The scd diet is very restrictive, no sugar, no carbs like potatoes, corn or bread, and no processed foods. It is restrictive, but it sure beats taking hard core drugs like remicade or humira.
It takes a lot of dedication for this diet to work, and it is not an overnight fix. It takes two or three months before your start seeing results, but it is well worth it if you are not on drugs. I have been in complete remission for 7 years. Colonoscopy last year found no active disease in my gut. The only drug I do take is pentassa which has no side effects.
