At the same time that Frances Kelsey was acting as a human firewall, protecting the United States from the emerging European thalidomide tragedy, the United States was also struggling with the issue of how to regulate the use of chemical food additives. For the first half of the century, very few functional ingredients were added to food. After World War II, however, there was a revolution in food processing that rivaled the revolution that was occurring in the pharmaceutical and pesticide industries. The American way of life was becoming more urbanized, and there was public demand for foods that were of uniform quality, safety, and convenience. This demand, coupled with new scientific developments, led to a highly diverse supply of processed food, and led also to the use of a considerable number of food additives.
