The word nutrition derived from "Nutricus" meaning suckle at Brest. The acquirements of substances like growth, development and maintenance of the living body is called nutrition. Good nutrition means maintaining a nutritional status that enable us to grow well and enjoy good health. Until the nineteenth century the science of nutrition had a limited range. Protein, carbohydrate and fat had been recognised early in the 19th century. The discovery of vitamins "rediscovered" the science of nutrition. Between the two World Wars, research on protein gained momentum. By about 1950, all the presently known vitamins and essential amino acids had been discovered. In fact  nutrition was regarded as a branch of physiology and taught as such to medical students.
