What is the difference between kefir and yogurt?

The main difference between kefir and yogurt stems from the types and amount of probiotic bacteria they contain. Kefir usually contains three times as much probiotic cultures as yogurt, depending on the brand. Kefir also has a thinner consistency and can be consumed as a beverage.

To make yogurt, milk is fermented with only a few types of probiotic yeasts and bacteria, while kefir is made with 10 to 20 types. Probiotics are believed to strengthen the immune system and stop the spread of bad bacteria. Probiotics are live organisms, such as yeast or bacteria, found in the digestive tract's intestinal flora.
