Vitamin means life. The story of vitamins actually begins in 1911, when a Polish chemist by the name of Kazimir Punk extracted from rice polishings¹ a crystalline substance. This substance was capable to cure beri-beri. Analyses of these crystals revealed the presence of nitrogen in basic combination, i.e. the «amino»-nitrogen; Punk therefore called this substance «vita-mine». The root «vita» indicates that the substance is essential to life and health. In this way, the word vitamin was born. For four years before Punk's discovery a series of studies had begun in the USA to determine the value of cereals such as wheat, corn and oats as a cattle diet. Eventually it was found necessary to resort to rats to solve the problem of cereal differences.

I Today the successful isolation and synthesis of many of the substanc­es has proved that vitamins are organic chemical compounds to be present in the diet for the maintenance of^fc&^lf and health.

Vitamins are substances to be found in certain foods which are nec­essary for the growth, development and general health of the body. There are several different kinds of these protective substances to be provided in the diet.
