Food composition refers to the specific nutrients and substances found in different types of food. This includes macronutrients like carbohydrates, proteins, and fats, as well as micronutrients such as vitamins and minerals. Understanding food composition helps in assessing the nutritional value of foods and making informed dietary choices. Analyzing food composition is essential for various fields, including nutrition, food science, and health. It allows researchers and health professionals to develop dietary guidelines and recommendations. Tools like the USDA Food Composition Database provide detailed information about the nutrient content of various foods, aiding in meal planning and promoting overall health.
