Food is any substance consumed to provide nutritional support for an organism. 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 to provide energy, maintain life, or stimulate growth.
Historically, humans secured food through two methods: hunting and gathering and agriculture. Today, the majority of the food energy required by the ever increasing population of the world is supplied by the food industry.
|Yeasts are eukaryotic micro-organisms classified in the kingdom Fungi, with 1,500 species currently described estimated to be only 1% of all fungal species. Most reproduce asexually by mitosis, and many do so via an asymmetric division process called budding. Yeasts are unicellular, although some species with yeast forms may become multicellular through the formation of a string of connected budding cells known as pseudohyphae, or false hyphae, as seen in most molds. Yeast size can vary greatly depending on the species, typically measuring 3-4 µm in diameter, although some yeasts can reach over 40 µm.
By fermentation the yeast species Saccharomyces cerevisiae converts carbohydrates to carbon dioxide and alcohols - for thousands of years the carbon dioxide has been used in baking and the alcohol in alcoholic beverages. It is also extremely important as a model organism in modern cell biology research, and is one of the most thoroughly researched eukaryotic microorganisms. Researchers have used it to gather information about the biology of the eukaryotic cell and ultimately human biology. Other species of yeast, such as Candida albicans, are opportunistic pathogens and can cause infections in humans. Yeasts have recently been used to generate electricity in microbial fuel cells, and produce ethanol for the biofuel industry.
Yeasts do not form a single taxonomic or phylogenetic grouping. The term "yeast" is often taken as a synonym for Saccharomyces cerevisiae, but the phylogenetic diversity of yeasts is shown by their placement in two separate phyla, the Ascomycota and the Basidiomycota. The budding yeasts ("true yeasts") are classified in the order Saccharomycetales.

B. 27 May 1975
James Trevor Oliver, MBE, better known as Jamie Oliver and nicknamed The Naked Chef, is an English celebrity chef. He is well known for his role in campaigning against processed foods in British schools. Since his early years, his Essex accent, which is often described as "mockney" or "fake cockney," has become infamous, particularly the use of the hindi word "pukka" (colloquially meaning "brilliant" or "solid", originally "cooked" or "ripe"). Oliver is reported to be worth an estimated £25 million.
is a base sauce in international cuisines, originally French
, composed of varying ratios of flour
), useful for making sauces, and for thickening soups
. It can be cooked to different degrees (white roux, blonde roux or brown roux) depending upon the intended use, and a darker roux (one that has been cooked longer) will also be thicker, but will have less thickening power.

Did you know...
A path of shelled pecans makes its way through a host of unshelled ones. Pecans can be eaten fresh or used in cooking, particularly in sweet desserts, such as the pecan pie, a traditional southern U.S. recipe. Pecans are also a major ingredient in praline candy. The U.S. produces between 80% and 95% of the world's pecans, with an annual crop of 150–200 million kg (300–400 million pounds).
