Omega-3 fatty acids make up a family of polyunsaturated fatty acids. They are important to our health, and since our bodies can’t make them, we need to obtain them from the foods we eat. Omega-3 fatty acids may reduce the risk of heart disease and play an important role in our cell membranes. So, eating more can benefit the body in many ways.
The most widely available dietary source of EPA and DHA is cold-water oily fish such as salmon, herring, mackerel, anchovies, and sardines. Other oily fish such as tuna also contains omega-3 fatty acids but in lesser amounts. Some other sources of ALA are walnuts and canola, soybean, flaxseed/linseed, and olive oils. For additional information, including health benefits of omega-3 fatty acids, read this fact sheet; and for omega-3 content in various foods, try this infosheet from HPRC.
West Nile. Dengue. Malaria. Chikungunya. No, that’s not a typo. Chikungunya (pronounced “chik-en-gun-ye”), a mosquito-borne virus that primarily occurs in Africa, Asia, and the Indian subcontinent, and Warfighters deployed to these regions have been exposed to this risk for some time, now, however, it is reportedly spreading to Europe and the Americas. Most of the cases in the U.S. involve individuals who have recently traveled abroad, but the Centers for Disease Control and Prevention (CDC) just reported the first locally acquired case, in Florida.
The viral illness is characterized by fever and severe joint pain, but other symptoms include headache, muscle pain, joint swelling, and rash. There is currently no antiviral drug for Chikungunya, and treatment is aimed at relieving symptoms. Most patients will recover fully on their own, although sometimes symptoms persist for several months.
It’s important to know your environment. If you’re being deployed to these regions or even going there on vacation, there are things you can do to protect yourself from mosquito bites and mosquito-borne infections. Wearing long pants, shirts with long sleeves, and insect repellent while outdoors reduces the chance of an insect bite. Other precautions include removing standing water from containers such as flowerpots and buckets and placing screens over open windows and doors.
If you think you could have been infected, you should see your doctor, especially if you have recently traveled to high-risk regions. Visit the Center for Disease Control (CDC) for more information about Chikungunya.
Dietary supplements with conjugated linoleic acid (CLA) are being marketed to help with weight loss. What is CLA and can it really help you lose weight? Read HPRC’s new Operation Supplement Safety (OPSS) FAQ about CLA to find out.

Post-Traumatic Stress Disorder (PTSD) can tear apart your sense of what is safe and of what is good.
Part of the diagnosis of PTSD is exposure to a traumatic event: death, serious injury, sexual violence, or the threat of any of these. PTSD symptoms such as intrusive memories, avoidance of situations or feelings, problems in thinking or mood, and feeling overly amped up are common reactions to abnormal circumstances. Think of PTSD symptoms as self-preservation instincts gone haywire. One theory holds that, because you nearly died or experienced something awful or could picture it because it happened to someone close to you, your mind/body tries to sound the alarm bells to keep you safe. But the alarm bells sound at the wrong times and in the wrong ways.
However, PTSD symptoms can come from sources other than fear of bodily harm. They also can arise from inner conflict, when emotions trigger feelings such shame and guilt or when you question fundamental beliefs (such as “the world is basically good”). Witnessing or experiencing betrayal (especially by a leader in a high-stakes situation), within-ranks violence, extreme violence, and incidents involving civilians are some of what can disrupt your world view. It isn’t just an event but the interpretation of an event that causes Warfighters to experience “moral injury.”
If you suffer moral injury as part of PTSD, you start believing you live in an immoral world, or you view yourself as immoral, irredeemable, and defective. If you’re a Warfighter experiencing these feelings, you not only feel lousy, but you are more likely to isolate yourself just when you need others more than ever. Isolation can lead to self-handicapping or self-destructive behaviors.
So how do you save yourself from experiencing moral injury as a part of PTSD? Having a healthy sense of self-esteem can be one of your best protectors. There are no quick fixes. But forgiveness—of others and of yourself—can help you to let go of moral injury. With the help of a psychotherapist, you can begin to wrap your heart and mind around what happened. And pursuing positive interactions, such as getting involved with charitable groups, can give you opportunities to relearn that you are good and the other people in the world are generally good too. Last but not least, connecting with your spirituality—in whatever way is comfortable to you—can help you navigate this difficult journey.
Activity monitors have become increasingly popular tools to help people get and stay on track with their fitness (and dietary) goals. But, researchers from Iowa State University wanted to see just how accurate some of the popular monitors really are when it comes to reporting how many calories you burn during exercise. It turns out that the majority of the devices they tested gave pretty accurate estimates (within 10-15% error). The BodyMedia FIT was the most accurate one tested, with only a 9.3% error rating, which is close to some more expensive devices used for research purposes. Other monitors such as the FitBit Zip, FitBit One, Jawbone Up, and Nike Fuel Band all fell below 15%. Since many people tend to overestimate their activity levels on their own, an accurate activity monitor is an important tool to help people keep better track of their exercise habits. Check out our comparison chart to find out more about these monitors.
E-cigarettes were introduced to help people stop smoking, but they are becoming a popular alternative to traditional cigarettes. But are they really a healthier substitute, as many companies claim? In short, we don’t yet have a full answer to this important question, and the U.S. Food and Drug Administration (FDA) is on a mission to find out.
On April 25th, FDA released a proposal for new regulations on e-cigarettes—a multibillion-dollar industry that so far has not been highly regulated. In fact, FDA currently lacks the authority to collect vital information about these products. Traditional cigarettes deliver thousands of chemicals, many of which are dangerous, to cigarette smokers and non-smokers around them. By comparison, e-cigarettes deliver substantially fewer chemicals. However, little is known about the potential dangers of the chemicals that e-cigs deliver.
Proposed new rules would allow FDA to collect information about the ingredients in e-cigarettes, as well as their health and behavioral effects. It also suggests that more research is needed to study the long-term health effects of these products.
E-cigarettes are now being marketed with flavors popular among young people. Preliminary studies have found that young people who say they would never use a tobacco product are experimenting with e-cigarettes. The proposed new rules also would require e-cigarette users to be at least 18 years of age to purchase these products.
Although it’s still unclear how the popularity of e-cigarettes will impact public health, but it’s certain that more research will shed some light on their long-term effects.
Problem solving is a great resilience skill for families. All ages can learn or fine-tune their ability to solve problems. After all, life ensures there will be plenty of problems to solve! You can specifically help children learn how to problem solve with this easy-to-remember acronym—SNAP:
S: State the problem.
N: Name the goal.
A: Find All possible solutions.
P: Pick one option.
For example, if your child wakes up tired every morning, you can help him or her identify the problem (being tired), set the goal of getting more sleep, and discuss possible solutions (such as going to bed earlier, developing a bedtime routine, or learning a relaxation skill such as deep breathing). Then help your child pick one to try for a specific time period (such as a week) to see if it works. And instead of trying to solve the problem yourself, be a coach and help your child learn how to solve problems using SNAP.
You’ve probably seen the pictures on social media and in the news: a very pregnant woman, with a heavy barbell on her shoulders, mid squat, in an Olympic powerlifting move. But is it safe for mother and baby? If this is a situation you might find yourself in, and/or you’ve talked to your doctor about a pregnancy exercise regimen, there are some things you should know about weight lifting and exercise. Read HPRC’s “Lifting weights during pregnancy” for more information.
Bad things happen. Unfortunately, you can count on experiencing different traumas, deaths, illnesses, and injuries. As a Warfighter (or military family), you can probably expect to face these kinds of situations more often than other people. That doesn’t make these experiences any more pleasant, and often it doesn’t make them any less surprising. After a major trauma, illness, or life-changing event, it is often necessary to adapt and create a “new normal.”
Studies of “post-traumatic growth” have found that trauma survivors can grow mentally, emotionally, and spiritually after horrendous experiences such as cancer, terrorism, sexual assault, plane crashes, and even combat. It’s common to react with an emotional roller coaster of denial, anger, bargaining, depression, and acceptance. Your natural instinct might be to run from these feelings. However, post-traumatic growth can be accomplished better by taking steps to approach them. The people who support you (including but not limited to therapists and family members) can do the following:
- Listen empathically, accepting and encouraging full expression of feelings.
- Avoid clichés and easy answers. Hearing “there will be brighter days” is not helpful.
- Be patient. Changing perspective won’t happen overnight.
- Offer a helpful relationship, recognizing there is no “magic technique” or “quick fix.”
You can also be an active agent in your own healing. One technique that can be useful to you is to tell and retell versions of your story in order to become more immune to the hard parts and to reach a point where you can find new meaning in it. People of any age, including Warfighters, can benefit from actively embracing a “new normal” through taking advantage of your relationships and developing a new twist on their story, even when this initially might seem far-fetched.
A key step toward achieving and maintaining a healthy weight is learning to accurately gauge how much you’re eating. In other words, how big are your portions? The most accurate way to gauge your portions is to measure or weigh your food, but who wants to take measuring cups and a scale to the chow hall? A more practical way to gauge your portion sizes is to “eyeball” them—that is, to visually compare your food portions to a familiar frame of reference. Of course, you might have larger or smaller hands, but generally speaking your hand size equates to your body size and, as a result, your portion needs. This infographic from HPRC uses your hand as your guide—a “handy” way to keep portion sizes in check, which can mean a leaner, healthier, better-performing you.
