Abstract

By SAMUEL LEPKOVSKY Division of Poultry Husbandry, University of California, Berkeley, California AND HARRY J. BORSON Department of Medicine, University of California School of Medicine, San Francisco, California We have entered a new era of nutrition which has altered our approach to experimental and clinical problems. We owe much to the biochemist, microbiologist, endocrinologist, and geneticist for laying the groundwork. The essential events of nutrition go on in the living cell, which must be pre­ sented with a balanced diet that may or may not resemble the diet presented to the total animal. The essential nutrients act in large part as components of cellular enzyme systems. Superimposed upon these enzyme systems are hormones which seem to exert regulating effects on enzyme reactions. Transfer of food from environment to cell is a major problem in nutrition. There are at least three aspects to this problem: (a) The transfer of food from the environment to the gastrointestinal tract.
