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 being for nutrition or pleasure. Items considered food may be source d 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 which foods they will consume.

Dietary habits are the habitual decisions a person or culture makes when choosing what foods to eat. Although humans are omnivores, many cultures hold some food preferences and some food taboos.

Dietary choices can also define cultures and play a role in religion. For example, only kosher foods are permitted by Judaism, and halal/haram foods by Islam, in the diet of believers. In addition, the dietary choices of different countries or regions have different characteristics. This is highly related to a culture's cuisine.

Food safety is also a concern with foodborn illness claiming many lives each year. In many languages, food is often used metaphorically or figuratively, as in "food for thought".

Some countries list a legal definition of food. These countries list food as any item that is to be processed, partially processed or unprocessed for consumption. The listing of items included as foodstuffs include any substance, intended to be, or reasonably expected to be, ingested by humans. In addition to these foodstuffs drink, chewing gum, water or other items processed into said food items are part of the legal definition of food. Items not included in the legal definition of food include animal feed, live animals unless being prepared for sale in a market, plants prior to harvesting, medicinal products, cosmetics, tobacco and tobacco products, narcotic or psychotropic substances, and residues and contaminants.
