Food is any substance, usually composed of carbohydrates Carbohydrates [α] or saccharides[β] are the most abundant of the four major classes of biomolecules. They fill numerous roles in living things, such as the storage and transport of energy and structural components (e.g., cellulose in plants and chitin in animals). In addition, carbohydrates and their derivatives play major roles in the working, 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 normal 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 chain 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 and water Water is the ubiquitous chemical substance, composed of hydrogen and oxygen, that is essential for the survival of many known forms of life. In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state, water vapor or steam. Water covers 71% of the Earth's surface. On Earth, it, that can be eaten In general terms, eating is the process of consuming food to provide for the nutritional needs of an animal, particularly their energy requirements and to grow. All animals must eat organisms in order to survive: carnivores eat other animals, herbivores eat plants, and omnivores consume a mixture of both; see feeding 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. Items considered food may be sourced from plants, animals or other categories such as fungus A fungus is any 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 and animals. One major difference is that fungal cells have cell walls that 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 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 simply as. 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 encompasses a wide variety of specialties and techniques, including ways to expand the lands suitable for plant raising, by digging water-channels and other forms of irrigation. Cultivation of crops on arable land and the pastoral herding of livestock on rangeland remain at the foundation of agriculture. In the past century there has, 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 large, small or, 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 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, tend to occur subconsciously, without directly thinking consciously about them. Habitual behavior sometimes goes unnoticed in persons exhibiting them, because it is often unnecessary to engage in self-analysis when undertaking in routine tasks. Habituation is an extremely simple form of. While humans are omnivores Omnivores 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 omnivore that many people see every day. Humans are, religion and social constructs such as morality often affect which foods they will consume. Food safety is also a concern with foodborne illness There are two types of food poisoning: food infection and food intoxication. Food infection refers to the presence of bacteria or other microbes which infect the body after consumption. Food intoxication refers to the ingestion of toxins contained within the food, including bacterially produced exotoxins, which can happen even when the microbe claiming many lives each year. In many languages, food is often used metaphorically or figuratively, as in "food for thought".
