I am also trying to get a handle on what is bothering me. Newly diagnosed less than a year ago, I do not have the control over this that I decided I need to have. While I wait for a consult with a dietitian, I know I need to get some nutrients into me. Bad food includes- red meat- beef & pork. Veggies except corn which does not bother me- imagine that! My diet is eggs, toast, fish- and I have lost 40 lbs. Not a fan of hanging, baggy skin, but it is what it is.
My specialists office tells me diet has little to do with it- but did encourage me to stick to soft foods while in a flare as to not irritate the inflammation. Anything with a seed is a definite no no. But fish & chips don't bother me. Potatos other than french fries bother me. It's a learning curve and outside of the pain connected with Crohns, the inability to eat good tasty food is the 2nd worse aspect of this.
