This document discusses portion size and its impact on health. It notes that today's portion sizes, especially at restaurants and in packaged foods, are much larger than in the past. Eating large portions can lead to overconsumption of calories and weight gain over time. The document recommends using the Mediterranean diet plate as a guide for appropriate portion sizes to support health and weight management. It emphasizes filling half the plate with vegetables, one-quarter with starch or grain, and one-quarter with protein.
