"Over all, the researchers concluded, fructose-sweetened drinks were twice as effective as the glucose-sweetened drinks in stimulating the liver to recover."

"But if the sports drink contained both glucose and fructose (in a two-to-one ratio), the riders were 8 percent faster in the time trial than those drinking glucose-sweetened fluids alone. (Most bottled sports drinks on the American market are sweetened with high-fructose corn syrup, so contain glucose and fructose in a closer to one-to-one ratio.)"
