After being so sick with Crohns disease,I followed this books diet,and after 4 months on it,I am symptom free for the first time in 10 years! And feeling fantastic,healthy,with hope for the future! Before,I didn't feel like taking a trip or doing much of anything,Now i want to do everything!I really can't say enough about how it has changed my life.Five stars just doesn't do it justice! Follow the diet very strict and see what it does for you!
