"In Harvard research, teens who drank three-plus glasses of milk a day, especially skim milk, reported the worst acne. Outbreaks were 44% higher in skim milk drinkers than in non-milk drinkers. Possible reason: hormones in milk. Buying organic might reduce the hazard."
"Can diet cause acne? Dermatological dogma says no. New research says yes.
White bread, doughnuts, soft drinks and other high-glycemic-index foods spike insulin and blood sugar. High insulin, says Colorado State's Loren Cordain, incites the overproduction of male hormones and the formation of zits."
