I am on a gut healing plan now, good carbs (good carbs mean non-refined carbs)for me are just a little fruit (1 to 2 servings a day) plantains potatoes, squashes, yams, yucca or turnips. However for some they do fine on lentils, white rice (yes, not brown, because the germ part (also bran and phytates) of the brown rice has anti nutrients in it making it hard to digest).... Other beans can be OK as well, but I soak mine (when I eat them, not now I get none), and sprout, but try and at least soak them..
