Diet & Acne
Acne is common in Western Societies affecting the majority of adolescents. Acne is almost non-existent in hunter-gatherer societies, where the diet is based on lean meats, fruits, vegetables and whole grain products.
Despite the common perception, there is no evidence that any specific food, such as chocolate, causes acne. However, there may be several dietary components and metabolic factors involved in a complex interaction.
Insulin resistance may play a role. A combination of a high glycemic load diet, which is typically found in Western societies, with a transient resistance to insulin during puberty, is thought to trigger a chain of hormonal effects that lead to acne.
By following a diet that is high in protein with a low glycemic load the incidence of acne has been shown to decrease.
