Thanks for voting for what you guys wanted me to concentrate my acne research on. The last I looked at the poll results diet and acne was winning. Now I see that scars have a few more votes. Well, scars will be next. But first, let’s delve into diet and acne. In fact, let’s get deep and dirty and nitty gritty with it shall we? Yes? Great, then we shall I’ve read every published trial and review of literature since 2008 regarding diet and acne there is good news and bad news.
Good news: Scientists are all over it! No longer is diet and acne relegated to a back seat. According to the Journal of the American Academy of Dermatology (2010), “…it is evident that dermatologists can no longer dismiss the association between diet and acne…In light of the last decade of research investigating the relationship between diet and acne, it is no longer dermatologic dogma to state that any association between diet and acne is mere myth.” In other words, researchers are conducting studies and we’re getting interesting data.
Bad news: The data is still spotty and almost all of the recent studies come with serious “design limitations” as they call them. An example of a design limitation is researchers relying on subjects’ personal recollection of their diet habits instead of actually watching what they eat. Another example of a design limitation is trusting subjects to define for themselves whether they have “acne” instead of employing a professional to count lesions across a study cohort. In other words, we can’t trust the data that’s coming out yet. We need more trials, and better trials, before we make conclusions.
Um, a little more bad news: Because pharmaceutical companies do not make money from educating the public on diet, funding for diet and acne studies is sparse. But hey, even without the pharmaceutical companies, we’re seeing a resurgence of interest in the topic of diet and acne.
My gut feeling on the subject: Regardless of whether some hunter/gatherer tribes do not have acne, it is literally impossible for us to go back to a hunter/gatherer way of living, and for real concrete answers to acne, we’ll have to include diet as only one piece of a much larger puzzle. As much as I would love for it to happen, I don’t think we’re going to find a magic bullet. I don’t think we’ll find a super bad food or food group which we’re all eating which is causing acne. I also don’t think educating people to “eat right” and “low glycemic” will clear people up to the degree any of us want.
I’ll keep updating the blog with specifics regarding some diet and acne subtopics like dairy, glycemic load, iodine, etc. for the next few updates. Hopefully with all of us wading deep into the muck of the latest research we can pool our minds and get food working for us as much as possible.
