Myth: Acne is related to diet Reality: Prevailing wisdom in the dermatology community is that diet and acne are not related. Of course science is never a 100% reliable enterprise. But at this time, there is no evidence that chocolate, sugar, oil, milk, seafood, or any other food causes acne. Some people absolutely insist that a certain food causes acne for them, or that a specific acne diet works for them. In this case, doctors sometimes recommend that they avoid that food or follow that diet. Regarding chocolate specifically, several studies have been performed, and the answer to "does chocolate cause pimples?" is a resounding "No".
