energy-providing nutrients (known as macronutrients)—carbohydrates, proteins, and fats. These foods supply fuel and are involved in many functions in your body. For detailed information on each of the macronutrients, see the Warfighter Nutrition Guide.
Whether you are at home or on operations, healthy snacking can sustain your mind and body so your performance is maximized. Keep high-nutrient foods on hand at home, while at work, or during night operations. For specific suggestions and tips on healthy snacking, see the Warfighter Nutrition Guide.
Eating disorders affect more women than men, and usually there is no single cause. Risks of developing an eating disorder can stem from genetics; biologic, emotional, and personality disorders, as well as family situations. Warfighters are not immune to these disorders and may even have a higher percentage than the general population. Having an eating disorder can significantly impact your performance. Not getting enough food or not eating healthy, consistent amounts of food means that your body is not being fueled optimally for performance. The University of Maryland Medical Center has put together a report on risk factors, causes, symptoms, diagnosis, and treatment for eating disorders as well as links to other helpful resources.
In order to optimize your health and physical fitness, you should consume a balanced diet as recommended by the U.S. Department of Agriculture. According to the USDA, you should limit consumption of sodas and trans-fat foods; replace solid fats with oils such as olive, canola, and safflower oils; reduce intake of added sugars and sodium; replace refined grains with whole grains; limit your alcohol intake; increase your intake of vegetables, fruits, and fat-free or low-fat milk; and replace some of the meat or poultry in your diet with seafood. More details and guidelines can be found on HPRC’s Nutrition domain, especially the recent articles on the new USDA MyPlate program and online availability of the 2010 Dietary Guidelines for Americans.
The Paleo Diet, also known as the Paleolithic or Caveman Diet, is based on the notion that by consuming what humans ate during the Paleolithic Era—wild animals, plants, eggs, tree nuts, vegetables, roots, fruits, and berries—we will be healthier, have lower disease risk, and live longer. Hunters/gatherers during that time had to rely on what was available and had no agriculture. But what are the implications of this type of diet for the athlete, let alone the average individual?
Foods that were grown and introduced after the Agricultural Revolution (roughly 10,000 years ago) are not allowed in the Paleo Diet. That means dairy and dairy products, grains, and legumes (beans, peas, and lentils) are excluded. Proponents of the Paleo Diet believe that we are “genetically programmed” to follow the diet of the hunters/gatherers. A specific book has been written for athletes who want to follow this diet, which accommodate athletes by allowing some carbohydrates: The authors present five stages of eating for the athlete to follow, based on the glycemic index (GI; how quickly food raises blood glucose levels). The stages are: (1) eating before exercise, (2) during exercise, (3) and 30 minutes after exercise, and (4) during post-exercise extended recovery and (5) long-term recovery. Low- to moderate-GI carbohydrates are recommended at least two hours prior to exercise. Sports drinks or high-GI carbohydrates are recommended for exercise lasting longer than 60 minutes. Immediately after exercise a recovery drink with carbohydrate and protein in a 4:1 to 5:1 ratio is recommended. Stage IV recovery foods (extended recovery) should be a 4:1 to 5:1 carbohydrate-to-protein ratio, with carbohydrates such as raisins, potatoes, sweet potatoes, and yams. Stage V recommends focusing on eating from the main Paleo Diet, with carbohydrates coming from fruits and vegetables. So one could argue that the Paleo Diet for Athletes is like most diets for athletes in that it requires carbohydrates. However, the Paleo Diet for Athletes is higher in protein and fat and lower in carbohydrates than what is recommended for athletes by most health professionals.
What we do know from scientific research is that carbohydrates provide the energy needed for endurance and resistance training, competitive athletic events, mental agility, and healthy living. Complex carbohydrates such as fruits, vegetables, whole-grain pasta, rice and grains, beans, and other legumes contribute to an overall healthy eating plan. By limiting consumption of some of these to only a brief time after exercise, the athlete runs the risk of not having enough fuel for the body, so the body will use protein for energy. Low-fat dairy products also contribute to a healthy lifestyle, providing much-needed calcium and vitamin D as well as probiotics. The Paleo Diet eliminates dairy entirely, even for athletes.
We also know from the scientific literature that during the post-exercise period, within roughly 30-45 minutes of exercise, eating a carbohydrate/protein snack, generally with a 3:1 carbohydrate-to-protein ratio, is essential to stimulate re-synthesis of muscle proteins and replenish glycogen (the storage form of carbohydrate). It doesn’t stop there: It is important to maintain glycogen levels in the muscle and liver to sustain all activities, especially over the course of several days. Eating high-carbohydrate snacks between training sessions is important to replenish glycogen stores. Carbohydrate intake recommendations for athletes are 6 to 10 g/kg body weight per day, or roughly 55% of daily calories from carbohydrates.
What’s the bottom line? Grains and dairy products are staples of modern-day society and provide essential nutrients to an overall healthy diet. By eliminating one or more food groups, you run the risk of missing important nutrients. And can we really eat as humans did during the Paleolithic era? Their life expectancy was about one quarter to one half of what ours is, and we benefit from research showing that eating a variety of foods over the course of time provides us with energy and the important vitamins and minerals needed to sustain us in daily activities and exercise.
