Editor's Note: This is an area where Wikipedia falls short and suggests the food industry as the primary source of food instead of food sovereignty.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as 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.
Historically, people secured food through two methods: hunting and gathering and agriculture. Today, the majority of the food energyrequired by the ever increasing population of the world is supplied by the food industry.
