I've realized that my joint pain and acne are probably due to leaky gut, exacerbated by a gluten intolerance. I stopped eating all grains a couple of weeks ago (had been 80/20 before, occasionally cheating with wheat before realizing what it was doing to me) and since then I've noticed that I seem to be sensitive to some other foods as well, including eggs and nuts (upset stomach, pain in knees and wrists, some breakouts).
I've decided to do an elimination diet to sort this out. According to what I've read, the common culprits for leaky gut are wheat, dairy, eggs, nuts and nightshades -- which I will avoid. I'm planning a diet restricted to grass-fed beef and buffalo, bone broth, sauerkraut, fish, oysters, coconut oil, and vegetables (including winter squash and yams as I seem to tolerate them). But I'm wondering if I could also eat fruit regularly, like 1 or 2 pieces a day. I can't imagine why I couldn't (I haven't read that fruit is commonly implicated in leaky gut) but I have noticed that most autoimmune diets = meat + vegetables, and do not seem to include fruit. Why is this? Should I avoid fruit to heal my gut, and if so, why? I don't need to lose weight.
