Question

for thousands of years, humans have been eating fermented foods, or foods that have undergone special chemical changes. sour cream and yogurt are two well known fermented foods. sour cream originates from eastern europe and appears in many traditional dishes there. by contrast, yogurt features prominently in middle eastern cuisine. yogurt is high in protein compared to sour cream and contains lots of vitamins. yogurt is often consumed by itself as a snack or even as a drink. sour cream, however, is traditionally used to flavor other foods. it is made from cream, and it has a very high fat content. its sourness comes from bacteria that are added to the cream. these bacteria give sour cream its tangy flavor and thickness. bacteria are also responsible for yogurts flavor and texture.
