I must admit that I did it so long ago I don't recall all the details.
Foods I use to eat but don't any more include garlic, onions, beans (except small amounts of humus), apples, pears, mangoes, watermelon, dried fruits, artichokes, asparagus, peas, avocado and mushrooms.
I have not been able to increase consumption of insoluble fiber foods. I have been able to eat some lean red meats about once a week with no difficulty.
