Who created the food guide pyramid?
Healthline says that the first nutrition guide was developed in 1916 and was based on five basic food groups. Revisions expanded the number of food groups to 12 during the Depression. The guide was revised again in the 1940s, reducing the number of food groups to seven and then to four. Further revisions in the 1950s resulted with a guide that remained in place until the end of the 1970s, when a new food pyramid came into being. This remained in use for about 30 years, until a new nutrition guide called “My Plate” was developed in 2011.
