Processed Diets Can Lead to Acne

An interesting discussion is now underway over at the Freakonomics’ authors’ blog about the connection beteween one’s diet and developing acne. All the chit-chat was generated by a guest blogging post from UC Berkeley psychology professor Seth Roberts.

As stated here previously, I emphatically disagree with two key components of Seth’s self-experimented diet — he drank fructose water and canola oil concoctions at intervals throughout the day — however I heartily agree with his personal discoveries regarding diet and acne. (By the way, he also did drink extra light olive oil, with which I have no qualms.)

Seth Roberts writes on the Freakonomics blog ("Seth Roberts on Acne," Guest Blog, Pt. IV):

"… based on the idea of a two- or three-day latency, I discovered that certain foods caused pimples. If my acne suddenly got worse, I tried to remember what I had eaten two or three days earlier. Diet Pepsi and pizza were the main culprits. Taking all this together, I reduced my acne about 90%. Then, as predicted, it faded away."

While you’re over at the Freakonomics blog, check out my comment there, in which I specifically single out Dr. Loren Cordain’s groundbreaking work on this subject. I hit upon Dr. Cordain’s work (thanks to a lead) while working on my upcoming book, SUGAR SHOCK! 

In fact, I invite you to look at Dr. Cordain’s most recent article, Implications for the Role of Diet in Acne. (Semin Cutan Med Surg 2005;24:84-91.) For those of you who are short on time (and don’t wish to read the full study), here’s an abstract, taken verbatim Dr. Cordain’s website:

"Within the dermatology community, a general consensus has emerged that diet is unrelated to the etiology of acne. Except for 2 poorly designed studies, now more than 30 years old, there are few objective data to support this notion. In contrast, a large body of evidence now exists showing how diet may directly or indirectly influence the following 5 proximate causes of acne: (1) increased proliferation of basal keratinocytes within the pilosebaceous duct, (2) incomplete separation of ductal corneocytes from one another via impairment of apoptosis and subsequent obstruction of the pilosebaceous duct, (3) androgen-mediated increases in sebum production, (4) colonization of the comedo by Propionibacterium acnes, and (5) inflammation both within and adjacent to the comedo. This article will provide a review of the currently available literature on the association between diet and acne vulgaris as well as a discussion of the physiologic principles that may underlie this association."

Dr. Cordain’s cutting-edge research demonstates how — despite many dermatologists’ claims to the contrary — a bad, processed diet can trigger acne.

Sure enough, the indigenous people who Dr. Cordain has studied eat veggies, fruits, lean meats and fish and almost no processed foods and have no (or almost no) acne.That’s pretty compelling evidence pointing to the benefits of a wholesome diet!

In other words, quit the processed crap, and chances are good that you, too, can have clear skin.
