英语自学网

　　Food is any substance, usually composed primarily of carbohydrates, fats,
water and/or proteins, that can be eaten or drunk by an animal or human for
nutrition or pleasure. Items considered food may be sourced from plants, animals
or other categories such as fungus or fermented products like alcohol. Although
many human cultures sought food items through hunting and gathering, today most
cultures use farming, ranching, and fishing, with hunting, foraging and other
methods of a local nature included but playing a minor role.
        　　Most traditions have a recognizable cuisine, a specific set of cooking
traditions, preferences, and practices, the study of which is known as
gastronomy. Many cultures have diversified their foods by means of preparation,
cooking methods and manufacturing. This also includes a complex food trade which
helps the cultures to economically survive by-way-of food, not just by
consumption.
        　　Many cultures study the dietary analysis of food habits. While humans are
omnivores, religion and social constructs such as morality often affect which
foods they will consume. Food safety is also a concern with foodborne illness
claiming many lives each year. In many languages, food is often used
metaphorically or figuratively, as in "food for thought".
