This document classifies foods according to their chemical properties, functions in the body, origin, and nutritive value. Foods are classified according to their chemical nature as carbohydrates, proteins, fats, vitamins, minerals, and water. According to their functions, foods are classified as energy-giving, body-building, or protective. Foods also differ in whether they contain carbon (organic) or not (inorganic). Their origin is either from animals or plants. Based on daily needs, foods are classified as macronutrients or micronutrients. The document concludes with classifications according to nutritive value for different food groups.
