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 carbohydrates, fats,proteins, vitamins, or minerals. The substance is
ingested by an organism and assimilated by the organism's cells in an effort to
produce energy, maintain life, or stimulate growth.
Historically,
people secured food through two methods: hunting and
gathering, andagriculture. Today, most of the food energy consumed by the world
population 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 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."
