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.
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.
Mindfulness meditation is a mind-body practice that focuses on awareness and acceptance of the present moment. It’s a great tool to sharpen your concentration, deal with tough emotions such as anxiety and stress, and even give you physical benefits such as lowered blood pressure. Not sure how to do it? HPRC’s “A mindfulness meditation primer” describes what mindfulness meditation is and how to go about it, with an mp3 audio that takes you through five minutes of guided practice to get you started.
To have a healthy, long-term romantic relationship, you might find that you need to cool it with old patterns. Use these ICED tips to make sure your relationship holds up over time.
Identity: It’s easy to lose yourself in relationships. You may feel subtle (or not-so-subtle) pressure to be more like the other person and enjoy the same activities or share the same goals. But if you give in to these pressures, you can lose track of your own identity. While it’s good to adapt some over time, you also want to keep a clear sense of your own identity. Solid relationships consist of two people with solid identities.
Calm: It can feel difficult to remain calm when fear of losing your partner pops up. While its normal to experience some concern, the key to a relationship without harmful pressure is learning to calm yourself. If you look to your partner instead to make you feel better, perhaps acting a bit “clingy,” your efforts could backfire. The pressure that your partner feels can lead him or her to feel withdrawn rather than closer. If your partner’s presence feels like a “bonus” instead of a “need,” you’re on the right track.
Engage: When you see your partner upset, slow down and engage with him or her in a way that empowers both of you. Engage with empathy and boundaries. For example, “I know you feel anxious about me going out with the boys. You make me feel a bit guilty, and I think I need to deal with that guilt, but you should cope with your feelings too. It’s important for me to keep these other friendships.”
Deal: Whether you or your partner (or both) feel uncomfortable, it’s best to cope with how you feel rather than looking for quick fixes. Dealing with discomfort is key to growing individually and together. And it’s crucial to hang on to your own identity, learn how to self-calm, and engage with your partner in a way that makes sense.
Parents are one of the most important factors in their children’s fitness. You can set the example. Children of active parents are more than twice as likely to be active than those with inactive parents. You also can help your children be active by driving them—or better yet, walking or biking with them—to and from activities, being active with them at home, cheering or supervising their play/activity, and getting the right equipment for their activities. It’s important to expose kids to different activities. Once they find something they like, they’ll stick with it. Above all, make it fun!
Noticing whether your hands and feet are running hot or cold is one way to tune in to how stressed or relaxed you are. They’re also useful indicators to change—with the power of your mind—those feelings of stress.
There are many stress-reduction techniques to choose from. Here’s the simplest tool there is: Put on some relaxing music. Choose music that has repetitive rhythms, predictable patterns, a low pitch, and no vocals or percussion. This kind of music can help manage anxiety and pain, change brain activity, and increase skin temperature (similar to the hand-warming technique called autogenic training).
Combining approaches to stress reduction can also help. With this in mind (and simply because it sounds good), HPRC tweaked the autogenic training MP3 that we released earlier by adding music to the beginning and end. It’s a minor change, but we hope it will enhance your autogenic training experience.
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.
Roughly one in five teens is bullied at some point. It often involves hitting, pushing, or teasing, but gossip (both verbal and text) and being excluded are also forms of bullying.
The reasons for teen aggression are complex, but some school and home factors raise the chance of a teen being aggressive: rejection by peers, situations where aggression is socially acceptable, marital conflict and violence at home, feeling rejected by a parent, physical punishment by a parent, and/or parents who let their teens get away with any kind of behavior.
Since teens are still learning how to manage their emotions, aggressive behavior is a clue that they need more skills in this arena. Aggressive teens also are more likely to have problems at school that can follow them to adulthood, so it’s important to find solutions early. And of course, the victims of bullying suffer too.
Parents, schools, and communities can help stop aggressive behavior. Parents can reduce their teens’ exposure to aggression at home by controlling their own anger and outside the home by knowing where their teens are, who they’re with, and setting clear expectations for how to act when parents aren’t around. Teachers can learn to recognize aggression, communicate that it is unacceptable, and seek help/intervene. Schools can monitor areas where aggression is most likely to occur, such as playgrounds, restrooms, and hallways.
Stopbullying.gov (a website developed by the U.S. Department of Health and Human Services) offers lots of ideas for how to respond to bullying: Respond quickly and immediately to bullying behavior, find out what happened, and support the kids involved (both the bullies and those being bullied). In essence, don’t be a bystander. To learn more, visit this interactive page. The bottom line is that bullying is not acceptable, but it won’t stop unless you do something about it.
What are omega-7 fatty acids? And do omega-7 supplements convey the health benefits advertised?
Omega-7 fatty acids are a type of unsaturated fat. Omega-7s are considered non-essential fatty acids, which means your body can make enough omega-7s to function properly. In other words, you don’t need to get them from foods or supplements.
One of the most common forms of omega-7s, which is also used in supplements, is palmitoleic acid (not to be confused with palmitic acid, which is a saturated fat). Omega-7 supplements are marketed for health benefits such as heart and liver health, improved cholesterol levels, weight loss, glucose (blood sugar) metabolism, and immune support. Limited research has shown some benefits from palmitoleic acid supplementation, but most of the research has been done on animals and only for short test periods (less than four weeks). As a result, no recommended dose or source of palmitoleic acid exists, and there is not enough evidence to suggest that omega-7 supplements can improve heart health or health in general.
HPRC previously ran an Injury Prevention series with some general information to help keep you off profile. A new addition to the series is Injury Prevention Strategies, which will include information for the knees (specifically the anterior cruciate ligament or ACL), ankles, shoulders, and back. Check back often for the next in the series, and keep your body functioning at the top of its game!
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.
