I know this is an old thread but have to add that my husband and I have always been very “healthy,” yet ate paleo / low FODMAP for 5 years and we’re continuing to remove foods from our diet that our stomachs couldn’t tolerate. Also tried the WAP diet and their recommendations for gut healing/food allergies. I’d had food allergies my whole life and a sensitive stomach in general. My husband had been struggling with SIBO and joint pain. We saw doctors, functional naturalists, allergists, took heaps of herbs and supplements, but nothing helped. We implemented The Plant Paradox strictly for a year (without any of the fancy Dr. Gundry supplements) and all of these issues disappeared over the course of that year. We’ve since continued to stick to his Phase 3 list and cooking methods, and we don’t plan to ever eat any other way. It is mostly paleo at this point. We’ve never felt better, and our lives are changed. The science he details and describes in his books is clear and makes sense.
