I think pasta is good for a sore gut, unless you have the gluten issue like I do, as others have said. Then use corn pasta, it's very good. No tomato sauce for me, though, just salt and pepper.
Fresh fruit would kill me when I was flaring, except something like bananas (in moderation)
Even my healthy husband can get tummy aches and urgency from fresh fruits sometimes.
If you haven't already, then you might want to also try pineapple and berries. I'm fructose intolerant; so I mostly eat just bananas when eating fruit. I can also tolerate pineapple, which has digestive enzymes, and berries, which contains antioxidants. All three are supposed to be okay if you are fructose intolerant.

Figuring out how to reduce a flare or get into remission is a trial and error experience. Don't expect your GI to have all the answers. He was trained in making diagnoses, prescribing medications, and surgically removing the colon. He was not trained in alternative treatments. That's why they are called alternative treatments.
What works for me: Fecal transplantation, Probiotics, Anti-inflammatory foods, No HFCS, No foods high in fructose, No artificial sweeteners, No pro-inflammatory foods when flaring, Vitamins, Lexapro (for stress).
