Diatomaceous earth (DE) is a powder composed of fossilized algae called “diatoms.” Diatoms are single-celled organisms found in bodies of water, and DE is used commonly for various reasons: 1) a natural insecticide; 2) an anti-caking agent; and 3) a clarifier for wine and beer. However, some people add food grade DE to their food and beverages because DE is a rich source of silicon dioxide. Silicon is a chemical element that occurs naturally as silicon dioxide in many foods, such as whole grains and vegetables.
Proponents of DE suggest that the high silicon dioxide content helps with weight loss, detoxification/cleansing, energy levels, joint pain, teeth and gums, cholesterol and blood pressure, and food absorption. Consumers and some retailers of DE supplements also claim that its abrasive (scratchy/rough) and absorptive properties improve digestive health by ridding the intestines of bacteria and parasites as well as regulating bowel movements.
There is not enough research to support these claims, and the biological role of silicon in humans is uncertain, so there is no recommended intake or DRI (Dietary Reference Intake). According to Natural Medicines Comprehensive Database, silicon is safe to consume in amounts commonly found in foods, but insufficient scientific evidence is available for its effectiveness and safety as a dietary supplement.

Man up and eat your greens! (And your reds, oranges, yellows, purples, and whites). June is Men’s Health month and a good reminder that what you eat matters. What can eating more fruits and veggies do for you?
- Reduce your risk! Eating the recommended amount of fruits and vegetables can help reduce your risk of stroke, heart disease, some cancers, and type 2 diabetes.
- Fill you up. Fiber-filled fruits and vegetables fiber can help lower your risk of obesity.
- Provide phytochemicals. Vegetables and fruits pack a powerful punch of these chemicals, which may reduce the chance you will experience chronic disease.
- Pump up your performance. Fruits and veggies contain water, electrolytes, vitamins, minerals, and carbohydrates, all essential nutrients for top performance in the gym or on the field.
What’s a great way to ensure you’re eating enough fruits and veggies? At meals, fill half your plate with fruit and/vegetables. Remember that raw, cooked, steamed, chopped, whole, sliced, and diced all count. Eat your way to health by making fruits and vegetables a colorful part of every meal. For more colorful tips, read HPRC’s articles on pink, orange, white, and purple produce.
For older men, it’s especially important to lead a healthy and physically active lifestyle since the risk for certain chronic diseases increases with age. Multiple studies have found that as little as 30 minutes a day of moderate- to vigorous-intensity exercise can significantly lower a man’s risk for heart disease and related risk factors such as diabetes, high cholesterol, and high blood pressure. Age is also a significant risk factor for developing prostate and colorectal cancers, which makes prevention and risk-factor management even more important for older men.
Exercise has been linked to lower risk and rates of death for prostate, lung, and colorectal cancers, the three most common cancers experienced by men. So get out there! Take a brisk walk, go for a jog, swim, bike, play tennis, even certain heavy outdoor yard work is acceptable for this purpose. If you need more structure, try a gym—many fitness centers offer military discounts on memberships and personal training sessions. Some military facilities also offer group and family recreational activities. The important thing is to find an exercise routine that you enjoy. If it’s not fun or motivating then it’s not likely to become part of your lifestyle.
The benefits of an active lifestyle are numerous, but prevention is one goal to keep your regular exercise program on the right track. Be sure to consult with your physician before starting an exercise routine, especially if exercise is new for you. Living a healthy lifestyle and getting screened for health complications are important ways to maintain readiness, resilience and optimal performance.
The 2015 Warrior Games will be held June 19–28 at Marine Corps Base Quantico, Virginia. From 2010–2014, the Olympic Committee hosted the Warrior Games in Colorado Springs, Colorado. This year, DoD has taken over organizing the event.
The Warrior Games use adaptive sports and athletic reconditioning to help service members recover, rehabilitate, and reintegrate following injury. This year’s games will feature almost 200 wounded, ill, and injured service members from the Air Force, Army, Marine Corps, Navy, and the British Armed Forces competing in eight different sporting events. Get more information and details about this year’s exciting and extremely competitive event!
Want to see your children equipped to persevere in the face of challenges? To instill “grit” in your kids, the trick is challenging with care, not just pushing harder.
Here are some tips to help your children develop grit:
- Praise your children for working hard and using their talents, not for already having talent. Calling them “gifted” or “talented” doesn’t help if these labels become an excuse not to work hard.
- Reward commitment by giving your children more chances to develop their interests. For example, if your child is always painting, try to encourage it by sending him or her to art camp.
- Big goals usually require a lot of sustained effort for a child—more like a marathon than a sprint. Encourage persistence with words such as “Hang in there!” or “You can do it!” But remember that children have a much shorter attention span than adults.
- Teach your children that failures and setbacks are an essential part of learning. Remind them that excellence comes from both triumphs and mistakes.
- Give your children some space to become independent, so they can be self-reliant and self-motivated and learn from their own choices.
Grit doesn’t develop overnight. It takes time. But remember that children are children and need lots of free time and play time to develop optimally. For more insight into specific parenting styles, check out HPRC’s article about how to be a warm leader, not a drill sergeant.
Pain can be unpredictable, uncontrollable, and unrelenting, so even the most resilient Warfighters can be vulnerable to it. Because of pain, you may experience symptoms of anxiety or depression; your mind may even exaggerate the intensity and awfulness of pain. Socially, you might experience criticism, rejection, and negative interactions with family, spouse, or peers. Even if interactions are generally positive, you may want to withdraw from people or difficult situations
Chronic pain, which lasts longer than three months and is unresponsive to treatment, can affect quality of life for many. At least 100 million adults in the U.S. suffer from chronic pain. Unfortunately, combat and other situations make Warfighters especially susceptible to experiencing injury and pain. One study of an infantry brigade found that three months after return from Afghanistan, 44% of the soldiers reported chronic pain.
The American Psychological Association has shared evidence that relief from pain is more likely when mind and body are both treated. The National Center for Complimentary and Alternative Medicine has also indicated that continued study of non-drug approaches to pain management is a priority.
The latest trend in treating pain is the “biopsychosocial model,” which focuses on exercise and sleep (not just meds and surgery) as important biological influences. Important psychological factors include thoughts, emotions, behaviors, and attention. And impactful social factors involve healthcare, family, and work. All of these factors can contribute to understanding and mitigating the impacts of pain.
The American Psychological Association shares concrete advice to manage pain, including these tips:
- Distract yourself.
- Stay active and exercise.
- Know your limits.
- Follow prescriptions carefully.
- Make social connections.
- Don’t lose hope.
Training for a marathon or some other endurance event? Building your endurance—by making the right nutrition choices—can make the difference between failure and success. HPRC’s performance nutrition strategies—“Going the distance”—provide the information you need to know what and when to eat for endurance.
Today is Memorial Day. Memorial Day began as “Decoration Day” after the Civil War. In 1882, Decoration Day became widely known as Memorial Day, and after WWII it became a day to remember all our fallen heroes, not just those from the Civil War. In 1967, Congress passed the law making it an official holiday to be celebrated on May 30, subsequently changed to the last Monday of May. We at HPRC extend our greatest appreciation to those who have perished for our nation and offer our sincere sympathy for the families left behind. There are many ways people choose to remember those who gave their lives as a supreme sacrifice to our country and its ideals. HPRC is dedicated to providing our Warfighters and their families the information they need to build resilience to prevent injury and illness and carry out their missions as safely and effectively as possible. Our desire is to reduce the level of sacrifice our warriors have to make as they fulfill their future missions for us and for our nation.
Individuals who practice Bikram (hot) yoga find themselves in a 104°F room for up to 90 minutes, performing various poses and breathing exercises. This intense form of yoga claims to improve flexibility, mental focus, strength, and overall fitness. Researchers have found that Bikram yogis exhibit lower stress levels, improved endurance, muscle strength, and balance after as few as 20 yoga sessions in 8 weeks. Some older adults who participated in Bikram yoga even experienced a decrease in body-fat and improved overall glucose tolerance.
Despite these potential benefits, there are also risks with doing yoga in such an extreme environment. During a Bikram yoga session, people’s core temperature and heart rate can reach dangerous levels associated with heat illness. To reduce the risks, experts suggest sessions of 60 minutes or less, slightly lower room temperatures, and frequent water breaks. Instructors should remind their students to stay hydrated and replenish the water that they’re losing through sweat. If your instructor discourages water breaks, you should find a new instructor.
If you’re new to yoga, we recommend starting off with more traditional styles of yoga that do not involve high temperatures. Traditional styles and gentle yoga (including stretching with yoga) are also beneficial and safer for adults who may be less heat tolerant and/or are beginners.
Many people find Bikram yoga to be challenging and enjoyable, but it’s important to be smart about this kind of workout.
Redotex is a drug manufactured in Mexico and being sold in the U.S. as a weight-loss product. According to the U.S. Food and Drug Administration (FDA) it is a misbranded drug and is not legal to sell as either a drug or a dietary supplement. It is not permitted for use by DoD personnel or civilians.
According to the FDA Import Alert, “it appears to be a new drug without an approved New Drug Application…” In addition, it contains a combination of thyroid, diuretic, stimulant, and tranquilizer drugs that may cause serious and potentially fatal adverse reactions. In addition to posing a health hazard, the product contains a DEA Controlled Substance that will cause a positive drug test. It is very important to read product labels, and if the label is not in English or contains any of the drug ingredients listed in the FDA Alert, steer clear, as it is an illegal product.
