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’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.”
The Food and Drug Administration (FDA) is warning consumers to stop using dietary supplement products that claim to be antimicrobial (antibiotic, antifungal, or antiviral) drugs. These products are falsely promoted to treat upper respiratory infections, sinusitis, pneumonia, bronchitis, and colds, and they look like antimicrobial products sold in Mexico. More information, including product names, is provided in the FDA Press Release.
The Food and Drug Administration (FDA) has issued a press release to consumers warning them about a counterfeit product being represented as the dietary supplement "ExtenZe.” The counterfeit product has hidden ingredients, including tadalafil or a combination of tadalafil and sildenafil, which are active ingredients of FDA-approved drugs, making these products unapproved drugs. Taking these products with prescription medications containing nitrates could lower blood pressure to dangerous levels. More information, including the lot numbers on the counterfeit packages, is provided in the FDA Press Release.
Lazy Cakes, Kush Cakes, and Lulla Pies are the names of melatonin-laced snacks that have been in the news lately as an antidote to the trend of energy/caffeinated powered beverages and products. But there is no research available on whether they are safe, or whether they actually work.
The New York Times reported on the sale of these products and others that are being sold online and in convenience stores and smoke shops. Some claim melatonin has a relaxing effect and can be used to alleviate jet lag or simply help induce sleep. But the Food and Drug Administration hasn't approved melatonin as a food additive or confirmed its safety when used as a sleep aid.
The HPRC began encountering stories of melatonin-laced brownie products back in March 2011, and we posted a Healthy Tip then that focused on the emergence of Lazy Cakes.
