You have asked a good question. I have yet to determine if heating cold rice, pasta and potatoes reduces the amount of resistant starch. It might. I usually reheat my rice because I don;t like cold rice very much. However, cold rice is used in sushi and cold potato or pasta salad made with a tiny bit of olive oil, mustard and seasoning is wonderful
I eat my oatmeal hot
Sometimes I have two serving of fruit. The second serving is usually in the evening perhaps with a slice of homemade zucchine cake.
I am not sure about bananas. I know that I can only eat bananas that are not ripe.
