The document traces the evolution of USDA food guidance over the past several decades from general guides focused on moderation to the current MyPlate icon. MyPlate, introduced in 2011, illustrates the five main food groups (fruits, vegetables, grains, protein, dairy) through a place setting diagram and encourages Americans to improve nutrition by balancing these food groups in their daily meals. It also promotes filling half of plates with fruits and vegetables, noting their various health benefits.
