by baby monster » Mar 1, 2019 That sounds like food sensitivity. Have you ever tried to narrow down what could be causing your reaction or did allergy testing? I doubt you need to eliminate all oils from your diet. My oldest has a food sensitivity to soy. Most processed food, fast food and many restaurants use soy in some shape, be it soybean oil, soy lecithin, soy flour or soy-based seasoning or flavoring. I have to manage his food very closely or he gets very similar symptoms to what you described. Swollen lips, rashes to the point he bleeds from scratching, hives and intestinal issues.
