There are foods that cause acne, and dairy appears to be one of them. For years, dermatologists have told acne patients that foods did not affect their pimples and blackheads. Well, a recent scientific article in the Journal of the American Academy of Dermatology has us rethinking that. Among the dietary advice I'm now giving my acne patients (both teenage and adult acne patients) is that they should limit their milk and cow dairy intake. Interestingly, it's not just the fat in the milk, nor is it the added hormones. It seems to be the milk itself. Reasons that might explain milk's role in acne include (science geek facts):
- Milk contains substances that your body converts to testosterone (a hormone that affects your pores, causing oil production and acne).
- Milk stimulates your body to produce a natural chemical called insulin-like growth factor (IGF). This IGF increases your body's own natural testosterone hormones. It also increases how well these hormones effect your pores, causing more oil production and possibly more pimples and blackheads.
