Water

Water is made up of hydrogen and oxygen and has the chemical formula H20. It is a colourless, tasteless, odourless liquid, very necessary to the existence of both animal and plant life, of which it is an important constituent. For example, melons and marrows consist of 98% water, the human body about 70%, and even dried fruit and biscuits contain a very small percentage.

Within the human body, water plays an important part in the digestion and transportation of food material. The human body is continuously losing water through various metabolic processes and this is replaced by the water contained in the food and beverages which it consumes. An average of 2 pints a day is needed by the body to replace this loss. This is easily consumed by most people in the form of tea, coffee, milk, fruit and vegetables.

Water is also used in the cooking and preparation of many foods and beverages. Under normal conditions water boils at 100CC (212=F) and freezes at 0=C (32CF). Water contains small amounts of essential substances such as iodine and fluorine. although many very purified waters are deficient in these substances.
