HPRC Fitness Arena: Nutrition
Carbohydrates are essential fuel for muscles and provide a source of quick energy. But is it true that eating extra carbs before an athletic event or mission will improve your performance? Carbs becomes especially important when you put your body to test during athletic competitions and events. If your body’s available carbs run out, fatigue sets in and you can “hit the wall.” To avoid this, many athletes load up on extra carbs such as bread, pasta, and rice. Read more about the concept behind carb loading and how it can affect your performance.
Getting the right nutrients at the right time can give you the edge you need when it comes to performance. Are you drinking the right kind of beverage to keep you hydrated? Do you know what to eat after a workout to optimize your recovery? Find answers to these questions and more in HPRC’s FAQS: Fueling for Performance.
And while you’re there, be sure to check out our other Nutrition FAQs for more answers to common questions we’ve received about nutrition.
It’s the peak of summer, which means barbeques, picnics, and other food-filled events. But especially in summer’s heat, don’t forget about food safety, or it might just spoil your fun. Let the good times roll this summer with these food safety tips:
- Wash your hands. Washing your hands often is one of the best ways to prevent the spread of bacteria. Remember to use warm water and soap, and wash your hands for at least 20 seconds.
- Marinate meat safely. Marinate your food in the refrigerator, and keep it there until you’re ready to cook it. If you want to use the marinade as a sauce, set aside a portion before adding your raw meat or poultry, and don’t reuse marinade.
- Cook food thoroughly.Use a thermometer to ensure your food is cooked to the right minimum internal temperature:
- Steaks and pork—145°F
- Hamburgers and sausages—160°F
- Keep cold food cold. Don’t let your cold dishes sit out on a counter for more than 2 hours, or one hour outdoors when temperature is above 90°F. Otherwise, keep it chilled at 40°F or less in a cooler or place directly on ice.
Always remember: “When in doubt, throw it out.” A foodborne illness is not worth the risk. For more information on food safety during the summer, visit “Summer and Vacations” at Foodsafety.gov.
Children and teens are vulnerable to hunger and poor nutrition, especially during the summer months when school is out. This can lead to lower academic performance once school begins again. Poor nutrition also makes kids more prone to illness and other health issues.
The U.S. Department of Agriculture (USDA) aims to fill this nutrition gap by providing summer meals for children up to age 18. What’s more, it’s free, and children don’t have to enroll to be eligible. They just have to show up and enjoy a healthy meal. (In fact, more than one meal may be available.)
Summer meal sites are located in many communities across the country at places such as schools, community centers, libraries, parks, playgrounds, and faith-based centers. To find a summer meal site in your community, check out USDA’s Summer Meal Site Finder.
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.
