The document outlines the "half-plate rule" for optimal nutrition. It recommends filling half of the plate with fruits and vegetables, one quarter with protein, and one quarter with grains at each meal. It provides examples of portion sizes for each food group to follow the rule. It also includes a sample one-week meal plan applying the half-plate rule for breakfast, lunch, and dinner ideas. The goal is to make healthy eating simple through this visual guide of balancing food groups on the plate at meals.
