Fructose may spur overeating, study says

High fructose corn syrup is listed as an ingredient on a can of soda. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating. The study, in the Journal of the American Medical Association today, is a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role.
