Answer

Diet therapy has been suggested. Fulton et al performed a study on chocolate, having teenage patients with acne consume 1 bar of chocolate each day. Some of the patients improved and some worsened, but the vast majority were unchanged. [72] This study helped decrease the emphasis on diet as a causal factor in acne vulgaris. However, investigators always returned to the diet question. Data suggest that the westernization of certain Native American populations and the related consumption of unhealthy "junk" foods (eg, potato chips, soft drinks) has had a negative impact on general and skin health, resulting in acne flares. Skim milk, compared with full-fat milk, has been found to have a positive association with acne, especially in teenagers and young adults. [73, 74] Causation was not able to be drawn from the case control studies, but the mechanism involving hormonal constituents of the skim milk has been postulated. [73] . Whey protein is a commonly used supplement that has been suggested to worsen acne and should be discontinued if flaring of the condition is associated with its use.
