Well, while it is a type of sugar that makes fruits sweet, it in fact does get processed differently in your body. Fructose, among other things, can't be stored in muscles. Your body also doesn't need to provide Insulin to process it.
When comparing something sweetened with Fructose and something sweetened with Saccharose, the sweet from Fructose has less negative health impacts.

People in the comments straight out believing all of it are sex relationships... Read the paper, or at least the headline.
