Eat a well- balanced diet with plenty of fiber. Good sources of fiber are fruits, vegetables, legumes, and whole-grain bread and cereal (especially bran). Drink 1 1/2 to 2 quarts of water and other fluids a day (unless your doctor has you on a fluid-restricted diet). Fiber and water work together to keep you regular.
