The purpose of the Food Pyramid in dietary guidelines is to visually represent the recommended food groups and their proportions needed for a balanced diet. It encourages individuals to consume a variety of foods from each group while emphasizing fruits, vegetables, whole grains, lean proteins, and healthy fats. The pyramid illustrates the concept of moderation, suggesting larger portions of base foods and smaller portions of higher-calorie, less nutritious items. Overall, it aims to promote healthier eating habits and inform individuals on making informed food choices for better health.
