A food pyramid is a visual guide that illustrates the different food groups and their recommended proportions in a healthy diet. It typically consists of several levels, with the base representing foods that should be consumed in larger quantities, such as grains, while the top includes foods that should be eaten sparingly, like sweets and fats. The food pyramid helps individuals understand how to balance their meals by emphasizing the importance of variety and moderation. Each section of the pyramid represents a different food group, including fruits, vegetables, proteins, and dairy, promoting overall health and well-being.
