Kefir

Kefir is a fermented milk drink made by adding kefir grains to milk. The grains, a symbiotic culture of bacteria and yeasts, ferment the milk, creating a tangy, slightly effervescent beverage. It is a traditional drink originating from the Caucasus Mountains.

Kefir is primarily used as a probiotic-rich beverage, often consumed on its own or used in smoothies. Manufacturers may also incorporate it into dairy products like yogurt, cheese, or spreads to add a distinct tangy flavor and beneficial bacteria.

Kefir is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of probiotics, which are live microorganisms thought to benefit gut health. Regulatory bodies like EFSA have evaluated fermented dairy products, but specific health claims are subject to ongoing research and vary by region. Evidence on specific health benefits is still developing.
