Acne in adolescence: A role for nutrition?

Acne prevalence varies substantially between populations and is low in non-Westernised societies consuming traditional diets. A unifying feature of traditional diets is low glycaemic load. High-glycaemic-load diets have recently been implicated in acne aetiology due to their ability to affect insulin demand, androgen bioavailability and insulin-like growth factor-I activity. The beneficial results of a low-glycaemic-load diet on acne observed in a recent trial require confirmation in larger studies.
