Sugar Obesity

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 on Tuesday, Jan. 1, 2013, 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.
