HPRC Fitness Arena: Nutrition, Total Force Fitness
 Here are some “sweet spots” you can watch out for on the ingredient labels of foods, drinks, and dietary supplements if you are watching your sugar intake.

Sugar can be present in foods even when we don’t know it. Some hidden sources of sugar on listed food labels are high-fructose corn syrup, brown rice syrup, brown sugar, honey, maple syrup, glucose, (or dextrose), lactose, sucrose, and the sugar alcohols sorbitol, zylitol, mannitol, and maltitol. Those people watching their sugar intake should read labels carefully to spot hidden sources.

What’s the “evidence” behind sports performance products?

Many advertisers of dietary supplements and other sports-related products make claims of enhanced performance and recovery, but a recent review found that the current evidence supporting these claims is mostly insufficient.

The dietary supplement and fitness industries are filled with sport drinks, powders, bars, pills, gels, footwear, clothing, and an array of devices all claiming to provide you with a competitive advantage, whether it be improved performance or enhanced recovery. With the ever-growing popularity of team and individual sports, professional and recreational athletes of all ages are an easy target for these claims. But how many of these claims are backed by evidence-based research?

A recent report now reviews the quality of evidence behind the claims of improved sports performance made by advertisers for a wide range of sports-related products, including sport drinks, supplements, footwear, and clothing. The team identified 431 performance-enhancing claims for 104 products advertised in more than 100 general, sport, and fitness magazines in the UK and U.S. for a single month in 2012. They found that more than half of the advertisements and their associated websites provided no evidence to support the claims of enhanced sports performance. Only 146 references were found, and only 74 of these met basic criteria for research quality and almost all of the 74 were found likely to be biased or lacking scientific objectivity. Only three studies were rated as “high” quality and probably unbiased. Such lack of evidence makes it very difficult for consumers to make well-informed decisions about using performance-enhancing sports products.

This review makes it clear that many of the claims made for sports and fitness products lack reliable evidence to support them and that more and better studies are needed to help inform consumers. In the meantime, consumers should be cautious when reading claims of enhanced performance and recovery and always remember that “true” evidence-based results mean that a substantial number of independent research studies have been performed, with findings that clearly support the claims made by advertisers. Presently, there is still no substitute for sound physical conditioning and nutrition practices.

Can’t touch this!

HPRC Fitness Arena: Environment, Total Force Fitness
Invasive species of plants may be growing in your back yard or along your ruck march. Know what to look for to prevent illness and injury.

Giant hogweed—no, it’s not an ingredient in one of Harry Potter’s potions; it’s a large poisonous plant that started to bloom in the northeast and northwest areas of the U.S. and parts of Canada earlier this month. If you’re out for a ruck march through the woods and you come across this plant, do not touch it. The sap can cause irritation and burns to your skin and perhaps blindness if it gets into your eyes. If you do happen to come in contact with it, be sure to wash your skin with soap and water and keep the area out of the sunlight for 48 hours. Giant hogweed can grow 14 feet or higher. It’s characterized by large leaves and white, umbrella-shaped flower clusters at the top of the plant. It may be difficult to distinguish from other non-poisonous plants such as cow parsnip, so err on the side of safety if you’re not sure. You can read more about identifying invasive species in your area from the U.S. Department of Agriculture.

Financial readiness—Your pre-deployment checklist

Pre-deployment checklists should include your personal finances. Financial readiness means one less thing for you and those back home to worry about.

Pre-deployment can mean a number of things to a Warfighter, from intense training or drills to saying farewell to family and friends. Preparation for deployment can be over months or at a moment’s notice with little or no time to settle your affairs. It’s important to have a checklist and contact list ready to use prior to your departure so you’re ready, whatever the scenario.

Having your personal finances in order should be a high priority. Options for being ready might include contacting a financial advisor, setting up automatic deposits and withdrawals, creating a monthly budget, checking into over-withdrawal options, adding a close friend or family member to your account to act in your absence, and reviewing your financial information and account numbers with a responsible person. Once all your financial ducks are in a row, your finances will be easy to maintain.

Your checklist should also include items such as legal documents, personal property review, auto and home insurance and maintenance, medical information, and international phone coverage.

For more information, check out DoD’s Military Deployment Guide. Finally, be knowledgeable of your rights through the Servicemember Civil Relief Act (SCRA).

Has your sunscreen expired?

HPRC Fitness Arena: Environment, Total Force Fitness
Using sunscreen is important for protecting your skin against harmful UVA and UVB rays. But for best results, make sure your sunscreen has not expired.

Your sunscreen has an expiration date—have you checked it lately? It’s meant to last up to about three years; after that, the active ingredients start to deteriorate, making it less effective and leaving you vulnerable to sunburn and sun damage. Ideally, you should be using your sunscreen often enough that a bottle doesn’t last through the summer. If that’s not the case, check the bottle you’re currently using—if it’s old, throw it out. If you buy sunscreen that has the expiration printed only on the box or wrapper, write the date somewhere on the bottle itself with a permanent marker. Practice safe sun this summer to keep you and your family healthy and happy!
