Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
The cuisine of the Americas is made up of a variety of food preparation styles.
British cuisine is the specific set of cooking traditions and practices associated with the United Kingdom. British cuisine has been described as "unfussy dishes made with quality local ingredients, matched with simple sauces to accentuate flavour, rather than disguise it." However, British cuisine has absorbed the cultural influence of those that have settled in Britain, producing hybrid dishes, such as the Anglo-Indian chicken tikka masala."
Celtic agriculture and animal breeding produced a wide variety of foodstuffs for indigenous Celts and Britons. Anglo-Saxon England developed meat and savoury herb stewing techniques before the practice became common in Europe. The Norman conquest introduced exotic spices into England in the Middle Ages. The British Empire facilitated a knowledge of India's elaborate food tradition of "strong, penetrating spices and herbs". Food rationing policies, put in place by the British government during wartime periods of the 20th century, are said to have been the stimulus for British cuisine's poor international reputation. It has been claimed, contrary to popular belief, that people in southern England eat more garlic per head than the people of northern France.
A global cuisine is a cuisine that is practiced around the world. A cuisine is a characteristic style of cooking practices and traditions, often associated with a specific region, country or culture. To become a global cuisine, a local, regional or national cuisine must spread around the world, its food served world-wide. There have been significant improvements and advances during the last century in food preservation, storage, shipping and production, and today many countries, cities and regions have access to their traditional cuisines and many other global cuisines.
A dairy product is food produced from the milk of mammals. Dairy products are usually high energy-yielding food products. A production plant for the processing of milk is called a dairy or a dairy factory. Apart from breastfed infants, the human consumption of dairy products is sourced primarily from the milk of cows, yet goats, sheep, yaks, horses, camels, and other mammals are other sources of dairy products consumed by humans. Dairy products are commonly found in European, Middle Eastern, and Indian cuisine, whereas aside from Mongolian cuisine they are little-known in traditional East Asian cuisine.
Ice cream (derived from earlier iced cream or cream ice) is a frozen dessert usually made from dairy products, such as milk and cream and often combined with fruits or other ingredients and flavours. Most varieties contain sugar, although some are made with other sweeteners. In some cases, artificial flavourings and colourings are used in addition to, or instead of, the natural ingredients. The mixture of chosen ingredients is stirred slowly while cooling, in order to incorporate air and to prevent large ice crystals from forming. The result is a smoothly textured semi-solid foam that is malleable and can be scooped.
The meaning of the phrase "ice cream" varies from one country to another. Phrases such as "frozen custard", "frozen yogurt", "sorbet", "gelato" and others are used to distinguish different varieties and styles. In some countries, such as the United States, the phrase "ice cream" applies only to a specific variety, and most governments regulate the commercial use of the various terms according to the relative quantities of the main ingredients. Products that do not meet the criteria to be called ice cream are labelled "frozen dairy dessert" instead. In other countries, such as Italy and Argentina, one word is used for all variants. Analogues made from dairy alternatives, such as goat's or sheep's milk, or milk substitutes, are available for those who are lactose intolerant, allergic to dairy protein, or vegan. The most popular flavours of ice cream are vanilla and chocolate.
