Who developed the food guide pyramid?

The official Food Guide Pyramid was published by the U.S. Department of Agriculture in 1992. The pyramid includes food and serving recommendations, and the pyramid splits the food into five major categories.

The food pyramid evolved over time. Its was first rooted in the nutritional recommendations developed in 1894 by the USDA. Nutritionist Caroline Hunt published the first major book on food recommendations by splitting food into five categories in 1916. The USDA began publishing a basic food guide booklet in the 1980s. It covered the five general food categories that the pyramid used later, including meats, dairy, fruits, vegetables and sweets.
