Does eating “forbidden food” harm the colon

The title of my post might sound weird. I mean the food that I was not allowed to eat in the past when I was first diagnosed. In the last couple of years, I started to add food that was forbidden years ago and I can’t get back to my bland tasteless food except only when I flare up. Lately, when I eat any food that has fats, I don’t get cramps. Rather, after a couple of days, I would get explosive watery diarrhea. This has been the case for the last month or more. It also coincides with my weight loss. Does eating this “forbidden food “ cause my Crohn’s to act up in the lower layers and it passes unnoticeable or is it Ok to add new “old” food since I’m on Remicade?

Ironically tomatoes are the best thing for me to eat for Crohn's especially spaghetti sauce.

I think food is an individual thing. I eat what agrees with me. I stay away from fried or greasy foods, same with spicy food. I think people are more focused on healthy eating habits which is a good thing. If I have a true flare, then I go with a low residue diet for a bit. People with IBD, whether it's crohns or UC often have to deal with IBS. Stress is a huge trigger for me causing diarrhea, it's something I try to keep under control the best I can.
