WATER.
Our bodies consist of about two-thirds water. It helps to regulate the body processes, and supplies building material. Watery fruits and vegetables contain pure distilled water. The amount of water required for the average individual differs greatly. If water is added to our foods in the cooking process, a lesser amount is required for drinking. Wholesome, non-stimulating food will call for a normal supply of water between meals.
Pure water is as important as pure food. If you boil your water the minerals are deposited on the bottom of the kettle instead of in the system for bone-making material.
