Book is excellent, best info I ever got. You put a lot of time into it. It must help many peoples out there. One info really help me from somebody else comments ( patients with Crohns are sensitive to much of Vitamin C. ) I was taking 600 to 1200 mg of Vitamin C a day as to reduce an inflamation for last 2 years ( on and off) I had a liquidy stool after that. I thought it was because of my internal fistulas. So when I stopped using high doses of Vit C my stool formation went back to normal. I am in remission now mostly of my food selection ( I found what trigger my flare ups ) Now I can continue work on my projects. So I will get back into reading some more and set up some maintenance diet latter in this year. Thank you.
