Kefir is a creamy and tart probiotic drink that's made by adding kefir grains to milk and allowing it to ferment. The grains contain bacteria and yeast.
Kefir grains resemble cooked cauliflower. The bacteria and yeast they contain depend on where the kefir is made. Lactobacillus lactis, Lactobacillus casei, and other Lactobacillus species may be present in kefir. Many of these species can survive traveling through the stomach to the intestinal tract.
People use kefir for hay fever, diarrhea from antibiotics, athletic performance, constipation, Crohn disease, diabetes, high cholesterol, obesity, osteoporosis, and many other conditions, but there is no good scientific evidence to support these uses.
Don't confuse kefir with other fermented dairy products, including fermented milk and yogurt. These are not the same.
