Answer:
Water and fiber
Step-by-step explanation:
A common complaint of the elderly is they don't seem to have full control of their bowel movements, and when they do, they may experience constipation.
A good way to avoid constipation is to drink plenty of water, to make sure that there is enough intake of fluids, and to eat foods containing fiber.
Fiber helps the digestive tract in that it makes sure that it is strong enough to pass the food through. The colon benefits from this because if it is not strong enough, it cannot move the waste out of the body.
