Get both insoluble and soluble fiber
“Insoluble fiber, also known as roughage, can’t be digested by the body and therefore helps add bulk to the stools,” says Adams. “Soluble fiber draws in water and can help prevent stools that are too watery.” Great sources of insoluble fiber include vegetables, wheat bran and whole grains. For a soluble fiber you can consume nuts, legumes, seeds and oat bran.
