Grab 'n' Gobble
In today's on-the-run society, where sitting down for a meal is sometimes an impossible luxury, the emergence of nutrition bars may seem to be just what the doctor ordered. Though these pocket-sized bars once found favor primarily with serious athletes looking for a competitive edge, now anyone who feels the need for a nutritional boost may keep a few stashed in a purse or a briefcase.
In the current bar-wars environment, there are literally hundreds of these prewrapped and portable products competing for shelf space at gyms, health-food stores, and supermarkets, with names ranging from PowerBar and Luna Bar to Balance Bar and MET-Rx. But nutritionists agree that not all bars are created equal. There are high-carbohydrate bars, protein bars, energy bars, breakfast bars, brain-boosting bars, meal-replacement bars, diet bars, and women-only bars. And with so much to choose from, consumers hungering for a quick nutritional fix -- whether they're recreational athletes, workaholics tied to their desks, or overcommitted moms with barely a moment to spare -- may feel dizzy from all the product overkill and heavily hyped claims.
Digesting the Bar Facts
Without a doubt, grab-and-gobble nutrition bars are great for people who race nonstop from sunup to exhaustion. "They're a convenient alternative for someone who would otherwise be reaching for a doughnut or using the vending machines for snacks at the office," says Liz Applegate, PhD, lecturer in nutrition at the University of California at Davis. "But there's nothing magical about these bars. Most of them are fine, but some are too high in fat."
Dawn Jackson, RD, spokeswoman for the American Dietetic Association, concurs, noting that the bars are convenient, especially when you're physically active. "You wouldn't put a turkey sandwich in your pocket when you go on a bike ride, but you could easily bring one of these bars with you." However, she cautions, "some of the bars have as much sugar and as much saturated fat as a candy bar. So use them in moderation."
Steve Hertzler, PhD, RD, assistant professor of medical dietetics at Ohio State University, conducted a study showing that endurance athletes may not get the sustained energy boost that they're expecting from certain bars. In his research, he compared the effects on bloodglucose levels of two popular energy bars -- the Ironman PR Bar and the PowerBar.
