Consumers do not need to buy overpriced, sugary sports drinks in order to replenish carbohydrates and electrolytes during or after exercise, say researchers at the Appalachian State University Human Performance Lab at the North Carolina Research Campus, in Kannapolis. Instead, just grab a banana. The tasty fruit not only offers the same performance boost as sports drinks, but additional advantages, as well. Bananas provide antioxidants not found in the manmade beverages, plus a greater nutritional boost, including fiber, potassium and vitamin B6. Bananas also boast a healthier blend of natural sugars than sports drinks.
