A popular myth that diet has nothing to do with acne has perpetuated throughout the dermatology and the skin care community for approximately the past 40–50 years. This viewpoint seems to have stemmed from two poorly designed studies conducted in 1969 and 1971, one being the infamous “chocolate study,” which examined the effects of cacao on acne.1 There has since been much observation- and correlation-based research showing there may, in fact, very well be dietary connections to visible breakouts.
Affecting 80–90% of the U.S. population at some point in time, it may be said that acne is the most prevalent inflammatory skin disorder in existence.2 No longer exclusive to the teenage years, more and more adults are experiencing lingering breakouts, with some continuing to suffer from acne well into middle age.
