1. What Exactly Is Kefir and Where Does It Come From?
Kefir is a fermented beverage traditionally made using kefir grains, which are not actually grains but rather a symbiotic culture of bacteria and yeasts (SCOBY). These grains are added to milk, and over a period of about 24 hours, the microorganisms ferment the milk, creating kefir. According to research from the National Library of Medicine, kefir has been shown to antagonize pathogens and reduce proinflammatory cytokine production. The origins of kefir can be traced back to the North Caucasus Mountains.
