I don't think I have too much of a problem with tomatoes, but I have heard about people needing to deseed and peel them before eating. If you can manage them in a tomato sauce, that may be why - the things that are hardest to break down (seeds / skin) just aren't there, or have been blitzed beyond recognition. I do find, though, that they give me a lot of bloating. This morning, I received a list from my consultant of low, moderate and high flatulogenic foods (i.e. gas production levels). Tomatoes are on the low list. This morning, I also ate raw tomato in an omelette and I feel like my stomach lining is on fire, and my bloating has increased. Clearly, different effects happen for different people. If you can't bear the thought of eliminating tomatoes from your diet, you could always try a little amount on a day where you're at home, with nothing to worry about getting done, etc.
