'''Food''' is any substance<ref>{{Cite news|url=https://www.britannica.com/topic/food|title=food|work=Encyclopedia Britannica|access-date=2017-05-25|language=en|deadurl=no|archiveurl=https://web.archive.org/web/20170727134023/https://www.britannica.com/topic/food|archivedate=2017-07-27|df=}}</ref> consumed to provide nutritional support for an organism. It is usually of [[plant]] or [[animal]] origin, and contains essential [[nutrient]]s, such as [[carbohydrate]]s, [[fat]]s, [[protein (nutrient)|proteins]], [[vitamin]]s, or [[Mineral (nutrient)|minerals]]. The substance is [[Ingestion|ingested]] by an [[organism]] and assimilated by the organism's [[Cell (biology)|cells]] to provide [[energy]], maintain life, or stimulate growth. Historically, [[human]]s secured food through two methods: [[Hunter-gatherer|hunting and gathering]] and [[agriculture]]. Today, the majority of the [[food energy]] required by the ever [[Population growth|increasing]] [[world population|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 Protection]], [[World Resources Institute]], [[World Food Programme]], [[Food and Agriculture Organization]], and [[International Food Information Council]]. They address issues such as [[sustainability]], [[biological diversity]], [[climate change]], [[nutritional economics]], [[population growth]], [[water supply]], and [[Food security|access to food]]. The [[right to food]] is a [[human right]] derived from the [[International Covenant on Economic, Social and Cultural Rights]] ([[ICESCR]]), recognizing the "[[right to an adequate standard of living]], including adequate food", as well as the "fundamental right to be free from [[hunger]]". ==Examples== *[[Cat food]] *Donuts *Pineapples [[Category:Food]] {{Stub}}
