Welcome to the HPRC Blog. We've got lots of information here, from quick tips to in-depth posts about detailed human performance optimization topics.
The United States Department of Agriculture (USDA) released MyPlate as the new Dietary Guidance graphic. MyPlate replaces the Food Guide Pyramid and is split into five sections for fruit, vegetables, grains, dairy and protein. The new recommendations focus on the importance of eating fruits and vegetables (half a “plate”). Go to www.ChooseMyPlate.gov for the new graphic and recommendations. For the USDA press release issued about MyPlate,
The National Center for Complementary and Alternative Medicine (NCCAM) has produced a series of fact sheets on specific herbs and botanicals. Find information on common names, uses, potential side effects, and other information by choosing any of the 45 herbs or botanical fact sheets.
The United States Department of Agriculture’s (USDA) new cooking guidelines for meats include a reduced “safe” cooking temperature for whole cuts of pork to 145ºF (down from 160ºF). They recommend using a food thermometer and allowing a three-minute rest time before serving. For whole cuts of beef, veal, and lamb, the safe temperature is the same—145ºF—but the new guidelines add a three-minute rest time after these meats, too, are removed from a heat source. For additional information, including the recommendations for cooking ground meats and poultry, read the new cooking guidelines.
Since the beginning of Operation Enduring Freedom and Operation Iraqi Freedom, approximately two million U.S. troops have deployed. The operational tempo associated with these conflicts has led to longer and more frequent deployments with fewer rest periods in between. The inevitable stress is a challenge for military and civilian communities, even as families work hard to reintegrate their families and normal routines.
In response to these ongoing demands, the Chairman of the Joint Chiefs of Staff directed the development of the Total Force Fitness (TFF) initiative, a new Department of Defense model that focuses on the health, readiness, and performance of our Warfighters. (See the Total Force Fitness section of HPRC’s website for more information on this initiative.)
Following this initiative, a team of Joint-Service and DoD experts lead by COL Bowles of the Uniformed Services University of the Health Sciences (USUHS) came together to create a model that promotes family fitness, resilience, and optimal well-being for service members and their families. This model, which is still in development, is called The Military Family Fitness Model (MFFM).
The MFFM first examines stress-inducing demands placed on military and civilian families from sudden deployment and the return home. Then, looking to build on the resilience of the family, MFFM provides guidelines, skills, and resources for the individual, family, and community to protect against the negative effects of stress. As sources of stress increase, certain behaviors indicate the need for more support (e.g., family strife, children acting out, job instability for non-service members, family role conflict, non-supportive relationships outside the family, and/or domestic violence). With MFFM, families have individual, family, and community resources for additional support. The aim of the model is to foster a multi-level approach that strengthens family resilience and, as a result, Warfighter resilience.
Individual approaches to addressing stress include breathing exercises, yoga, mindfulness exercises, and cognitive restructuring. Family strategies include developing and maintaining strong communication skills, shared family routines, and the building of support networks. The bottom line of the MFFM is that at any point along the model, individuals, families, and communities can strengthen resilience resources to promote total family resilience and fitness.
Members of the MFFM team presented the Military Family Fitness Model at the USDA/DoD Family Resilience conference at the end of April. We encourage you to get more information on the conference presentation, read the abstract, and see the PowerPoint slides presented.
WIC is the Special Supplemental Nutrition Program for Women, Infants, and Children. It provides food, nutrition counseling, and access to health services for low-income women, infants, and children. Eligibility to receive services is based on income, state residency, and “nutrition risk.” WIC is available for military families who qualify based on income. For more information, including eligibility and program services, see the Nutrition Program Facts.
Men and women in the military who operate in and around open water need protection against drowning and immersion syndrome. Quick response to cold-water immersion is important because of its immediate impact on the body. Immersion syndrome could cause cessation of breathing and/or cardiac arrest in certain people. Cold water causes a loss of heat much faster than cold air does and can quickly cause performance impairments such as not being able to fasten a life jacket or other safety equipment. Making an effort to tread water or swim only increases the body’s heat loss and hastens the onset of hypothermia.
A person alone can extend survival time by using body posture that covers areas especially vulnerable to heat loss. Those in the water should avoid movement and use the “heat-escape lessening posture” (H.E.L.P.). This posture minimizes the exposure to cold water of the individual’s groin and chest because the arms are folded across the chest and pressed to the sides and the knees are drawn up with the legs crossed at the ankles, creating a fetus-like position (see figure 13-6 in the article linked above for an illustration). Note that this technique does require the use of a personal floatation device that allows the knees to be drawn up.
If more than one person is involved, the “huddle position” should be used to reduce heat loss. In this position, individuals should press together their chests, abdomens, and groins. In addition to conserving each individual’s body heat, the huddle position helps prevent the swimmers from becoming separated before they are rescued, provides a larger rescue discovery target, improves morale, reduces shock and panic, and may reestablish a chain of command.
These survival techniques require practice and the use of personal flotation devices. Treading water in the H.E.L.P. position in heavy seas is a major challenge, and the huddle position requires that all participants be able to tread water, so being fit and prepared is essential.
We’re bombarded with ads for health products when we read magazines, turn on the TV, and go to a store. Products claim to cure an illness, improve our looks, or just help with overall health, but how do we know how to spot a health fraud? The Food and Drug Administration (FDA) defines a health fraud as: “Articles (drugs, devices, foods, or cosmetics for human or animal use) of unproven effectiveness that are promoted to improve health, well being or appearance.” Read their fact sheet for more information.
Food Safety News is reporting that Senator Dick Durbin (D-IL) has asked the FDA to clarify its regulatory position on dietary supplements and food additives on the back of widespread concerns about the marketing of melatonin-containing baked goods. A recent HPRC Performance News post notes that there have been questions raised on commercially available products such as Lazy Cakes and Lulla Pies that are marketed as "relaxation" brownies - which contain high doses of the sleep aid melatonin.
These products are being sold as dietary supplements to help people relax and fall asleep, rather than foods containing additives. Senator Durbin contends that these foods are being sold as dietary supplements but are really foods containing a dietary ingredient additive, which would require FDA approval. He has asked U.S. Food and Drug Administration (FDA) Commissioner Margaret Hamburg to see if she has the authority "to oversee the safety of foods containing dietary supplement additives."
The vast array of dietary supplement products come in the form of tablets, capsules, powders, drinks, and energy bars. You can learn about dietary supplement labels, effectiveness, quality standards, safety and risks, and other important information about these products from the National Institute of Health’s Office of Dietary Supplements publication “Dietary Supplements: What You Need to Know.”
Pistachios contain the “good fat”—unsaturated (polyunsaturated and monounsaturated)—which can help blood cholesterol levels and decrease risk of heart disease. They are also a good source of antioxidants, vitamins, minerals, and fiber. And if you’re watching your weight, pistachios can still be a healthy choice for a snack, as shown in a recent study in the Journal of the American College of Nutrition.
