Hiking Nutrition NewsHiking nutrition news: do I mean the "fluff" articles in women's magazines? You know, the "eat all the candy bars you want and STILL lose weight" headlines that grab your attention in the check out line? Nah! That's just marketing hype! I mean REAL hiking nutrition news, hot off the press. The scientific press, that is. Here's an example: ISSN Exercise & Sport Nutrition Review: Research & Recommendations. I can hear you yawning already! But wait! Here's why I LOVE journals which publish review articles. It's one stop shopping. You can get 5 years worth of information in one article, as in this golden nugget published in the 2010, 7:7 edition of Journal of the International Society of Sports Nutrition. Twenty two authors pool their knowledge and deliver it to you! Now that's hiking nutrition news a woman can love. Here's what the latest hiking nutrition news, summarized in that juicy little 43 page article, says: 1. There's been a lot of time and energy devoted to tightening up the definition of "ergogenic aid", meaning things used as training techniques to enhance performance (physical, mechanical, nutritional, pharmacological, or psychological aids, as the case may be). Hiking nutrition news should definitely include this topic! Let's bottom line this with an example: Do nutritional supplements marketed to hikers (and other atheletic people) really work? That's a question I always have when I'm standing in front of a shelf full of products screaming "I'm great! Take me home!" (Just to be clear, it's the bottles, not me, that are screaming.) The article goes into great detail explaining how to unravel this question. Nutritional supplements are regulated in the United States - sort of. The article clearly states that dietary supplements are NOT drugs, which puts them into a separate category in terms of legislation and regulation (some call it "unregulated"). This, in turn, drives marketing standards - what the manufacturer is allowed or not allowed to say in advertising the product. Have you noticed this statement on supplements? "This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease." Hmmmm....then why are you buying it? Just 'cause it tastes good? There's gotta be motivation, right? So who told you it's the thing to buy and use? Where does your information come from, and is it trustworthy? Just 'cuz Oprah or Ellen recommend it doesn't mean it will get YOU results. Especially since popular media isn't a particularly reliable source of hiking nutrition news (or any other type of nutrition news, in my humble opinion). 2. Which brings us to the next interesting topic in hiking research news: product safety and quality. Seems like many companies are going the extra mile (a little hiking pun, sorry...) to assure customers that their products are pure, safe, and have been tested, inspected, and monitored during production. An interesting recommendation in the paper: request a copy of the quality tests for a product. If the company won't provide test results, don't purchase it. 3. So how can you evaluate the claims on a dietary supplement? For example, Will it really do what the company says it will? This is a thorny question, and there are many layers to the answer. The short and sweet version goes like this: if you really want to know what the evidence for the claim is, do your homework. Search the National Library of Medicine's Pub Med Online information service. However, this can get you into deep water in a hurry if you're unfamiliar with reading jargon laden scientific papers. My advice? Stick to reputable companies: do a Better Business Bureau search, ask other hikers, look at FDA recall notices to get a feel for which companies to trust. And evaluate the claims on the products with a grain of salt: is this a reasonable claim? The rest of the lengthy article is devoted to outlining recommendations for energy intake and nutritional needs for active individuals (such as hikers). Here's an example: if you are exercising at moderate to high intensity (hiking uphill, perhaps) for an hour or more, you will of course deplete your stores of nutrients. The article recommends consuming between 10 and 15 fluid ounces of a carbohydrate/electrolyte solution every 15 - 20 minutes to keep your blood sugar (glucose levels) steady. No brand names were mentioned. An interesting table embedded in the article breaks down vitamins (an example of nutritional ergogenic aids) according to what is known about the action of the vitamin in the body, and any research evidence to link the vitamin with better athletic performance. It's a fascinating table, given the long list of ingredients on some of the "sports" type beverages and bars. So if you're into vitamins, take a look at this table. Even if you're just into eating the latest "energy" bar, this table will let you see if you're paying for hype, or evidence-based fact. One more thing I like is this sentence from the paper: "The most important nutritional ergogenic aid for athletes is water." Right on! I've been saying that for longer than I'd care to admit! Water IS a nutrient, and when I hike, I replace it regularly. Your cells (and you're a cellular trillionaire) are little bags of water. Give them what they need, and they'll give you what you need: energy on the trail. One last plug for reading this entire article (use link above): If you're curious about the safety and efficacy of muscle building/sports enhancing supplements, the authors (remember, there's a lot of them!) analyze the scientific literature and classify each of them into useful categories: apparently effective and generally safe, possibly effective, too early to tell, and apparently not effective and/or dangerous. Alas, here's where things get a little sticky: some of the authors take money from industry, meaning that there's potentially a conflict of interest in some of this information. Nevertheless, it makes for some interesting reading in your non-trail time. If you want more details on this information but don't want to wade through the entire 40+ page journal article, I'll be summarizing parts of this article in the near future in my free monthly newsletter, beginning with the recommendations on water consumption. Here's a tidbit on specific hiking nutrition news regarding sports drinks for hikers, and another on hiking calories, as a sample of what I like to share with my readers.
