I've tried different "Crohn's diets" over the years especially the ones written by other IBD patients, but as you said, everyone is different. While some of the recipes etc in the books work, most did not. So, for me, I kept a food journal and worked from that. I know that, while I can tolerate some foods, others cannot and vice versa. Frustrating but understandable with this disease.
