The last few days I have spent going through all clinical studies/trials regarding acne and Omega-3 fats, iodine, antioxidants, chocolate, calorie intake, fatty/oily food, digestion, and zinc. Adding to this what I have learned regarding dairy and glycemic load, I’m sorry to say that nothing stands out for me as a smoking gun when it comes to diet and acne. We simply don’t have enough research yet, and nothing feels super compelling to me at this point. However, at least researchers are looking into how diet may affect acne, so hopefully by the next time I review the literature, the evidence available to the scientific community will start taking shape. In the meantime, based on digesting everything the research community has to offer regarding diet and acne, here is what I am personally going to do as far as diet goes:
1. Keep taking fish oil and eating wild delicious sushi I take 4 fish oil pills per day to make up for my Western-style diet, which like almost everyone living in modern society, is overly rich in Omega-6 fats from vegetable oils, grains, etc. There is enough evidence to persuade me of the overall health benefits of Omega-3s and I feel good taking fish oil regardless of whether or not it may be helping with my skin. Also, when I go out to eat, I specifically ask whether the fish or sushi on the menu is wild. Farm raised seafood is far inferior in Omega-3s and other nutrition than wild seafood.
2. Keep taking a zinc supplement. Having dived deeper into the role of zinc, I am still convinced that it is likely an important nutrient when it comes to combating inflammation and keeping bacteria in check. I’ll keep taking my 30mg per day.
3. Not worry about iodine, chocolate, fatty/oily food. I’ll keep eating seaweed salad and seafood (contain iodine). There exists no evidence showing that the amounts of iodine consumed in these foods is in any way detrimental for acne. Based on the available evidence, I’ll also continue eating a little dark chocolate every day without worrying about how my skin will react. I will also keep eating the occasional naughty greasy meal without fear.
4. Try to be generally healthy. Antioxidants are important calming agents in the body, and eating antioxidant-rich colorful fruits and vegetables is fun and tasty anyway. When it comes to glycemic load, whether or not scientists know if it will help with acne yet, I’ll try to keep my meals balanced with carbs, fat, and protein to keep my energy and mood level and avoid crashes.
A full update to the diet and acne page of acne.org is on its way with much more information on each of the above mentioned topics. In the meantime, when you look at the evidence at hand, eating healthy and in moderation will suffice as a general wrap up for what we know regarding diet and acne at this point. Not exactly a Eureka moment.
