In a new Operation Supplement Safety (OPSS) PSA video, Gold Star mother Ms. Terri Bellamy-Coleman urges service members to seek out information and guidance on dietary supplements from the appropriate sources before taking them. Ms. Bellamy-Coleman’s son, who was attending the NCO (Noncommissioned Officer Academy, WLC (Warrior Leadership Course) in Fort Benning, GA at the time of his death, had been taking dietary supplements when he exerted himself during physical training, suffered a heart arrhythmia, and died. He had the sickle-cell trait, which may have aggravated the situation. She wants others to be aware of the possible risks associated with dietary supplements, especially when certain medical conditions are present, and urges service members to seek information to help prevent possible harmful health effects. Please watch the video, “A Mother’s Plea."
There are so many parts to being successful in theater that it can be tough to pinpoint what contributes to success. But research has established one part—cohesiveness—that does help Warfighter performance. In fact, cohesiveness—a group’s ability to remain united while pursuing its goals and objectives—is an important piece of the puzzle for any successful group, whether we’re talking about sports teams, squads, platoons, or other kinds.
Cohesiveness can be social (among people who like each other) or task-focused (among people who work well together) or both. In groups such as athletic teams, connecting with a task focus is far more important for performance than connecting socially. Connecting through a task focus is clearly important for Warfighters too, but the stakes are higher: Warfighters often put their lives—not the outcome of a game—in each other’s hands. And cohesiveness has other benefits, such as helping with job satisfaction and overall well-being.
In order to build and maintain team/unit cohesion, experts suggest the following:
- Use influence effectively—for collective gain, not individual gain.
- Communicate clearly—give clear expectations for roles, performance, and deadlines, and offer praise.
- Minimize conflict between unit members.
- Build trust within the unit and with leadership by showing interest and concern for one another.
- Establish a positive command climate that supports teamwork yet allows for each member’s independence.
- Have a shared sense of responsibility for the overall welfare of everyone in the unit and the team as a whole.
- Value connections within the team as well as between units and organizations.
- Focus on the strengths of the group, not just its problems and challenges.
- Build resilience at the individual and group level.
Warfighters and leaders can shape norms—both formally through policy and informally through practice—so that units/groups stick together on multiple levels.

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”).
Weight-loss (diet) prescription medications are generally not permitted, but it’s important to check your service’s policy for specific conditions that may exist. Read this OPSS FAQ to find out more details, including links to specific policies. Also, be sure to check the OPSS site often, as we add answers to other questions about ingredients in performance-enhancing and bodybuilding supplements and how to choose supplements safely.

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.
