About Vitamins

Vitamins are potent organic compounds which are found in small concentrations in foods. They perform specific and vital functions in the body chemistry. They are like electric sparks which help to run human motors. Except for a few exceptions, they cannot be manufactured or synthesized by the organism and their absence or improper absorption results in specific deficiency disease.

Vitamins A, D, E and K are all soluble in fat and fat solvents and are therefore, known as fat-soluble. They are not easily lost by ordinary cooking methods and they can be stored in the body to some extent, mostly in the liver. They are measured in international units.

Vitamin B Complex and C are water soluble. They are dissolved easily in cooking water. A portion of these vitamins may actually be destroyed by heating. They cannot be stored in body and hence they have to be taken daily in foods. Any extra quantity taken in any one day is eliminated as waste. Their values are given in milligrams and micrograms, whichever is appropriate.

The various functions of common vitamins, their deficiency symptoms, and natural sources are discussed in brief as follows:

"Diet has the distinction of being the only major determinant of health that is completely under your control. You have the final say over what does and what does not go into your mouth and stomach. You cannot always control the other determinants of health, such as the quality of the air you breathe, the noise you are subjected to, or the emotional climate of your suroundings, but you can control what you eat. It is a shame to squander such a good opportunity to influence your health." ~Andrew Weil, MD
