Question: do oats make you poop?
Answer: Oatmeal. Oatmeal offers up the best of both fiber worlds: a half-cup of dry oats contains 2 grams of insoluble and 2 grams of soluble fiber. Insoluble fiber adds bulk to stool and helps food pass more quickly through the stomach and intestines, while soluble fiber dissolves in water and forms a gel-like material.
