FOOD:

Food is any substance, composed of carbohydrates, water, fats and/or proteins, that is either eaten or drunk by any animal, including humans, for nutrition or pleasure. Items considered food may be sourced from plants, animals or other categories such as fungus. 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. Many traditions have a recognizable cuisine, a specific set of cooking traditions using various spices or combinations of flavors unique to that culture. Other differences include preferences (hot or cold, spicy etc), 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. Some popular types of ethnic foods include: Italian, French, Japanese, Chinese, American, Thai and Indian. Many cultures study the dietary analysis of food habits. While evolutionarily speaking, as opposed to culturally, humans are omnivores, religion and social constructs such as morality, activism or environmentalism will often affect which foods they will consume.
