Clean eating with Crohn and diabetes


I am not sure if I ever asked before. I want to get to a healthy lifestyle however my hubby has diabetes and Crohn. So I find it hard to keep bread and other baked goods our of the house. Veggies are something that cannot be eaten because it is so hard to buy for two diets in the house. We basically live off of chicken rice pasta and cereal in our house. I try to make eggs more but my hubby half the time has no appetite and a sad fact of our daily routine is quick to make processed meals like pf chengs. I can not for the life of me get him to a dietitian and I have tried for 5 years. Is there a chance of an IBD colitis or forums diet option? I know the simple answer it whole healthy but it is so hard. Does anyone have any suggestions? Thank you a bunch.
