I have a close relative with Crohn’s disease. This is another autoimmune disease that causes inflammation and damage in the bowel. Upon diagnosis, he was offered a drug to suppress his immune system and help decrease the inflammation. When he asked about diet, the gastroenterologist told him that diet modification would not help him because Crohn’s disease didn’t appear to be related to diet. I was quite surprised by this guidance because, for me, it seemed logical to suspect that Crohn’s disease could be associated with something in the diet. After all, what is the bowel most exposed to? Food!
