VITAMINS – INTRODUCTION
Vitamins and their place in human nutrition are very poorly understood by most people.
Sold and swallowed in large quantities to give instant energy, restore potency or prevent colds, they represent an expensive, but also a probably useless fad.
The vitamins are organic chemicals present in small quantities in food, and are necessary for the normal nutrition of the body.
The body requires a certain minimal amount of these chemicals daily for the proper maintenance of health. If the diet contains less than the required amount for long enough, then signs and symptoms of a deficiency state will occur.
However, taking an excess quantity of vitamins — above that necessary for health — provides no extra benefit. In fact, with some of the vitamins, such as A and D, definite disease states may occur from excessive intake.
