TAKE-HOME MESSAGE
- The authors present a review of the recent analyses of a possible relationship of dietary factors and acne. They conclude that it is likely there is a causal association with acne induced by the intake of high glycemic–index foods.
- While previously thought to have little effect on acne, recent evidence indicates that diet does play a role, particularly high glycemic–index foods, and counseling our patients about dietary changes as an adjunct to other therapies should be considered.

The controversial topic of diet and acne again comes to the forefront in the recent article published in the Journal of Drugs in Dermatology by Drs. Mahmood and Bowe. This article provides an elegant review and discussion of the recently published studies on diet and its effects on acne. Despite design flaws within the individual studies reviewed, the summary of all the data lends support to the role of high-glycemic foods in the development of acne. This article reaffirms that the role of diet in the development of acne is no longer a myth. Dermatologists are encouraged to discuss the avoidance of refined carbohydrates and high glycemic–index foods with their acne patients.
ABSTRACT
The prevalence of adult acne in the US appears to be increasing over the last few decades. But what’s behind the rise: is it nature or nurture? We are well aware that genetics can strongly influence a patient’s risk of developing acne. However, significant changes in germline genetic variants are unlikely to have occurred over the last 20 years. Consequently, we are forced to examine environmental variables, including diet. This review article presents the most updated evidence supporting a link between refined carbohydrates and acne. Based on the data summarized here, dermatologists should encourage their acne patients to minimize their intake of high glycemic index foods.
