Vegetarians eat a plant-based diet that excludes meat, poultry, and fish. A well-planned vegetarian diet can meet all your nutritional needs, but you have to take special care to ensure you don’t fall short on a few key nutrients such as protein, vitamins, and minerals. Following a vegetarian diet while in the military can be an especially challenging practice, but you can stay healthy while doing so by following the information presented in HPRC’s InfoReveal on vegetarian diets.
Both deer velvet and IGF-1 have been in the news lately, and HPRC has received many questions about what these are and whether they improve athletic performance. Does deer velvet contain IGF-1? Read this OPSS FAQ about deer velvet to find out. To learn what IGF-1 is and whether it is banned in the military, read more in the OPSS FAQ about IGF-1. Be sure to check back often, as we add answers to other questions about ingredients in performance and weight-loss supplements and how to choose supplements safely.
March is National Nutrition Month, a month-long campaign sponsored by the Academy of Nutrition and Dietetics (AND) to promote healthy eating and physical activity. This year’s theme—“Eat Right, Your Way”—is aimed at helping people find personalized ways to meet the 2010 Dietary Guidelines for Americans. The theme acknowledges the fact that although food choices are influenced by culture, lifestyle, and personal preferences, you can still develop healthy eating habits—your way! AND’s website provides lots of great tips, tools, and resources to help you get started.
Coconut oil has a sweet taste that lends distinct flavor to foods, and it contains several saturated fats—something the 2010 Dietary Guidelines for Americans suggest we eat less of. That is because eating saturated fats has been linked to atherosclerosis (“hardening of the arteries”) and increased risk of heart disease.
Although coconut oil is highly saturated, it has different types of saturated fats. One of these—lauric acid—is regularly touted as having performance benefits. Lauric acid is referred to as a “medium chain fatty acid” (MCFA), and the body processes MCFAs differently than it does “long chain” fatty acids (LCFAs). Importantly, MCFAs are digested more rapidly than long chain fatty acids, so they are quickly absorbed and available as an energy source. Some research suggests MCFAs might help to optimize and maintain glycogen stores, thus extending endurance performance. Not only that, MCFAs are less likely than other fats to be stored as fat—a plus if you’re concerned about weight control. The performance claims surrounding MCFAs and coconut oil have not held up, and claims about their weight loss benefits need more research.
The American College of Sports Medicine and the Academy of Nutrition and Dietetics joint guidelines for Nutrition and Athletic Performance indicate that MCFAs do not provide any performance benefit. To date, only two studies have shown improvements in performance. On the other hand, MCFAs have been shown to increase the body’s use of “fats” as fuels, reducing food intake, so such products may promote weight loss. There just isn’t enough information available to make any scientific conclusions.
If you choose to eat coconut oil, do so in moderation for its unique flavor and texture, because its health and performance benefits are still open for consideration.
Solid fats are solid at room temperature, come mainly from animal products, and are high in saturated or trans fats. Examples are butter, milk fat, cream, stick margarine, shortening, and beef, chicken, and pork fat. Some saturated fats increase blood cholesterol levels in the body. Oils are liquid at room temperature, and come from many different plants, and are good sources of heart healthy unsaturated fats. Examples are olive oil, canola oil, safflower oil, corn oil, soybean oil, and peanut oil. Coconut oil, palm oil, and palm kernel oil are high in saturated fats and are considered solid fats. When using fats, replacing solid fats with unsaturated oils will provide essential nutrients to the diet and help lower blood cholesterol levels.

A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.
Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.
Wheat products such as bread and pasta are mainstays of our diets. However, some people are sensitive to gluten, a blend of two proteins found in wheat and other grains such as rye and barley. Three distinct conditions caused by gluten sensitivities have been identified: wheat allergy, celiac disease, and non-celiac gluten sensitivity.
Wheat allergy is more common in children than adults, and many children outgrow the condition. Symptoms include hives, itchy throat or eyes, and difficulty breathing. Wheat allergy can be life threatening and requires immediate medical attention—an especially serious consideration for Warfighters in the field.
Celiac disease is an autoimmune disorder that affects the small intestine. When a person with celiac disease eats foods containing gluten, his/her immune system attacks the small intestine, impairing the way the body digests food. Symptoms include bloating, gas, diarrhea, abdominal pain, lactose intolerance, and anemia. If not treated, celiac disease can cause neurological disorders, osteoporosis, and other autoimmune disorders such as type 1 diabetes. About three million people in the U.S. have celiac disease.
In non-celiac gluten sensitivity, or NCGS, a person is sensitive to gluten but—as the name suggests—does not have celiac disease. Symptoms include diarrhea or abdominal pain and vague, non-intestinal symptoms such as bone or joint pain, leg numbness, or skin rashes, making diagnosis difficult. About 18 million people in the U.S. have NCGS.
The only way to treat gluten sensitivities is to adhere to a strict gluten-free diet. Things to avoid include:
- Wheat, rye, and barley
- Flours made from wheat: self-rising flour, graham flour, cake flour, pastry flour
- Oats, unless certified gluten-free
- Communion wafers and matzo
- Soy sauce
Even if a product label says it is “wheat free” it might contain rye or barley. The FDA has established guidelines for labeling gluten-free foods.
Gluten-free foods can become “contaminated” with gluten in home kitchens so be sure to use clean tools for preparing and serving gluten-free foods, and designate appliances, such as a toaster, for use with gluten-free products only.
Many people with gluten sensitivities are deficient in calcium, folate, iron, and certain B vitamins. They should have their vitamin and mineral status monitored by a doctor.
Although following a gluten-free diet can be challenging at first, with a little practice it can become second nature. There are many gluten-free products on the market and many bakeries now offer gluten free selections. People who follow the diet typically experience significant improvements in their health and quality of life that make the effort worth the challenges. You can learn more about celiac disease and gluten-free diets from the Academy of Nutrition and Dietetics.
In the military, physical activity is probably part of your daily routine, but do you also have a post-workout strategy? Good recovery is just as important as the workout itself. “Recovery” can mean what you do—or don’t do—right after exercise. It also can mean taking a day off from working out altogether. Either way, it’s a critical component of your overall fitness program that can help prevent injuries.
First, it’s important to rehydrate and refuel after exercise to replace the fluids and nutrients lost during exercise, heal damaged muscles, and build more muscle. A combination of protein and carbs are the key for recovery. Some suggestions for post-exercise snacks are:
- Low-fat yogurt with fruit
- Trail mix
- Turkey wrap
- PB&J sandwich
- Chocolate milk (For more information about chocolate milk as a recovery snack, see HPRC’s Healthy Tip.)
Sometimes, after a particularly hard workout, you need a day of rest with no exercise. Listen to your body. If you have some lingering aches and pains that could worsen with exercise, take a day off. Sleep and rest are also important for proper recovery, staying fit and healthy, and achieving overall readiness and resilience. Make sure you get all the important components of your exercise routine in order to achieve peak fitness and keep injuries at bay.
Do you think nutritious foods are expensive? Think again. A cost-per-calorie comparison of the prices of fat- and sugar-laden convenience foods to the prices of nutritious whole foods showed the convenience foods coming up short.
A study conducted in a low-income area of Baltimore, Maryland, revealed that a diet based primarily on convenience foods from fast-food restaurants cost 24% more than a diet based on whole foods purchased in a grocery store. Of course, prices vary between seasons and geographic locations, but the message was clear: Don’t be fooled by “dollar menus” and “meal deals.”
Here are some more tips to stretch your food dollars:
- Meats: Buy lean cuts of meat, poultry, and fish on sale and freeze for later use. (Use freezer wrap for long-term storage.)
- Fruits and vegetables: Not only are fruits and vegetables less expensive when they are in season, the ones in season are freshest and have the best flavor. Take advantage of lower prices on apples in autumn, kale in winter, peas in spring, and strawberries in summer, for example.
- Processed foods: Cereal, low-fat pasta sauces, and other slightly processed foods can be healthful choices, but name brands can be expensive. Store brands are often excellent quality and typically cost less.
- Snacks and beverages: Opt for inexpensive (and healthy) snack choices such as popcorn, dried fruit, or peanuts. Milk and juice provide needed nutrients without the “empty” calories found in sodas and beer.
- Coupons, coupons, coupons: They’re like free money.
With a little time and planning you can provide your family with healthy, nutritious meals and save money.
Need a great post-workout beverage? Try drinking a glass or two of chocolate milk during the first 15-60 minutes after exercise to replenish glycogen stores and repair muscles.
Why chocolate milk? The carbohydrate-to-protein ratio in chocolate milk is roughly four-to-one, the best ratio for replenishing glycogen stores while providing adequate protein for muscle building and repair. One eight-ounce glass of chocolate milk provides about 200 calories. It provides carbohydrate, protein, electrolytes such as potassium and sodium, and essential vitamins and minerals such as vitamin D and calcium in an easily digestible liquid form that is inexpensive and readily available, and it tastes good! But be sure to choose heart-healthy low-fat versions.
For those who are lactose intolerant or allergic to dairy products, or for those who simply prefer a plant-based diet, fortified chocolate soymilk is a great alternative.
