Quick Carbs: Dark Side of Fructose (repost 2007)

A variety of conflicting studies and articles are coming out regarding high glycemic foods in performance. What impact do they have and what conflicting studies show is a future topic for us. Fructose is not considered an optimal source of carbs and the sports drinks and gels you use should be examined to make sure that fructose is not high on the ingredients list.

It is lower down on the listing of ingredients in Gatorade, but it is number 2, after water on Powerade (Matrix Reloaded). Powerade is said to be the official drink of the US Olympics. Perhaps it is time to revisit that choice.

At the same time this is under discussion Abel Pharmboy at Terrasig has a fine post up entitled “The Questionable Dark Side of Fructose“. He notes that the consumption of fructose has been suggested to be one of the possible causes of obesity and metabolic syndrome. In conjunction with this he links to an article at Medscape which notes the atherogenic profile of fructose vs. glucose.
