Dietary interventions for acne

Acne is a Western disease.  You ever see someone living in a non-Westernized country with acne?  Although the association between diet and acne has seemed at best controversial in scientific circles, since 2007 there have been consistent observations that several dietary factors do in fact affect the incidence of acne.

THE QUICK TAKE:  Western diets have high calorie uptake, high glycemic load, high fat and meat intake, as well as increased consumption of insulin- and IGF-1-level elevating dairy proteins, all of which lead to hormonal changes that can cause acne.    In a large study done in South Korea, intake of instant noodles, junk food, carbonated drinks, snacks, processed cheeses, pork, chicken, nuts and seaweed were significantly higher in acne patients than in the controls. Conversely, the frequency of vegetables and fish intake was significantly higher in the control group than in the acne group. The best diets to cure acne?  Any with lots of fruits and vegetables, and no dairy products:  A vegan or paleolithic diet.
