Welcome to the HPRC Blog. We've got lots of information here, from quick tips to in-depth posts about detailed human performance optimization topics.
HPRC Fitness Arena: Nutrition
Granola bars are great for a quick, convenient snack, but some are more like candy bars in disguise. They can be high in sugar, fat, and calories. There are plenty of healthy variations of granola bars, though. You just have to know what to look for. Next time you’re in a store or in the commissary, compare Nutrition Facts labels and follow these tips:
- Look for a granola bar that has at least 4 grams of protein, 3 grams of fiber, and less than 200 calories. This will help you stay full longer while keeping your nutrition in check.
- Find a granola bar with less than 10 grams of sugar. Most of it is added sugar. And watch out for hidden sources of sugar such as brown rice syrup and honey.
- When it comes to ingredients, look for ones you recognize or can pronounce. Remember, a granola bar with fewer ingredients is often better.
For information on how to read Nutrition Facts labels, check out this guide from the Food and Drug Administration.
Sports drinks that contain electrolytes and carbohydrates can be essential to performance by replenishing what is lost during activity, mostly through sweat. For activities less than 60 minutes, water is the best drink to replace lost fluids. If your exercise session or mission exceeds 60 minutes, then sports drinks can be helpful. Follow HPRC’s guidelines for maintaining important nutrients such as fluid, carbohydrates, sodium, and potassium during activity to keep well hydrated and on top of your game. Read more here.
Need a great post-workout beverage? Try drinking a glass of chocolate milk within 45 minutes after exercise to replenish glycogen stores and repair muscles.
Why chocolate milk? One 8-ounce glass of chocolate milk provides about 200 calories and the right ratio of carbohydrate to protein. It also provides electrolytes such as potassium and sodium, along with essential vitamins and minerals such as vitamin D and calcium in an easily digestible liquid form. And even better, it’s inexpensive, readily available, and 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 (but note that almond, cashew, and rice milk are not as high in protein).
How do you tell the good from the bad online? The Internet can be a great resource when you want to learn about a health condition or nutrition topic. But some websites provide nutrition-related information backed by sound research, while others base their information on myths and half-truths. HPRC offers some tips on what to avoid and what to look for instead to help you find accurate health and nutrition information on the Internet. Read more here.
Have you heard the terms “resilience” and “Total Force Fitness,” but you’re not quite sure what they mean or where they fit into the health and performance picture? Read on.
Your health is the foundation. The 2010 article "Why Total Force Fitness?" states, “nothing works without health.” Health is not just physical and not just something to worry about when you’re sick. Health is a combination of physical, mental, spiritual, and social well-being and includes practices that promote wellness in addition to those that help you recover from sickness or injury.
Resilience is next. Resilience is the ability to bounce back—or even better, forward—and thrive after experiencing hardship. It is not the ability to completely withstand hardship but rather the ability to come back from it and grow stronger through the experience.
Next is human performance optimization (HPO). Unlike resilience, which typically requires the experience of hardship, HPO involves performing at your best for whatever goal or mission you have (whether that is your PT test, a combat mission, or raising children). It goes beyond simply resisting challenges; it means functioning at a new optimal level to face new challenges.
Health, resilience, and optimal performance are the foundations of Total Force Fitness, which is defined in the “Physical Fitness” chapter of “Total Force Fitness for the 21st Century” (see link above) as a “state in which the individual, family, and organization can sustain optimal well-being and performance under all conditions.” Being totally fit requires a holistic approach—that is, an approach that doesn’t focus on just one aspect alone such as nutrition or physical fitness, but on multiple domains of fitness. It means attending to your mind (including psychological, behavioral, spiritual, and social components) and your body (including physical, nutritional, medical and environmental components). In order to achieve Total Force Fitness, these factors come together to enhance your resilience and/or performance.
This is where HPRC can help you on your quest for total fitness. By visiting each of our domains—Physical Fitness, Environments, Nutrition, Dietary Supplements, Family & Relationships, and Mind Tactics—you can get evidence-based information on a variety of holistic topics to help you achieve and sustain total fitness. But remember that total fitness is a life-long process that will ebb and flow. And it isn’t just about you; your loved ones are an important piece of the picture, too.
Man up and eat your greens! (And your reds, oranges, yellows, purples, and whites). June is Men’s Health month and a good reminder that what you eat matters. What can eating more fruits and veggies do for you?
- Reduce your risk! Eating the recommended amount of fruits and vegetables can help reduce your risk of stroke, heart disease, some cancers, and type 2 diabetes.
- Fill you up. Fiber-filled fruits and vegetables fiber can help lower your risk of obesity.
- Provide phytochemicals. Vegetables and fruits pack a powerful punch of these chemicals, which may reduce the chance you will experience chronic disease.
- Pump up your performance. Fruits and veggies contain water, electrolytes, vitamins, minerals, and carbohydrates, all essential nutrients for top performance in the gym or on the field.
What’s a great way to ensure you’re eating enough fruits and veggies? At meals, fill half your plate with fruit and/vegetables. Remember that raw, cooked, steamed, chopped, whole, sliced, and diced all count. Eat your way to health by making fruits and vegetables a colorful part of every meal. For more colorful tips, read HPRC’s articles on pink, orange, white, and purple produce.
Training for a marathon or some other endurance event? Building your endurance—by making the right nutrition choices—can make the difference between failure and success. HPRC’s performance nutrition strategies—“Going the distance”—provide the information you need to know what and when to eat for endurance.
If you limit carbohydrates and underfuel your body, your performance may suffer. Carbs feed the working muscles and help maintain blood sugar. In addition, carbs help you recover after a difficult workout or mission.
Underfueling by limiting carbohydrates can be intentional—when limiting calories, avoiding gluten, or losing weight. Or you may be limiting carbs unintentionally if you are unsure how many carbs to eat or if you’re are skipping meals or snacks due to limited time or money. And female warriors are more susceptible to under-fueling.
So what type of carbs should you be eating? Properly fuel your body by filling your plate two-thirds to three-fourths with carbs such as fruit, vegetables, whole grains, beans, and dairy. Choose a variety of fruit and vegetables to maximize vitamins, minerals, and fiber. Whole-grain breads, grains, and pastas provide more performance-boosting nutrients than white-flour and refined versions. Low-fat dairy products contribute carbs along with protein and calcium.
Carbohydrate needs differ depending your activity, type of exercise, and intensity, and your calorie needs and may change from day to day. For more information on carbohydrate needs before, during, and after activities, see HPRC’s An Athlete's Guide to Everyday Nutrient Timing.
Keep on eye on your weight and performance to help you determine if you’re taking in too few carbs. If you’re losing weight without trying or find yourself having trouble performing at your best, you may be underfueling. For more personalized recommendations on carbohydrate intake, visit a registered dietitian.
Optimal fueling includes staying well hydrated during exercise. Inadequate fluid intake can lead to dehydration that affects your mental and physical performance.
The first key is staying well hydrated throughout the day. If you start exercising with low fluid intake, you’re already behind. To stay hydrated, drink fluids such as water, 100% juice (diluted), milk or milk alternatives throughout the day. A good rule of thumb is to drink half your body weight in fluid ounces. For example, a 150-lb warrior should drink 75 fluid ounces per day. Foods with high-water content count too! Some examples of high-water-content foods are fruits (especially grapes, watermelon, peaches), vegetables (zucchini, celery, cucumbers, tomatoes), yogurt, sherbet/sorbet, and soup.
Exercise is when you can lose a lot of fluid, especially if your workouts are long, intense, or in heat or humidity. Dehydration—losing just two percent of your body weight—can lead to a decrease in performance. Drink often and drink the appropriate fluid to stay on top of your game. For more information on what to drink and when, see HPRC’s Hydration infosheet.
You may find it challenging to drink enough fluids, but some simple reminders can help. First, keep a water bottle on hand. Just seeing the water bottle is a great reminder to drink more. Also, always drink with meals and snacks. Sick of plain water? Add sliced lemon, lime, mint, cucumber, or fruit to your water. Or add to a water pitcher and keep in your refrigerator.
An eating disorder can impact your performance, both physically and mentally. But you can take steps to overcome it.
Eating disorders are serious conditions involving a person’s attitudes and behaviors toward food, weight, and body image. People with eating disorders eat extremely small or excessive amounts of food and usually feel embarrassment, disgust, and depression.
Eating disorders can be triggered by a number of causes, including genetic, biologic, behavioral, emotional, psychological, and social factors. Service members must meet certain physical requirements and often set even higher expectations for themselves. Pressure to be at an ideal weight or have the best physique can contribute to an eating disorder.
Even the most resilient service members are not immune to these triggers, and female service members are affected more than males. In addition, the number of diagnosed eating disorders in the military seems to be increasing, and many military members with eating disorders may go undiagnosed.
Not getting enough food or not eating healthy, consistent amounts of food means that your body is not being optimally fueled. And even worse, eating disorders can take a serious toll on your physical and emotional health, and your relationships.
The key to overcoming an eating disorder is seeking help as soon as you can and putting in the time. (It doesn’t go away overnight.) Research shows that psychotherapy is often the most successful approach, but treatment is complex and draws on expertise from other fields such as nutrition and medicine.
