Food is any substance consumed to provide nutritional support for an organism. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals.
The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth.
The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights, recognizing the "right to an adequate standard of living, including adequate food",
as well as the "fundamental right to be free from hunger".
