Yogurt (or yoghurt) is a kind of fermented milk produced by cows. It is created by the voluntary introduction of live cultures into milk products. The bacteria convert lactose and galactose into the distinctive yoghurt flavor. America, Europe, and other countries differ in their regulations for what is a healthy amount of culture.
Yogurt is a key part of the diet in places such as Mongolia (where it is made from goat or yak milk). It is important to many other cultures worldwide.
Yoghurt is usually sweetened with sugar, raisins, rose water, or fruit. It is a refreshing snack that is naturally low in calories and trans fat.
It was developed by the Bulgarians in the 11th century A.D., and brought to America by Hispanics in the early 20th century.
