Food is any substance, usually composed of carbohydrates A carbohydrate is an organic compound with general formula Cmn, that is, consisting only of carbon, hydrogen and oxygen, the last two in the 2:1 atom ratio. Carbohydrates can be viewed as hydrates of carbon, hence their name, fats Fats consist of a wide group of compounds that are generally soluble in organic solvents and largely insoluble in water. Chemically, fats are generally triesters of glycerol and fatty acids. Fats may be either solid or liquid at room temperature, depending on their structure and composition. Although the words "oils", "fats",, proteins Proteins are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded and water Water is a ubiquitous chemical substance that is composed of hydrogen and oxygen and is vital for all known forms of life, that can be eaten Eating is the process of ingesting food to provide for an animal's nutritional needs, particularly for energy and growth. All animals must eat organisms in order to survive: carnivores eat other animals, herbivores eat plants, and omnivores consume a mixture of both or drunk Drinking is the act of consuming water through the mouth. Water is required for many of life’s physiological processes. Both excessive and inadequate water intake are associated with health problems by an animal, including humans, for nutrition Nutrition is the provision, to cells and organisms, of the materials necessary (in the form of food) to support life. Many common health problems can be prevented or alleviated with a healthy diet or pleasure.[1] Items considered food may be sourced from plants Plants are living organisms belonging to the kingdom Plantae. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The scientific study of plants, known as botany, has identified about 350,000 extant species of plants, defined as seed plants, bryophytes, ferns and fern allies. As of 2004,, animals Animals are a major group of mostly multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also or other categories such as fungus A fungus is a member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. The Fungi (pronounced /ˈfʌndʒaɪ/ or /ˈfʌŋɡaɪ/) are classified as a kingdom that is separate from plants, animals and bacteria. One major difference is that fungal cells have cell or fermented products like alcohol Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a powerful psychoactive drug, best known as the type of alcohol found in alcoholic beverages and in modern thermometers. Ethanol is one of the oldest recreational drugs. In common usage, it is often referred to. Although many human cultures sought food items through hunting and gathering A hunter-gatherer society is one whose primary subsistence method involves the direct procurement of edible plants and animals from the wild, foraging and hunting without significant recourse to the domestication of either. Hunter-gatherers obtain most from gathering rather than hunting; up to 80% of the food is obtained by gathering. The, today most cultures use farming Agriculture is the production of food and goods through farming. Agriculture was the key development that led to the rise of human civilization, with the husbandry of domesticated animals and plants creating food surpluses that enabled the development of more densely populated and stratified societies. The study of agriculture is known as, ranching A ranch is an area of landscape, including various structures, given primarily to the practice of ranching, the practice of raising grazing livestock such as cattle or sheep for meat or wool. The word most often applies to livestock-raising operations in the western United States and Canada, though there are ranches in other areas. People who own, and fishing Fishing is the activity of catching fish. Fish are normally caught in the wild. Techniques for catching fish include hand gathering, spearing, netting, angling and trapping, with hunting Hunting is the practice of pursuing living animals for food, recreation, or trade. In present-day use, the term refers to lawful hunting, as distinguished from poaching, which is the killing, trapping or capture of the hunted species contrary to applicable law. The species which are hunted are referred to as game and are usually mammals and, foraging Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment in which the animal lives. Foraging theory considers the foraging behavior of animals in reference to the payoff that an animal obtains from different foraging options. Foraging theory predicts that the foraging options and other methods of a local nature included but playing a minor role.
Most traditions have a recognizable cuisine Cuisine is a specific set of cooking traditions and practices, often associated with a specific culture. It is often named after the region or place where its underlining culture is present. A cuisine is primarily influenced by the ingredients that are available locally or through trade. Religious food laws can also exercise a strong influence on, a specific set of cooking Cooking is the process of preparing food by applying heat. Cooks select and combine ingredients using a wide range of tools and methods. In the process, the flavor, texture, appearance, and chemical properties of the ingredients can change. Cooking techniques and ingredients vary widely across the world, reflecting unique environmental, economic, traditions, preferences, and practices, the study of which is known as gastronomy Gastronomy is the study of the relationship between culture and food. It is often thought erroneously that the term gastronomy refers exclusively to the art of cooking , but this is only a small part of this discipline; it cannot always be said that a cook is also a gourmet. Gastronomy studies various cultural components with food as its central. 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 Habits are routines of behavior that are repeated regularly and tend to occur subconsciously, without one's directly thinking consciously about them. Habitual behavior often goes unnoticed in persons exhibiting it, because a person does not need to engage in self-analysis when undertaking routine tasks. Habituation is an extremely simple form of. While humans are omnivores Omnivores (from Latin: omni all, everything; vorare to devour) are species that eat both plants and animals as their primary food source. They are opportunistic, general feeders not specifically adapted to eat and digest either meat or plant material exclusively. Pigs are one well-known example of an omnivore. Crows are another example of an, religion and social constructs such as morality In its "descriptive" sense, morality refers to personal or cultural values, codes of conduct or social mores that distinguish between right and wrong in the human society. Describing morality in this way is not making a claim about what is objectively right or wrong, but only referring to what is considered right or wrong by people. For often affect which foods they will consume. Food safety is also a concern with foodborne illness Foodborne illness is any illness resulting from the consumption of contaminated food claiming many lives each year. In many languages, food is often used metaphorically or figuratively, as in "food for thought".
