Suicide is a complex issue with many contributing factors, including mental health issues. Focusing on treating mental health issues and strengthening mental fitness is key for suicide prevention. Currently, efforts within the military focus on education, early intervention, decreasing stigma towards mental health treatments, and adapting a holistic approach to fostering mental fitness—which includes exercise. Learn more about how physical activity and regular exercise can improve mental health in HPRC’s answer to “Can exercise be a part of suicide prevention?”
If you’re avoiding grains due to a particular diet plan, or if you think you have to exclude grains due to gluten sensitivities, you may want to think again. HPRC has put together a table of grains (with and without gluten) and their basic nutrients to point out how nutritious grains can be. Even for those who are gluten-free or sensitive to gluten, the table shows there are plenty of healthy, gluten-free options to incorporate into your diet.
As the table indicates, whole grains are very nutrient dense: They contain fiber, vitamins such as niacin and folate (and other B vitamins), minerals such as calcium, iron, magnesium, potassium, manganese, zinc, and selenium, as well as protein and branched-chain amino acids.
A diet rich in whole grains has been associated with lower risk of Type 2 diabetes and cardiovascular disease. Paleo diet followers, as well as those who are following a gluten-free diet, need not eliminate whole grains from their diet. The benefits are vast, with many choices for a varied diet. For more information about whole grains, see the ChooseMyPlate.gov resource, “Why is it important to eat grains, especially whole grains?”
Did you know that the nature of your family relationships can impact your children’s sleep? Children in home environments with verbal and/or physical conflict do not sleep as well as children in more nurturing home environments. Children exposed to negative family interactions are likely to wake up more, stay awake longer in the middle of the night, and/or sleep less overall.
The conflict can be between parents and children as well as children observing the interactions between their parents. The kinds of behavior include yelling, name-calling, making threats, and physical assault such as slapping or hitting with a closed fist. Behavior like this is often triggered by anger and/or stress, but you can learn to control your anger and reduce family stress, which will help your child’s sleep and a whole lot more. Thus, growing up around nurturing relationships can have multiple benefits.
Antigravity treadmills are becoming increasingly popular in injury prevention and rehabilitation settings. These special treadmills reduce the stress placed on the lower body during rehabilitative exercises, like running and walking, while still conditioning muscles. However, there are still questions as to whether the scientific evidence supports their considerable cost. For more about the use, evidence, and cost of these devices, read HPRC’s “Effectiveness of Antigravity Treadmills for Injury Rehabilitation.”
Stress isn’t an isolated event. It can infiltrate your life in many ways. A survey of more than 12,000 military personnel across the services revealed the impact of stress levels on Warfighter performance. Compared with those with low stress, Warfighters with high stress were much more likely to be late for work, leave work early, get hurt on the job, or miss work altogether because of illness or injury. These trends were especially strong among a smaller subset of personnel who had recently needed a mental health evaluation. Other research suggests that stress can combine with a person’s (often unknown) predispositions, sometimes triggering mental health issues.
Depending on the severity of mental health concerns, focus on performance can take a back seat. So stress, mental health, and performance often go hand in hand. Stress-management techniques and proactive approaches to mental health can help stressed Warfighters perform their best.
Iodine is an essential nutrient. It plays a key role in how well your thyroid functions and is particularly important during pregnancy and breastfeeding for the development of your baby’s brain. The Recommended Dietary Allowance for iodine for most adults is 150 micrograms (mcg). But women who are pregnant or breastfeeding need slightly more: 220 mcg and 290 mcg daily, respectively.
Iodine is present in some foods such as fish, dairy products, fruits, vegetables, and grains. Iodine is also added to table salt—referred to as “iodized salt.” Although most Americans eat too much salt, much of it comes from processed foods and typically isn’t iodized. Consequently, many women who are pregnant are iodine-deficient. If you’re pregnant or breastfeeding, the American College of Obstetrics and Gynecology and the American Academy of Pediatrics recommend taking a prenatal vitamin to ensure you’re getting enough of all your vitamins and minerals, including iodine. In addition, if you’re vegan or you don’t eat dairy products or fish, talk to your doctor about your iodine status.
Read all prenatal dietary supplement labels carefully—whether they’re prescription or over-the-counter—so you can be certain your prenatal vitamin contains sufficient iodine to meet your needs during pregnancy and breastfeeding. Also, be sure to look for one that is third-party certified. For more information about iodine, read this fact sheet from the National Institutes of Health’s Office of Dietary Supplements.
Whether training for a mission, an athletic event, or simply to maintain your edge, there are strategies you use to enhance your chance of success, including “rules” such as figuring out where you are before you start and setting up an environment that supports your new plan. Check out HPRC’s new card, “Peak Performance: Rules of Engagement,” to learn all of them. And for even more information, check out the accompanying Performance Strategies.
The Military Health System has declared that June is Men’s Health Awareness Month. Understanding your personal health risk factors and getting screened for potential issues is the best way to stay healthy at any age. Prostate, lung, and colorectal cancers are the three most common cancers among men. The good news is that exercise and physical activity have been liked to lower risk and lower rates of death for these types of cancers. So stay active and visit a doctor for regular health screenings, and pass on to the boys in your life about the importance of regular exercise and physical activity. Living a healthy lifestyle and getting screened for health issues are important ways to maintain readiness, resilience, and optimal performance.
Even ten years ago, one survey found that nearly 70% of patients admitted to emergency and intensive care medical facilities did not inform the medical personnel of their dietary supplement use. However, some dietary supplement ingredients can retard the effects of prescription medications, others can intensify their effects, and yet others can be the reason a patient arrived at the emergency or intensive care facility in the first place. For example, more than 90 dietary supplement ingredients are known to affect blood clotting, which could mean that a wounded Warfighter could bleed more heavily than an emergency medic might otherwise expect.
According to an April 2014 article in Critical Care Medicine, recent adverse events associated with dietary supplements highlight the importance of letting medical personnel know if you are taking any supplements. As we pointed out in a recent article, you become the essential participant in making sure that your use of dietary supplements does not lead to serious consequences. Be sure you tell medical personnel about your dietary supplement use before you receive treatment. It could save your life!
We’ve said it before: The Nutrition Facts label on a food package can be a Warfighter’s best friend. But it might be getting a facelift, so to speak, to reflect the latest scientific information, courtesy of the Food and Drug Administration (FDA). The overall “look” of the label will be almost the same, but certain parts will change or be enhanced. Here are some of the proposed changes:
- Serving size: Updated to reflect the way people eat and drink today
- Calories and Servings: Shown in larger type
- Daily Values (DVs): Updated for various nutrients, such as sodium, dietary fiber, and vitamin D
- % DVs: Listed first because it’s easier to read left-to-right
- Added sugars will be shown on a new line.
- DVs for vitamin D and potassium will be included.
- Calories from fat: Going away because according on research, the type of fat is more important than amount. However “Saturated Fat” and “Trans Fat” will remain on the label.
Take a look at the old and new versions side-by-side and then visit HPRC’s Facebook page to tell us what you think of the proposed changes! FDA is seeking comments on the proposed changes, and the closing date has been extended until August 1, 2014, so this is your opportunity to be heard.
