Fructose is not responsible for the obesity epidemic or any other health issues the U.S. is facing. Obesity is a multi-faceted condition brought on by several factors, not just one. Allegations that fructose causes increased fat production or increased appetite are based on poorly constructed experiments which often test unrealistically high levels of fructose, much higher than the levels found in a typical human diet. These studies are also often carried out in animals that are poor models for human fructose metabolism. Consequently, the findings from these studies are extreme, and not applicable to real-life situations.
