Recently someone asked a question on Paleohacks about his bad reaction to coconut oil. He mentioned scaling right between the eyes, a condition I had, though I thought it was due to something else. I knew I couldn't eat too much coconut oil with out making my stomach hurt, but I thought a little was okay. Well, I was wrong. Avoiding coconut oil since I read this question has cleared up my skin considerably.
This is the most helpful thing I've ever got out of paleohacks. Indeed, I've often worried it is mostly a facebookish site, given more to gossip, with any real answers getting lost. Apparently, there is some value in just reading the questions, though.
