Food is any substance[1] 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.
Historically, humans secured
food through two methods: hunting
and gathering and agriculture.

energy required by the ever increasing population
of the world is supplied by the food
industry. อ่านเพิ่มเติม
