Absolutely no tomatoes, corn, peas, or raw veggies. Same for fruit - canned or well cooked and peeled. I am also diabetic
, so things like pasta, breads, rice and other "white" foods are out for me, but would probably be okay for you. I can almost always eat soups. When you make it just peel everything, cook everything well, and puree it when it's done. It seems to help fill me up and provides a good amount of nutrients.
