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.
Service members should be careful about taking dietary supplements because many of these products contain hidden active ingredients that can result in harmful effects.
The most common types of dietary supplements found to contain “undeclared” ingredients (that is, substances not listed on the label) are those marketed for weight loss, sexual enhancement, and bodybuilding. The Food and Drug Administration (FDA) has identified over 600 tainted dietary supplements. FDA specifically warns against the use of products that claim to be “alternatives” to FDA-approved drugs or “legal” alternatives to anabolic steroids.
Dietary supplements don’t require approval by FDA before being put on the market, and without laboratory testing there is no way to know the contents of a product. If you’re considering a dietary supplement, be sure to check the label to see if the product has been evaluated by an independent third-party organization.

When you forgive others, you let go of feelings that can haunt you, such as anger, hurt, bitterness, and vengefulness. Through forgiveness you also can experience positive emotions toward the wrongdoer, such as wanting the best for that person despite whatever he or she has done.
It’s natural to resist to letting go, so why should you let someone off the hook? When you don’t forgive, you suffer negative feelings too. And what you feel after the fact doesn’t change what has already happened.
Forgiveness is letting go of hurt feelings. It isn’t forgetting, overlooking, or approving of what was done. And it doesn’t necessarily mean restoring a trusting relationship. But it’s hard to let go of feelings. Here are some tips to start the forgiving process:
1) Remember the hurt. This doesn’t mean you dwell on it, but allow yourself to tune into how you really feel.
2) Put yourself in the other person’s shoes. This is a tough one. But think about the wrongdoer as a human being capable of making mistakes just like anyone else. This doesn’t excuse his or her mistake, but maybe something contributed to being misguided.
3) Consider your own past mistakes. Picture times when you made mistakes. You don’t need to compare your mistakes, but remember how it felt and how you benefitted or could have benefitted from forgiveness.
4) Once you forgive, commit to it. You may feel tempted to give in to the negative emotions again, letting them rule your thinking and behavior. Instead, revisit all the ways in which forgiveness makes sense, and let your emotions catch up later.
Forgiveness probably won’t happen overnight, but if you commit to the process, you may find relief from your own pain.
One key ingredient of trust is dependability—being able to depend on those around you. And trust is essential in all your close relationships, whether with your commanding officer, your spouse, or your coworker. You can strengthen your own dependability through the following:
- Be there for others consistently. This can be as simple as returning calls or emails in a timely manner. Or it can be, for example, having your buddy’s back in a training exercise, “saving” his life.
- Always act out of concern for another. For example, if a coworker is being badmouthed would you speak up to clear his or her name?
- Share common interests or missions. If someone feels that you have similar goals and values, he or she is more likely to rely on you. For example, are you more likely to accept your supervisor’s influence if you know he or she values the same mission you do? The same goes at home: If your spouse feels that you both put the needs of your family over your individual interests, he or she is more likely to listen to you and trust you.
When you build trust by being dependable, you may find that those around you become more trustworthy and dependable too.”
An “adverse event” can occur as a result of taking some dietary supplements. Learn how to identify an adverse event from the Operation Supplement Safety (OPSS) FAQ, and find out where you can go to report one. And for healthcare providers, HPRC has a helpful video, “How to probe for dietary supplement use and report adverse events.” (Click on the “Video” tab to access the link.) Documenting adverse events is an essential part of how the Food and Drug Administration (FDA) evaluates potentially dangerous dietary supplements, so it’s very important to report potential problems.
Service members and their families relocate a lot, and moving to a new home is hard enough without adding injury. Here are some tips on how to properly handle heavy objects such as moving boxes and furniture, and how to take care of yourself if you do sustain an injury:
- Wear less-restrictive clothing such as looser-fitting pants or workout clothes.
- Wear closed-toe shoes.
- Take breaks when necessary. Stretching and reassessing your mechanics can help you maintain proper posture when lifting. HPRC has tips on how to maintain flexibility and remove tension in your body.
- The U.S. Army has fact sheets on Lifting Techniques for handling heavy objects and How to Safely Perform Pushing and Pulling Tasks.
- Remember to keep your core tight, and use your leg muscles rather than your back to lift heavy objects.
The best way to prevent back injury is to strengthen your back and core muscles. The National Institutes of Health (NIH) has suggestions and exercises to help build your back.
If you’re sore from all the lifting or think you may have pulled something, you can treat the pain with ice and rest—and perhaps an over-the-counter pain reliever—for the first 48 hours. Follow NIH guidelines on how to further treat your back pain if it’s acute. However, if the pain persists, consult your doctor to rule out a more serious back problem or injury before you do any more heavy lifting. If all seems well, consider core-strengthening exercises to support your back. Another option is a yoga class to relieve your pain, build your muscles, and return your back to normal function.

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.
Not only can meditation help with stress, it may even boost your immune system and reduce inflammation. In fact, research has found that people who have been in a structured mindfulness program actually had fewer sick days compared to those who didn’t meditate. Even when you’re sick, meditation may actually help you feel better (and happier) in spite of lingering symptoms. And although meditation doesn’t seem to help the elderly to the same extent, it can still help some.
Not sure how to get started or how to advance your practice? Check out HPRC’s “A mindfulness meditation primer” and the MP3 audio files linked there.
Hypoxia, or insufficient oxygen supply to the body, is a stress factor associated with high altitude in aviation. It’s caused by low oxygen levels and decreases in partial pressure. Flight above 10,000 feet is dangerous and restricted without supplemental oxygen, and even the best oxygen and pressurization systems fail sometimes. Above 10,000 feet, an aviator’s “Time of Useful Consciousness” (TUC) begins; this means that you’re going to start having problems focusing, reacting, and making decisions. At 15,000 feet your TUC is around 30 minutes, at which point you’re more likely to be unconscious than not. At 22,000 feet it’s only 5–10 minutes, and by 28,000 feet it can be as fast as 3 minutes! Look out for these signs (what you can see in somebody else) and symptoms (what you can notice in your own body):
- Cyanosis (bluing of the fingertips or lips)
- Decreased reaction time
- Impaired judgment
- Unexplained happiness/euphoria
- Visual impairment
- Lightheaded or dizzy sensation
- Tingling in fingers and toes
If you notice any of these signs or symptoms, remember to find the emergency oxygen, use it, and land safely!
To be good at something, you can’t avoid hard work. It often requires 10,000 hours of “deliberate practice” to become an expert in a profession, sport, game, or other skill. You can’t just go through the motions of practice sessions. You need to engage in “deliberate practice” in which you’re highly focused on mastering specific skills in complex conditions.
The most impressive performances require talent, but even the most talented people have to deliberately train skills to reach the highest level of capability and performance and then to maintain that level.
To develop and maintain your own talent, try the following:
- Train your body, mind, and emotions with specific skills that are most related to what you want to achieve.
- Have a sense that “I can do this.”
- Cultivate the ability to cope with the emotions of disappointments and setbacks along the way.
- Listen to feedback from others (a commanding officer, coach, or mentor) and put it into practice.
The video below (source) shows one example of where deliberate practice matters. Doctors who deal with a “Code Blue” heart failure situation hope for the best, but they consistently (and deliberately) prepare for the worst.
