Kefir, Natural exir

Kefir (alternately kefīrs, keefir, kephir, etc), purportedly from either the Turkish "keyif" (joy/pleasure) or "köpür" (milk) froth, foam) or from the Persian "kef" (foam) and "shir" (milk), is a fermented milk drink that originated with shepherds of the Caucasus region, who discovered that fresh milk carried in leather pouches would occasionally ferment into an effervescent beverage. It is prepared by inoculating cow, goat, or sheep's milk with kefir grains. grains are a combination of bacteria and yeasts in a matrix of proteins, lipids, and sugars. This symbiotic matrix forms "grains" that resemble cauliflower. Many different bacteria and yeasts are found in the kefir grains, which are a complex and highly variablecommunity of micro-organisms termed probiotics. Kefir has antimutagenic and antiapoptisis antioxidant properties, and can possibly be used to prevent mutagenic and oxidative damage in the human body One can change the nutrient content by simply fermenting for shorter or longer periods. Kefir has many reputed health benefits. It has antibiotic and antifungal properties. Manystudies, in both animals and humans, have demonstrated immunestimulatingeffects from yogurt varieties that contain live cultures such as Lactobacillus acidophilus and other probiotics (we can say friendly bacteria). The effects observed in humans include an increase in the activity of several types of white blood cells.Supplements of Lactobacillus acidophilus and other friendly bacteria may help protect the intestinal tract from colonization by harmful organisms that can cause local or systemic infection. The effective amount of acidophilus depends on the strain used, as well as the concentration of viable organisms it contains. Infectious diarrhea in children has been successfully reduced with supplements of friendly bacteria such as L. acidophilus. So nowadays keffir has been used in the treatment of a variety of conditions, including metabolic disorders, atherosclerosis, and allergies, tuberculosis, cancer, poor digestion, candidiasis, osteoporosis, hypertension, HIV and heart disease.
