I'm currently reading Carol Sinclair's book and now really confused. In her book she stated that those that are helped by the diet are usually HLA +. So, am I wasting my time if I was negative? I feel like she is saying in order to even have AS you need a positive blood test. Also, diet wise I'm feeling really frustrated. After reading her book it seems like cauliflower, broccoli,'carrots and a few others are not recommended. Even kale was suspect. I seriously feel like the list is getting smaller and smaller...
