I agree with you. I had a digestive disorder called gastroparesis for years. The diet prescribed to me by all docs and nutritionist I met with to help "manage the disease" were simple starches...potatoes, breads, rice, pasta, etc. And to think, MOST people who have gastroparesis are diabetics (although I am not). Can you imagine recommending that diet to a diabetic? It's very frustrating. Using medication to get the disease under control and then changing my diet completely eliminated the issue for me and I've been medication free (and symptom free) for almost 3 years now.
I'm glad you're feeling better. My ex-boss had Crohn's and I watch him long enough to see that his level of symptoms was directly related to his diet, exercise and stress levels.
