The Nutritional Value of Bottled Water
- 2.1k Downloads
The human body is approximately 60 % water by weight; around 75 % of lean tissue is made up of water, and less than 25 % of adipose tissue consists of water. Water performs many essential functions including the transport of nutrients and waste products around the body, acting as a medium for metabolic reactions, maintaining the structure of large molecules, and acting as coolant by way of sweat. Water is essential to survival, and 2–3 L of water a day is recommended for the average person representing a minimum of 1 mL/kcal. This amount, contrary to popular belief, comes not only from beverages but also from water found in food.
