Eating with IBD can be hard.
First, you need to figure out your triggers, which you usually do through an elimination diet or by keeping a food journal where you note what you eat and how you feel after you eat it - do it for at least a week, a month is even better.
I NEVER eat fast food or at chain restaurants of any kind. Their food is loaded with preservatives, fat, and who really knows what. The typcial American diet would kill my gut if I ate it. I go more the Mediterranean diet routeI eat only whole foods that I cook myself or go to restaurants where I can request what I know I can eat. Preservatives are a killer on my gut so I stay as far away from them as possible. You can eat well, even when busy, you just have to know what you can eat and plan ahead.
Typical day for me right now without any gut problems would look like this:
breakfast: white rice, poached egg, toast with apricot jam, very weak coffee (I make it at 50% strength) cut with 50% soy milk.
snack: banana with brown spots
lunch: tuna mixed with cumin, nayonaisse (soy based), eaten with white corn tortilla chips
snack: homemade yogurt with raspberries and honey
dinner: broiled salmon, quinoa, asparagus, small mesculine salad.
I drink mostly water throughout the day. Sometimes a cup of peppermint tea or clear juice (cranberry), and maybe 2x/week a glass of red wine.
If gut issues like diarrhea, cramping, etc. exist I go the low-residue diet route or for very bad flare periods the BRAT diet (bananas, rice, applesauce, and toast.
You're going to have to experiment.
