We all know sugary diets can sabotage a waistline. Now it turns out they might make brains flabby too. Sweet drinks scrambled the memories and stunted learning in lab rats in a new study—leading to "thigh concern" over what sugary diets may do to people, according to neuroscientist Fernando Gomez-Pinilla.…The next task for the team "is to determine whether the long-term effects of a poor diet are reversible," said physiologist Jill Barnes at the Mayo Clinic in Rochester, Minnesota, who did not take part in this research.
