Explanation:
Most foods, even those that look hard and dry, contain water. The body can get about 20 per cent of its total water requirements from solid foods alone.
The process of digesting foods also produces a small amount of water as a by-product which can be used by the body. Water sourced this way can provide around 10 per cent of the body’s water requirements.
The remaining 70 per cent or so of water required by the body must come from fluids (liquids).
Fiber is important for keeping the digestive tract working smoothly. Since we do not digest it, the fiber in food passes into the intestine and absorbs water. The undigested fiber creates "bulk" so the muscles in the intestine can push waste out of the body. Eating enough fiber helps prevent constipation.
