Abstract
THE field of nutrition tends daily to enlarge. It has already established itself over considerable areas long considered to be exclusively the domain of medicine and concerned with the problem of curing and preventing disease. It has invaded chemical engineering ; for example, it now requires plant for large-scale dehydration of foods with minimum destruction of essential nutrients. In its urgent need for precise analytical data about the composition of foods and diets, it has needed to mobilize not only the analytical chemist, but also the bio-assayist— with the statistician in close attendance—the physical chemist and physicist, with a special call on those having experience in X-ray crystallography, in spectroscopy, both visual and ultra-violet, and most recently in polarography ; this is one of the latest techniques to be added to the many, such as chromatography, that have stimulated and been stimulated by our increasing knowledge about the nutrients present in what we and our domestic animals eat.
