Food is any substance, usually comprised primarily of carbohydrates, fats, and/or proteins, that can be consumed by animals (including humans) for nutrition or pleasure. Almost all foods are of plant or animal origin. Many cultures have a recognizable cuisine, a specific set of cooking traditions, preferences, and practices.

The study of food is called food science. In English, the term food is often used metaphorically or figuratively, as in food for thought.

Human eating habits

Historical development

Humans are omnivorous animals that can consume both plant and animal products. Evidence suggests that early humans employed hunter-gatherer techniques as their primary method of food collection. This involves combining stationary plant and fungal food sources (such as fruits, grains, roots, and mushrooms) with mobile animals which must be hunted and killed in order to be consumed. Additionally, it is believed that humans have used fire to prepare food prior to eating since their divergence from Homo erectus, possibly even earlier.
