Detail

Food is any substance[1] consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as fatsproteinsvitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to produce energy, maintain life, or stimulate growth.

Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy required by the ever increasing population of the world is supplied by the food industry.

Food safety and food security are monitored by agencies like the International Association for Food ProtectionWorld Resources InstituteWorld Food ProgrammeFood and Agriculture Organization, and International Food Information Council. They address issues such as sustainabilitybiological diversityclimate changenutritional economics,population growthwater supply, and access to food.
