Food groups represent a method of classifying foods based on their primary nutritional composition, serving as a conceptual framework to guide the consumption of a balanced diet. This system organizes diverse food items—such as grains, protein sources, vegetables, and fruits—into categories that collectively provide essential macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals). The objective of using this categorization is to ensure that an adequate intake of varied nutrients is achieved, thereby supporting overall bodily functions and maintaining proper physiological balance. These groupings aid in dietary planning by highlighting the necessary inclusion of differing nutrient profiles required for human health.
