If you’re avoiding grains due to a particular diet plan, or if you think you have to exclude grains due to gluten sensitivities, you may want to think again. HPRC has put together a table of grains (with and without gluten) and their basic nutrients to point out how nutritious grains can be. Even for those who are gluten-free or sensitive to gluten, the table shows there are plenty of healthy, gluten-free options to incorporate into your diet.
As the table indicates, whole grains are very nutrient dense: They contain fiber, vitamins such as niacin and folate (and other B vitamins), minerals such as calcium, iron, magnesium, potassium, manganese, zinc, and selenium, as well as protein and branched-chain amino acids.
A diet rich in whole grains has been associated with lower risk of Type 2 diabetes and cardiovascular disease. Paleo diet followers, as well as those who are following a gluten-free diet, need not eliminate whole grains from their diet. The benefits are vast, with many choices for a varied diet. For more information about whole grains, see the ChooseMyPlate.gov resource, “Why is it important to eat grains, especially whole grains?”
Bright orange fruits and vegetables contain performance-boosting nutrients and should be included as part of your colorful plate. You may just imagine oranges and carrots when you think orange, but orange includes vegetables such as pumpkin, sweet potatoes, butternut squash, orange peppers, and fruits such as mango (the most widely consumed fruit in the world), peaches, apricots, papayas, cantaloupe, and persimmon.
Vitamin C, fiber, potassium, and folic acid are just some of the powerful nutrients found in many orange fruits and vegetables. The bright orange color is due to the phytochemicals (plant compounds) carotenoids. Beta-carotene, which your body converts to vitamin A, gives yellow and orange vegetables their rich color and supports your immune function, promotes eye and heart health, and reduces the risk of cancer.
There are plenty of ways to incorporate more orange on your plate at any meal. For breakfast, add sliced orange, mango, peach, cantaloupe, or papaya to your cereal or in a homemade smoothie; for lunch, top your salad with chopped orange peppers or shredded carrots; and for a healthy version of fries at dinner slice sweet potatoes, sprinkle them with olive oil, salt, and pepper, and bake.
Do you think of white when you hear “make your plate a rainbow of colors?” Think again! White fruits—bananas, pears, white nectarines and peaches, and vegetables such as cauliflower, potatoes, garlic, mushrooms, onions, white corn, turnips, parsnips, kohlrabi, and jicama—are all full of nutrients and count towards your daily fruit and vegetable intake.
White fruits and vegetables contribute fiber, potassium, and magnesium, which most Americans don’t get enough of. Many white fruits and vegetables are also high in flavonoids, which give these plants their white color. Flavonoids are plant compounds shown to be anti-inflammatory and to help protect against heart disease and cancer. And allium, a component found in garlic and onion, has antioxidant properties and cardiovascular benefits.
Incorporating nutrient-dense white fruits and vegetables into your meals and snacks is easy. Add sliced bananas or pear to your oatmeal in the morning, or roast hearty root vegetables such as turnips, potatoes, and parsnips with olive oil, dried herbs, and spices for a delicious dish. Sauté onions and garlic to add flavor to pasta, rice, and stir-fry dishes.

Two new performance optimization documents are now available on the U.S. Army Public Health Command website. The Performance Triad Guide contains useful tools and strategies for optimizing your sleep, activity, and nutrition.
The Sleep section includes ten effective sleep habits, strategies for addressing sleep countermeasures (caffeine and supplements, for example), and considerations for a sleep management plan, including relaxation techniques.
Activity has tips for meeting your exercise goals, how to achieve the functional fitness required to succeed on the PRT, as well as information on injury prevention that includes safe running strategies and shoe selection.
Nutrition provides detailed information on nutrition for performance, daily carbohydrate and protein calculators, hydration, nutrient timing for peak performance, and dietary supplements.
The Performance Triad Challenge, designed for squad and unit leaders, provides information organized into six areas: the professional soldier athlete, physical dominance, cognitive dominance, emotional dominance, sustained operations, and social, family, and spiritual information. The beginning of each module features a leader’s guide for identifying target areas for improvement.
The Combat Rations Database, or “ComRaD,” offers up-to-date nutrition information on military combat rations, including Meal, Ready-to-Eat (MRE), First Strike Ration® (FSR), and Cold Weather/Long Range Patrol (MCW/LRP). Warriors, dietitians, food-service officers, and leaders can look up the complete combat ration meals, as well as their individual food components, and obtain information about calories, fat, vitamins, and minerals.
Check out ComRaD on HPRC’s website, and check back often to see new features that will be added in the near future, including a “cart” you can use to add and remove foods eaten and then tally up overall daily nutritional intake.
March is National Nutrition Month®, and this year’s theme is “Bite into a Healthy Lifestyle.” Sponsored by the Academy of Nutrition and Dietetics, this month-long nutrition education campaign focuses on showing you how to make informed food choices and promoting healthy eating and physical activity patterns to help you maintain a healthy weight, reduce your risk of chronic disease, and support your overall health. Be sure to check out their resources on food and health, and visit HPRC’s ABCs of Nutrition section too.
Fruits and vegetables provide many essential nutrients that benefit health and reduce risk of disease. Juicing provides an easy, convenient way to get more fruits and vegetables into your diet. However, most countertop juicers extract the juices from fruits and vegetables but leave behind the skin and pulp—where most of the performance-enhancing nutrients and fiber are found. To get the most from your fruits and vegetables, add the leftover skin, pulp, and fiber to other foods such as muffins, breads, or pasta sauces so you don’t miss out on the benefits they provide.
Juices that are mostly fruit-based provide concentrated sources of carbohydrates (“carbs”)—great for when your carb needs are high, such as before or after working out. However, drinking high-carb juices at other times of day can cause your blood sugar to “spike,” setting you up for a “crash” later on. Vegetable-based juices offer an appealing, lower-carb alternative, especially for the veggie-hater. In particular, juices from vegetables such as beets, carrots, and celery that are high in nitrates can naturally increase blood flow and reduce blood pressure—real performance-enhancers. If the flavor of vegetable-based juices doesn’t appeal to you, try adding a small amount of fruit to provide a touch of sweetness without too many carbs. And you can add low-fat yogurt or tofu for a protein boost.
Juicing is a great way to use up fresh fruits and vegetables that are a bit past their prime, reducing waste and saving you money. That’s important because juicers can be expensive, ranging in price from $50 to over $1000! A good-quality blender probably costs less than many juicers, doesn’t remove beneficial fiber, and might offer more versatility.
Keep in mind that fresh, unpasteurized juices can be a food-safety hazard. Harmful bacteria on your hands and on the surfaces of fresh fruits and vegetables can cause diarrhea, vomiting, and in some cases severe dehydration or other health problems. Thoroughly wash your hands, fruits, and vegetables before making fresh juices, and clean juicer parts with hot, soapy water when finished. Drink fresh juices the same day you make them and freeze leftovers in ice-cube trays to add to smoothies or thaw and drink another day.
Whether you get your fruits and vegetables in a glass or on a plate, make sure you’re getting enough for optimal performance. Use this handy calculator from the Centers for Disease Control and Prevention to find out how many you need each day.
Achieving and maintaining a healthy weight can be a challenge, especially when trying to juggle the demands of active-duty service, deployments, family, and life in general. Knowing that the next weigh-in is looming can be stressful and can sometimes lead to eating behaviors that spin out of control to become a life-threatening eating disorder. But even if you don’t have a classic eating disorder, you might have what is called “disordered eating.”
“Disordered eating” refers to eating foods or having eating patterns that can lead to serious nutritional consequences such as deficiencies in key nutrients and electrolytes. It can compromise a person’s strength and/or stamina and lead to more frequent illness or injury. This could happen to a Warfighter, spouse, child, or other family member.
Examples of disordered eating include emotional eating, binge eating, night eating, highly restrictive dietary patterns, and avoiding foods considered “bad.” Some individuals use over-the counter products such as weight-loss supplements or laxatives; others participate in excessive exercise as a means to control weight. What starts out as a way to lose a few pounds or tone up could become a serious problem.
If you’re wondering if you practice disordered eating, ask yourself these questions:
- Do you eat in secret?
- Are you terrified of gaining weight?
- Are you always counting calories/carbs/fat grams or some other component of food?
- Do you think your identity and self-worth depend upon your weight and body shape?
- Do you exercise a lot (maybe too much) to maintain your weight or appearance?
If you answered "yes" to any of these questions, you might have disordered eating. It’s important to get help before your problem becomes more serious than you can handle. Nutritional and emotional counseling from professionals—registered dietitians, counselors, and therapists—can help. Support from friends and family is important too. See the Academy of Nutrition and Dietetics for more information on disordered eating.
You probably know that fruit, vegetables, and olive oil are healthy foods for your heart, but what about chocolate? For hundreds of years, chocolate—more specifically cacao, the unprocessed cocoa bean—has been considered good for health.
Cocoa is in high in flavanols, plant compounds with antioxidant activity that can help prevent or delay damage caused by free radicals. These antioxidant-rich flavanols are linked to reducing the risk of cardiovascular disease. Some evidence has shown that cocoa can help lower blood pressure, LDL (“bad”) cholesterol and improve blood flow.
However, not all chocolate is created equal. In general, the less processing, the more flavanols. Pure, unprocessed cocoa has more flavanols than chocolate, which has sugar, fat, and other additives. Dark chocolate has more flavanols than milk chocolate and white chocolate. But eating enough chocolate products to reach the desired amount of flavanols could require hundreds or even thousands of calories. While all that chocolate may taste great, the extra sugar, fat, and calories are not heart healthy.
Enjoy a square of dark chocolate or a serving of cocoa as part of your day, but the jury’s still out on whether chocolate can really help your heart.
Beets are often overlooked in the produce aisle, but they have been gaining popularity for their potential cardiovascular health and performance benefits. This is because beets contain a high amount of nitrate, which improves blood flow to your heart and muscles. While the performance-enhancing benefits of nitrates from beets have yet to be fully established, there are many other reasons to include beets in your lunch or dinner menu. Beets are a great source of fiber, antioxidants, potassium, magnesium, folic acid, and vitamin C—all important nutrients to keep you at the top of your game.
If beets aren’t your favorite food, there are plenty of other nitrate-rich (and nutrient-rich) vegetables, including arugula, rhubarb, lettuce, celery, radishes, and spinach. Try eating roasted beets or a salad with dark-green, leafy vegetables two to three hours before your next workout. Keep in mind that eating a variety of high-quality foods is key to optimal performance, so for more information on proper fueling, see HPRC’s “An Athlete’s Guide to Everyday Nutrient Timing.”
