MyPlate is a nutritional guide created by the USDA to help Americans make better food choices by illustrating the proper distribution of five food groups on a plate. It serves as an easier-to-understand tool compared to its predecessor, MyPyramid, and provides personalized dietary recommendations based on individual factors such as age and activity level. MyPlate emphasizes the importance of portion control, dietary variety, and limits on added sugars and saturated fats while advocating for regular physical activity.
