I've had Crohn's and AS and PG for over 30 years, I've been on so many immune supressants I can't count them. Nothing worked except prednisone which I didn't want to stay on for long. When my doctor insisted last year that i begin with Humira I searched and prayed for an alternative method. I found the SCD and I havn't had a symptom since!! No pain, no diarreah, no bleeding, no anemia, nothing. It's the specific carbohydrate diet, the book is Breaking the vicious cycle, you can find it on amazon and read all the amazing testimonies. It's a diet that eliminates all poly saccarides and disaccarides. No pasta, milk, sugar, rice, potatoes, but plenty of healthy fruits, veggies, meat, fish, 24 hour yogert and honey. I only wish I had started it years ago instead of listening to my doctors who said diet didn't matter Diet is everything. Please google this diet, it's awesome. I couldn't believe the quick results I found with it. I've got my life back!!!!
