There are various types of vegetarian diets, all of which exclude meat, while some also exclude fish, poultry, and other animal products. Although fruits and vegetables are rich in vitamins, minerals, and fiber, many of them are short on certain nutrients (such as protein). Being a vegetarian in the military can be challenging, but with proper planning—beginning with the right information from HPRC’s "Vegetarian diets - the basics"—a vegetarian diet can meet all of your nutritional needs.
Not only can plant-based diets be nutritionally complete, they also tend to be high in fiber and low in calories, saturated fat, and cholesterol. Thus, vegetarian diets offer a wealth of health benefits, including decreased risk for diabetes, heart disease, and obesity. As an added bonus, many vegetarian food options are considered “Green” foods under the Go for Green® program, which means you can eat these foods at every meal. Just be mindful of the amount of canned, fried, or dried (with added sugars) items you choose.
Facing your fears with confidence looks easy in the movies. In reality, though, we often feel confident after we face the things that scare us. Acceptance and Commitment Therapy (ACT) is a new form of “mindfulness” skills-based counseling that has been shaking up traditional therapy and self-help. With ACT, you face the hard stuff and then feel less anxious (not the other way around). ACT can help people move forward—both those with diagnoses and those dealing with more generalized anxiety. ACT teaches us that we can DARE to face our FEARs.
“FEAR” keeps us stuck:
- Fusion is about letting thoughts rule behaviors (such as “I can’t do it”).
- Extreme goals mean chasing impossible ideas (such as aiming to do a triathlon when you can’t run five miles yet and don’t have time to train).
- Avoiding discomfort is waiting till the time “feels right” before you start moving forward.
- Removed from values means you aren’t identifying what’s really important to you.
But we can “DARE” to move forward:
- Defuse. Allow yourself to take thoughts less seriously; they’re just thoughts, not facts.
- Accept discomfort. Let uncomfortable feelings exist while still doing what’s important.
- Realistic goals. Set out to do things that are within your control (such as running three miles today and four by next week).
- Embrace values. Ask yourself big-picture questions about what’s really important to you, and let your answers drive your behavior (such as “I finish what I start”).

Training on a treadmill versus running outside – is there a difference, besides the scenery? Is one better than the other? These are frequently asked questions in the running world, especially when the weather makes outdoor running a challenge. Researchers provide a short answer: Training on the treadmill and “overground” running are not the same.
If you’ve experienced treadmill running and find yourself more tired afterwards than you would on an outdoor run, you’re not alone. Studies have found that athletes actually run slower on a treadmill than their normal pace outside, although they perceive treadmill running as being more exhausting. In other words, even though it feels more difficult, treadmill running is usually less intense and less physically challenging than running outdoors.
However, running indoors can be helpful if you’re recovering from an injury since running on a treadmill is easier on your joints than running outside on concrete or even grass.
Bottom line up front, you do run differently on a treadmill than you do outside, even if you don’t realize it. If you’re training for an outdoor race, ideally you should run most of your training miles outside. When you want to or need to run indoors on a treadmill, set the incline at 1–2% to increase your exertion level to more closely replicate your outdoor runs.
If you do decide to run outside during a cold spell, take a look at our article with tips for staying safe and the many resources where you can find more ways to keep warm and hydrated even in frigid weather. Remember: Whether you stay in or venture out, any exercise is better than none!
Do you know that one in six Americans get sick from foodborne illnesses each year? Thankfully, there are safety tips and techniques that can help you prevent such incidents. Here are some quick and easy tips to remember:
Clean: Wash your hands and surfaces thoroughly and frequently with hot, soapy water.
Separate: When shopping, preparing, and storing your meals, be sure to keep raw meats, poultry, seafood, and eggs away from other foods that won’t be cooked to prevent cross-contamination.
Cook: Use a food thermometer to ensure that your meats are cooked to the right temperature (165°F for turkey).
Chill: Don’t leave leftovers (including raw and cooked items, such as pies) out on the table for more than two hours. Promptly refrigerate these items, and use or discard leftovers within three to four days.
If food looks or smells questionable, a good rule of thumb to follow is, “When in doubt, throw it out.”

With the holidays, sales, and gift-giving (and receiving) upon us, material items may be on your radar more than usual. Thinking about what to get for your significant other, parents, children, friends, and/or coworkers is on many people’s to-do lists. But where should we draw the line with materialism—that focus on the status symbols of money and possessions? And does having more really make us happier?
Ironically, some research has shown that materialism actually relates to feelings of lower well-being. Being more focused on material things can lead to greater feelings of insecurity and “neediness.” Interestingly, this doesn’t depend on personal or household income (though few studies included multimillionaires or the homeless). But it does suggest that materialism is an effect not of wealth but of one’s attitude towards material things.
This isn’t the same as the desire for money or financial success. Believing that money is important can actually improve your well-being. But your sense of well-being can suffer if you link your desire for money with status, image, success, and happiness.
So this holiday season, strike the balance that works for you and your family as to how much you should focus on material items versus other (spiritual, mental, and physical) ways to meet individual and family needs.
The Female Athlete Triad is a condition that commonly affects physically active girls and women, especially those involved in activities such as dance or gymnastics that have a heavy emphasis on weight and physical appearance. The Triad is characterized by energy deficiency, amenorrhea (menstrual disturbances), and osteoporosis (bone loss). Poor eating habits combined with high-intensity exercise can cause energy deficiency, although energy deficiency can occur even without disordered eating. Over time, estrogen decreases and causes menstrual cycles to become irregular or stop completely. However, estrogen is also important for building strong bones, so when estrogen levels drop, bones become weaker and osteoporosis can develop.
Female Warfighters can be at risk for developing the Triad if they don’t get enough calories and if training is too intense. In the short term, lack of energy will lead to fatigue and difficulty concentrating—an equation for poor performance. Continued energy deficiency, though, can lead to muscle loss and decreased strength, putting you at higher risk for injury. Then, even when you’re training hard, your performance may fail to improve or actually worsen.
You can prevent the Female Athlete Triad easily by focusing on your overall health and nutrition rather than your weight. Food is the fuel that helps you to perform at your best.
It seems that just about everyone is a runner these days, and it’s an essential part of being a Warfighter. Since 1990, the number of road race finishers in the U.S. has more than quadrupled. Participation in the largest road races has increased 77% in 14 years! More runners means more who need to learn about running injuries.

In stressful situations, people often say, “Take a deep breath!” But perhaps they should be saying, “Take a long exhale!”
When your breathing is rhythmic, and your exhales are longer than your inhales, your heart rate will tend to follow: As you inhale, your heart rate increases, and as you exhale, your heart rate slows down. This more variable heart rate is associated with fewer physical and psychological problems over the long run, and lower stress and better situational awareness during the short-run. Better situational awareness means being aware of your changing environment, while also tuning into whatever is most important right here and right now. When you hold your breath or take short, shallow breaths, your heart rate varies less—which is a sign of stress. When you’re under stress, your attention can get stuck on a perceived threat. Instead, you need to allow your attention to shift from a broad focus (such as a landscape), to a narrow focus (such as the origin of a weapon firing), and back to a broad focus (such as the whole landscape, where there may be additional threats). Paced breathing can help you do this.
Optimal breathing rates vary slightly from person to person, but about six breaths per minute (with four-second inhales and six-second exhales) tends to be in the ballpark for most people to experience some benefits.
Sex experts say that "good sex"—a key ingredient in most intimate relationships—adds only about 15–20% to an already good relationship. On the other hand, "bad sex" (such as one or both partners not being fulfilled) can take away 75% from relationship happiness. That is, when sex is going well, it helps to improve your relationship a little bit, but when it isn't, it can be destructive to your relationship and overall quality of life. Keep in mind there’s no common definition of “good” or “bad” sex. These definitions rely on each person’s perception of sex and a fulfilling sexual relationship, plus how well both partners’ perceptions match.
Not only can sex affect satisfaction in relationships, it can also improve your health! Warm affection, such as hugging and kissing, can improve happiness and well-being, as well as reduce stress. Sex is also associated with greater overall health and satisfaction. As we pointed out in a previous article, sex releases a hormone that helps you feel closer to the other person and makes you feel good.
Being sexually active, having a good-quality sex life, and a healthy interest in sex are related to improved health through middle age and beyond. In fact, research has found that regular sexual activity among older individuals is more normal than previously thought. However, it isn’t clear whether healthier people have more-active sex lives or whether active sex lives improve health. At this point, all we know is that they are positively related to each other.
