According to the USDA's ChooseMyPlate.gov website, eggs are part of the protein group, not the dairy group. Other protein foods include meat, poultry, seafood, beans and peas, soy products, nuts and seeds. Peas and beans are considered members of the vegetable group, as well.
The dairy group consists of milk, calcium-fortified soy milk and products made from milk that are good sources of calcium. Yogurt, cheese, pudding, frozen yogurt and ice cream are part of the dairy group, but butter, cream cheese and cream are not.
Eggs are sometimes mistakenly considered part of the dairy group become of their placement in supermarkets, according to The Huffington Post. Eggs are located in the same section as milk, cheese and other true dairy foods.
