Frequent intake of sweets may lead to tolerance similar to addiction

From ABC News (2/24):

Researchers at the Oregon Research Institute in Eugene found that adolescents who consumed more ice cream over the preceding two weeks enjoyed milkshakes less, according to brain scans. "We believe that means the more an individual is consuming a high-fat, high-sugar and high-energy food, they develop a tolerance of it in a similar fashion that you see happening with drug addiction or alcohol addition," researcher Kyle Burger said.
