Yogurt, or yoghurt, is a dairy product made by bacterial fermentation of milk. The lactose in the milk becomes lactic acid when it is fermented. Lactic acid acts on the protein in the milk to make yoghurt thick and sour. Yoghurt made from cow's milk is called dairy yoghurt. It is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus salivarius subsp. thermophilus bacteria. The milk is heated to about 80°C to kill any bad bacteria and to change the milk proteins so that they set together instead of becoming curds. After it is cooled to about 45°C, the bacteria culture is added, and the milk is kept at that temperature for 4 to 7 hours to ferment. Soy yoghurt is made from soy milk.
People have been making and eating yoghurt for at least 5,400 years. Today, it is eaten all over the world. A nutritious food which is especially good for your health, it is rich in protein, calcium, riboflavin, vitamin B6 and vitamin B12.
History of the word [change]
The word "yoghurt" comes from Turkish: yoğurt, and is related to the words yoğurmak 'to knead' and yoğun "dense" or "thick". The letter ğ was used to be written as "gh" when people translated the Turkish language.
In Bulgaria, yogurt is called "кисело мляко" (kiselo mlyako), which means "sour milk"; in Serbia, yogurt is also called "кисело млеко" (kiselo mleko), but Serbian yogurt is a thick, milky liquid.
In English, there are many ways to spell the word. In Australia and New Zealand "yoghurt" is the main spelling. In the United Kingdom "yoghurt" and "yogurt" are both used, but "yoghurt" is more common, and "yoghourt" is also sometimes used. In the United States, "yogurt'" is the usual spelling. In Canada, "yogurt" is most common among English speakers, but many brands use "yogourt," because it is correct in both French and English.
The word is usually said with a short o (how to say: /ˈjɒɡət/) in the UK, with a long o (/ˈjoʊɡərt/) in North America, Australia and South Africa, and with either a long or short o in New Zealand and Ireland.
The earliest yoghurts were probably made by wild bacteria and happened by chance.
The oldest writings mentioning yogurt were by Pliny the Elder, who said that some people knew how to thicken the milk into something which was sour but tasty. The use of yoghurt by medieval Turks is recorded in the books Diwan Lughat al-Turk by Mahmud Kashgari and Kutadgu Bilig by Yusuf Has Hajib written in the 11th century. Both texts mention the word "yoghurt" in different sections and describe how it was used. Francis I suffered from a serious diarrhoea which no French doctor could cure. His ally Suleiman the Magnificent sent a doctor, who cured the patient with yoghurt. The grateful French king spread around the information about the food which had cured him.
Until the 1900s, yoghurt was eaten all the time by people in the Russian Empire (and especially Central Asia and the Caucasus), Western Asia, South Eastern Europe/Balkans, Central Europe, and India. Stamen Grigorov (1878–1945), a Bulgarian student of medicine in Geneva, first examined the bacteria in Bulgarian yoghurt. In 1905 he said that it contained a round and a rod-like lactic acid bacteria. In 1907 the rod-like bacteria was called Lactobacillus bulgaricus (now Lactobacillus delbrueckii subsp. bulgaricus). The Russian Nobel laureate biologist Ilya Ilyich Mechnikov, from the Institut Pasteur in Paris, was influenced by Grigorov's work and made a hypothesis that eating yoghurt regularly was the reason why Bulgarian peasants lived for so long. Mechnikov believed that Lactobacillus was needed for good health, and worked to make yoghurt popular through Europe.
In 1919, a Sephardic Jewish entrepreneur named Isaac Carasso started a small yoghurt business in Barcelona and named the business Danone ("little Daniel") after his son. The business later expanded to the United States, where it was called Dannon.
Yoghurt was first brought to the United States by Armenian immigrants Sarkis and Rose Colombosian, who started "Colombo and Sons Creamery" in Andover, Massachusetts in 1929. Colombo Yogurt was first sent around New England in a horse-drawn wagon with the Armenian word "madzoon" written on it. This was later changed to "yogurt", the Turkish name of the product. In the 1950s and 60s yoghurt became very popular in the United States because it was sold as a health food. By the late 20th century yoghurt had become a common food in America and Colombo Yogurt was sold in 1993 to General Mills, who stopped using the brand name in 2010.
How it is good for health [change]
Yoghurt has a lot of protein, calcium, riboflavin, vitamin B6 and vitamin B12 in it. It is better for you than milk is. Many people who are lactose-intolerant can enjoy yoghurt, because much of the lactose in the milk has become lactic acid.
A study in the International Journal of Obesity (11 January 2005) found that eating low-fat yoghurt can help weight loss. In the study, obese people who ate 3 servings of low-fat yoghurt a day lost 22% more weight than the control group who only cut back on calories and did not have extra calcium. They also lost 81% more abdominal fat.
