Tag: Function of food

According to the World Health Organization, a healthy diet helps protect against malnutrition and a wide range of noncommunicable diseases, such as diabetes, heart disease, and cancer. Food is more than just sustenance; it is any substance that provides nutritional support for an organism, essential for life, growth, and proper physiological function. Ingested by an organism, it is assimilated by the body’s cells to provide energy, maintain life, or stimulate growth.

According to the Food and Agriculture Organization, nutrients are substances that provide energy, materials for growth and repair, and aid in regulating body functions. The main function of food is to provide these essential nutrients to fuel all of the body's physiological processes, from breathing and blood circulation to growth and repair.
