==Kefir vs. [[Yogurt]]==
Yogurt is a source of probiotics, the live organisms (including healthy bacteria's) that are naturally found in our digestive tracts. These organisms help stem the growth of harmful bacteria and boost our immune systems. But kefir is an even better source of these helpful little guys — three times the source of yogurt, it's thought. This is because kefir is made by fermenting milk with 10 to 20 different types of bacteria and yeasts, where yogurt is usually just fermented with a handful of types; this leads to a higher probiotic count in the final product.
