HPRC Fitness Arena: Nutrition
A hot trend in nutrition and dieting for some Warfighters is internal cleansing (or “cleansing” for short). Typical cleansing programs promise renewed energy, weight loss, and a fresh start—appealing offers following the rigors of a deployment, a recent change of duty station, or just life in general. Variants of cleansing programs may include “detox” (short for detoxification) diets, dietary supplement products, enemas, or some combination of these.
Although some detox diets emphasize eating lots of fruits and vegetables and drinking plenty of water, many detox diets lack certain vitamins, minerals, and other nutrients, and are dangerously low in calories. It might be difficult for a Warfighter to obtain adequate calories for optimal performance while following a typical detox diet.
Detox supplement products often contain herbs and other plant-based chemicals that have a laxative effect. Long-term use of laxative products can cause changes in the structure of your large intestine (colon) that might have serious health effects. Laxatives can cause dehydration, which impairs performance. In addition, according to the Food and Drug Administration there are concerns about dietary supplement products containing hidden active ingredients that can result in harmful effects.
Detox enemas, often marketed as “colon cleanse” products, cause the contents of the colon to be quickly expelled. Detox enemas contain a variety of substances, some of which can cause allergic reactions or electrolyte imbalances. Since many detox enemas are self-administered, there’s also the risk of tearing the inside of your rectum during the procedure, which can cause septicemia—a type of bacterial infection in the blood.
The guiding principle behind cleanse programs is that environmental and dietary toxins supposedly build up in your body, and you need to get rid of them to be healthy. However, there really isn’t any scientific evidence backing up these claims. Your body is designed to detox itself by getting rid of wastes through urine, feces, and sweat. The best way to take advantage of these built-in detox systems is to drink plenty of water (to produce more urine), get plenty of fiber from fruits, vegetables, and whole grains (to help pass feces), and exercise (to produce sweat)—a proven program to help you perform better and live a healthy life.
There’s hemp turning up in yogurt, cereal, milk, and other food products these days. What is hemp, and what are the service policies on the use of these food products? Read the Operation Supplement Safety (OPSS) FAQ to find out. Be sure to check back often as we add answers to other questions and topics in the OPSS section of HPRC’s website.

Have you heard about Go for Green®?
Go for Green® is a DoD-wide, joint-service food-identification program. It’s designed to help you easily identify the nutritional value of foods when you’re standing in line at the dining facility (DFAC) deciding what to eat.
Foods in DFACs are color-coded Green, Yellow, or Red to help you choose foods for optimal performance. When using Go for Green® in the DFAC, look for these symbols to identify “Green,” “Yellow,” or “Red” foods.
What do the colors mean?
Go: High-Performance Food
“Green” foods can and should be eaten everyday. These foods score high in nutrient density (the ratio of nutrients to calories in a food) and help you perform best. Most “Green” foods can be eaten without having to worry much about portion size.
Caution: Eat occasionally
“Yellow” foods are still healthy in small amounts but should be eaten less often than “Green” foods. How much and how often depends on your health and performance goals. Try to eat “Yellow” foods just some of the time.
Limit: Eat rarely
“Red” foods are meant to be treats eaten just once in a while. They have little nutritional quality but are often an enjoyable part of eating. Most people can have a few “Red” foods each week and still meet health and performance goals. Try to limit how much and how often you eat “Red” foods, and balance them with plenty of “Green” foods.
Although the Go for Green® program is geared toward use in the DFAC, it translates well to just about any setting—home, fast-food restaurants, even when eating MREs. Eating the Go for Green® way can promote a healthier, better-performing you. For more information, visit the Go for Green® website. Download the Go for Green® Guide for a handy reference.

The Performance Triad is well underway, and the Army has been closely monitoring the progress of soldiers at the three test sites (Joint Base Lewis-McChord, Fort Bliss, and Fort Bragg). Soldiers will be assessed on their knowledge, beliefs, and attitudes about the parts of the triad—sleep, activity, and nutrition. Triad staff is currently performing injury-risk assessments for the Military Power, Performance, and Prevention (or “MP3”) program as part of an ongoing process that helps get soldiers into physical therapy and strength-training programs to help reduce the number of “medically not ready soldiers.” You can read more about the Performance Triad in HPRC’s Total Force Fitness domain.
March is National Nutrition Month, and it reminds us about the importance of healthy eating. The theme this year is “Enjoy the Taste of Eating Right.” HPRC receives many questions that ask what the best supplements are for weight loss, bodybuilding, and enhancing performance. Our message is always the same: Focus on food first. Operation Supplement Safety (OPSS) has educational resources to help spread this message, including our “Real Food” poster and “Nutrition: Fueled for Fitness” brochure. Be sure to visit OPSS for infosheets, videos, and other educational materials for Warfighters, healthcare providers, and family members.
March is National Nutrition Month®, a month-long education campaign sponsored by the Academy of Nutrition and Dietetics to promote healthy eating. This year’s theme is “Enjoy the Taste of Eating Right.” It focuses on how healthy eating and tasty food go hand-in-hand. The Academy of Nutrition and Dietetics website provides lots of great tips, tools, and resources to help you develop healthy, tasty meals for you and your family. Also, visit HPRC’s Family Nutrition section for additional resources.
Carbohydrates provide our bodies with energy. “Good” carbohydrates—usually the complex carbohydrates such as vegetables, fruits, and whole grains—have more fiber. They also contain vitamins and minerals. “Bad carbs” include refined carbohydrates—foods made with white flour—and processed foods with added sugars. To find out more about eating the good carbs, read the Centers for Disease Control and Prevention information on carbohydrates.
Warfighters who eat a variety of fruits and vegetables are more likely to be at their optimal weight and less likely to develop diseases such as cancer, heart disease, and diabetes. But it can be hard to find a “rainbow” of fresh foods when it’s cold and gray outside and the summer farmers’ markets and roadside stands are months away. Fresh fruits and vegetables, while a great choice, can be expensive in winter and can spoil quickly, making it hard to keep them on hand. Frozen fruits and vegetables, on the other hand, might be just the ticket to make sure you get plenty of these nutritious powerhouses in your diet. Here’s why:
- Nutrition. The nutrient content of frozen fruits and vegetables is comparable to that of fresh ones. That’s because frozen fruits and vegetables are processed at their peak ripeness, while fresh ones might be eaten when they are either under- or over-ripe, when nutrient content is generally sub-par. (There are a few exceptions, though. The processing of frozen “cruciferous” vegetables such as broccoli, cauliflower, and Brussels sprouts destroys important enzymes that give them their disease-fighting capability. Opt for fresh versions of these veggies, and steam them lightly or eat them raw.) When purchasing frozen vegetables, choose versions without added salt and with minimal processing such as chopping or dicing for highest nutritional value.
- Cost. Although fresh fruits and vegetables are usually cheaper when they’re in season, their frozen cousins are your best bet in the off-season. If you’re on a budget, resist the temptation to purchase those meal-in-a-bag concoctions containing meats and/or rich sauces, though. You pay twice: first for the convenience and second for the calories. Instead, prepare frozen veggies in your microwave according to the cooking directions on the package. If you add some lean protein such as chicken or tofu, some spices, and a side of whole grains, you’ll have the makings of a great meal.
- Availability. The best thing about frozen fruits and vegetables is that they’re right there in your freezer. You can stock up on your favorites when they’re on sale and have a ready supply every time you cook—no excuses. Use them within three months of purchase, though, for optimal quality.
Fresh or frozen, fruits and vegetables are essential for optimal performance. Be sure you get enough every day.
Wanting some holistic strategies to enhance your performance? Check out the “One Shot One Kill (OSOK) Performance Enhancement Program” that shows Warfighters how to set up and manage their own performance-enhancement system. OSOK is designed not only to enhance performance but also to jumpstart Warfighter resilience. It builds on the skills that Warfighters already possess and then teaches new ones as needed.
There are two ways you can use OSOK: as an individual through “OSOK Solo” and as a unit/group through “OSOK-IP Unit.” Both highlight “10 Rules of Engagement” and provide seven core modules: Controlled Response, Mind Tactics, Performance-Based Nutrition, Primal Fitness, Purpose, Code, and Recharge. OSOK also provides self-assessment forms so you can track your progress over time.
