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.
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.”
You may know that calcium and vitamin D are important for healthy bones, but do you know that magnesium plays an important role too? People who eat enough magnesium in their diet tend to have higher bone mineral density (a measure of bone strength) than those who do not. Not getting enough magnesium can put you at risk for osteoporosis (weak, fragile bones).
So make sure you get at least the Recommended Dietary Allowance (RDA) for magnesium, which is 400–420 mg for men and 310–320 mg for women. According to the Institute of Medicine’s Committee on Military Nutrition Research, only 30% of military personnel meet or exceed the recommendations. However, this doesn’t mean you need to start taking magnesium supplements. You can easily get enough magnesium from eating a variety of magnesium-rich foods in each food group:
- Vegetables—dark green, leafy vegetables such as spinach
- Fruits—bananas, avocados
- Protein—beans, legumes, nuts, and seeds, as well as fish and seafood
- Grains—fortified cereals and whole-grain bread, rice, and pasta
- Dairy—milk, yogurt, and soymilk
As an added benefit, many of these foods are also rich in other nutrients, such as calcium, that help keep your bones strong. For additional information, see the Magnesium Fact Sheet from the Office of Dietary Supplements. And for information on other nutrients related to bone health, see HPRC’s Eating for healthy joints and bones.
You’re watching what you eat. You’re exercising regularly. You’re doing everything right. But for some reason, your weight-loss goal is just out of reach. It seems those “last 10 pounds” are often the hardest ones to shake! Fortunately, with continued effort and persistence, you likely can achieve your weight-loss goals.
If you haven’t done so already, be sure to speak with your healthcare provider or a registered dietitian to make sure the goals you’ve set for yourself are realistic, healthy, and sustainable. After that, it’s time to get to work.
Go back to square one. That is, make sure you’re as careful about what you choose to eat now as when you first started on your weight-loss journey. Sometimes we lapse into old habits over time and start “allowing” unhealthy choices to creep back into our diet patterns. Keeping a food diary will help you keep track of what you’re really eating. And don’t forget to watch your portion sizes.
Be a weekend warrior. Many people find it harder to make healthy choices on the weekend—tailgate parties, family celebrations, and road trips all offer opportunities to “slip.” But eating healthy is a full-time job, so it’s important to plan ahead: Take a low-fat dish that you’ve prepared and choose restaurants where you know you’ll have healthy options available.
Stand up for yourself. Literally. Standing, rather than sitting, can burn as many as 200 to 300 calories per day and can help prevent many types of disease. Find as many opportunities in your day to stand, walk, and move as much as you can. Check out HPRC’s blog about “sitting disease” for more information about the risks of sitting too much.
Shake things up. Varying the type and intensity of your exercise is a great way to challenge yourself and prevent boredom—and can make a big difference toward achieving your goals.
Whatever you do, don’t give up. Achieving and maintaining a healthy weight is important not only in the short term (for your performance as well as your career) but also in the long term, reducing your risk of many diseases including diabetes, heart disease, and certain types of cancer.
