kefir is a tangy, fermented drink made from milk or water, known for its probiotic benefits. It is created by adding kefir grains, which are small clusters of bacteria and yeast, to the liquid. These grains ferment the sugars, resulting in a creamy, slightly effervescent beverage that is rich in nutrients and good for gut health. This versatile drink can be enjoyed on its own or used in smoothies, salad dressings, and baked goods. Many people appreciate kefir for its unique flavor and health benefits, making it a popular choice for those looking to enhance their diet with fermented foods.
