Poop: What’s Actually In It
Water makes up about 75% of your bowel movements. The remaining is an often-stinky mixture of fiber, dead and live micro organism, other cells, and mucus. Soluble fibers present in foods like beans and nuts are broken down during digestion and form a gel-like substance that turns into a part of your poop.
However, foods filled with insoluble fiber, like oat bran, corn, and carrots, are difficult for your body to digest, which explains why they might emerge in the toilet bowl trying comparatively unchanged.
