A food circle is a visual nutrition guide in the form of a pie chart used to explain healthy nutrition. An example is the United States Department of Agriculture's MyPlate, which has replaced the USDA' s food pyramid promoted until 2011 (called "Food Guide Pyramid"). Developed under the Obama administration, MyPlate shows at a glance the groups and their recommended amounts. The logo is on cereal boxes and so forth. On the U.S. government's educational website about nutrition, the different parts of the logo are clickable, bringing the reader to different pages.
