'''Yogurt''' (or '''yoghurt''') is a kind of fermented [[cow]]'s [[milk]]. It is created by the voluntary introduction of live [[culture]]s, such as L. acidophilus, into [[milk]] [[product]]s. The bacteria convert [[lactose]] and [[galactose]] into the distinctive yogurt product. America, Europe, and other countries differ in their regulations for what is a healthy amount of culture.

Yogurt is sometimes sweetened with sugar, raisins, [[rose water]], or fruit. It is a refreshing snack that is naturally low in [[calorie]]s and [[trans fat]]. It can be used as a substitute for sour cream in many recipes.
