Box, I don't eat many fruits because of the sugars. Sugar definitely causes acne for me. Not sure if it's a hormonal spike, insulin resistance, candida response, or something else. I just know that I'm clearer w/o sugars.
Sustakp, I try to avoid nightshades because I've heard bad things, and they contain something called solanine, which is apparently not good for you. I also know that they're a big allergen, but I've never been tested for food allergies.
