Kefir
Kefir is a fermented milk drink, similar to a thinner version of yogurt, originated from the Caucasus Mountains in Eastern Europe. It is known for its distinct tangy flavor and slight carbonation due to the fermentation process. Kefir is rich in probiotics and nutrients, making it a healthy beverage option that may aid digestion and boost immunity. It is also high in protein, calcium, and B vitamins. Kefir is often consumed plain but can also be used in recipes as a substitute for yogurt or milk. It's available in various flavors, including plain, strawberry, and blueberry.
