A concise historical narrative of NAICS Code 621399-25 covering global milestones and recent developments within the United States.

• The Nutritionists industry has a long history dating back to ancient times when Hippocrates, the father of modern medicine, said, "Let food be thy medicine and medicine be thy food." In the 18th century, Antoine Lavoisier discovered the role of metabolism in the human body, which led to the development of modern nutrition science. In the 20th century, the discovery of vitamins and minerals and their role in human health led to the emergence of the modern nutritionist profession. In the United States, the nutritionist industry has seen significant growth since the 1970s, with the establishment of the American Dietetic Association, now known as the Academy of Nutrition and Dietetics, and the passage of the National Nutrition Monitoring and Related Research Act in 1990, which established the Dietary Guidelines for Americans.
