Growing up I have never had clear skin and as a rule have tried to keep track of any different foods that seem to aggrivate it. As I have gotten older my skin has cleared up quite a bit but I still noticed that my forhead would break out when I had ice cream. So I cut that out and tried experimenting with different dairy products. Ice cream, milk, and yogurt all cause some sort of breakout. Cheese does not seem to bother me. I firmly believe that milk does have an affect on skin. Just think of all the hormones pumped into it! For anyone who is interested:
other breakout culprits: Caffeine, creatine, fat burners, hydroxycut, ripped fuel etc...
