Vitamins and Their Importance in Nutrition

 

The word " Vitamine " meaning a vital amine was proposed by a Polish Researcher, Dr. Cacimir Funk, in 1911 to designate a new food substance which cured beri-beri. Other terms were proposed as new factors were discovered. But the word vitamin , with the final e dropped favours the popular name.

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. It is not possible to sustain life without all the essential vitamins. In their natural state they are found in minute quantities in organic foods. We must obtain them from these foods or in dietary supplements.

Vitamins, which are of several kinds, differ from each other in physiological function, in chemical structure and in their distribution in food. They are broadly divided into two categories, namely,fat-soluble and water-soluble. 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.

Vitamins, can be of immense help in fighting disease and speeding recovery. They can be used in two ways, namely, correcting deficiencies and treating disease in place of drugs. Latest researches indicate that many vitamins taken in large doses far above the actual nutritional needs, can have a miraculous healing effect in a wide range of common complaints and illnesses. Vitamin therapy has a distinct advantage over drug therapy. While drugs are always toxic and have many undesirable side effects, vitamins , as a rule are non-toxic and safe.
