title: Nutrition and food commodities in the 20th century.
abstract: Nutrition in the 20th century is examined with respect to changes in the American diet due to changes in the economy and evolution from an agrarian to an industrialized society. The American farm family diet from two regions of the United States during the 1930s is studied on the basis of overall availability of food commodities. A discussion of the diet staples and differences in farm family health is presented and related to nutritional deficiencies. Beginning in the 1920s through the early 1930s dietary deficiencies became a major focus of public health officials in the United States. Identification of the cause of these human nutritional deficiencies prompted significant research by government agencies such as the U.S. Department of Agriculture, Food and Drug Administration, and National Institutes of Health. Medical schools, universities, pharmaceutical corporations, and private institutions directed their resources into basic chemical research and clinical trials to assess the role of vitamins, minerals, proteins, lipids, carbohydrates, and nutrients for improving human health and nutrition. Chemists played an important role in the discovery of vitamins, minerals, and essential nutrients, validating the efficacy through tedious clinical trials. They developed synthetic vitamins affording food manufacturers and pharmaceutical companies the opportunity to capitalize upon fortifying foods for consumers. The American chemist was also responsible for the development of commodities to maximize crop yield through pesticides and fertilizers.
