Kefir—popular in many cuisines across the world—is a type of fermented food. With a consistency akin to yoghurt, it is packed with probiotics and is touted for its benefits to the gut and digestive system. It is made by fermenting milk with kefir grains (a combination of bacteria and yeast). Over a 24-hour period, these microorganisms ferment the milk's sugars, producing kefir while leaving the grains reusable for future batches. The process also gives it a rich, tart-like flavour. Here Are 9 Health Benefits Of Kefir1. A Rich Source of Essential NutrientsOriginating from Eastern Europe and Southwest Asia, kefir derives its name from the Turkish word "keyif," meaning a sense of well-being after eating. Kefir is highly nutritious and a one-cup serving of low-fat kefir provides:Protein: 9 gramsCalcium: 36% of the daily value (DV)Phosphorus: 20% of DVVitamin B12: 29% of DVRiboflavin (B2): 25% of DVMagnesium: 7% of DVVitamin D: 12% of DVBesides, it also boasts of a variety of bioactive compounds, including organic acids and peptides that contribute to its health benefits. Additionally, dairy-free versions of kefir can be prepared using coconut water, coconut milk, or other sweet liquids, although their nutrient content differs from traditional dairy-based kefir.2. A More Potent Probiotic Than YogurtProbiotics—beneficial microorganisms that support digestion, weight management, and mental well-being—are abundant in kefir. While yogurt is a well-known probiotic food, kefir offers a more diverse and potent source, containing up to 61 strains of bacteria and yeast. This variety makes kefir a richer probiotic source compared to other fermented dairy products, which typically contain fewer strains and lack yeast.3. Natural Antibacterial PropertiesKefir contains probiotics that help combat infections, including Lactobacillus kefiri, a strain unique to kefir. Research indicates that this probiotic can inhibit the growth of harmful bacteria such as Salmonella, Helicobacter pylori, and E. coli. Additionally, kefiran, a carbohydrate found in kefir, possesses antibacterial properties that contribute to its protective effects.4. Supports Bone Health and Reduces Osteoporosis RiskOsteoporosis, a condition characterized by weakened bones and an increased risk of fractures, is a major health concern, especially among older women. Calcium intake plays a crucial role in bone health, and kefir is an excellent source of this essential mineral. Full-fat kefir also contains vitamin K2, which is vital for calcium metabolism. Animal studies suggest that kefir enhances calcium absorption in bone cells, leading to improved bone density and reduced fracture risk.5. Potential Cancer-Fighting PropertiesCancer, one of the leading causes of death worldwide, occurs due to uncontrolled cell growth. Probiotics in fermented dairy products may help combat tumor development by stimulating the immune system. Laboratory studies suggest that kefir extract can significantly reduce the growth of human breast cancer cells, outperforming yogurt extract. However, more human studies are needed to confirm these findings.6. Aids Digestion and Alleviates Gastrointestinal IssuesKefir’s probiotic content helps restore the balance of gut-friendly bacteria, making it an effective remedy for digestive problems, including various forms of diarrhea. Research suggests that probiotics can help manage conditions like irritable bowel syndrome (IBS) and ulcers caused by H. pylori infection. Consequently, kefir may be beneficial for those experiencing digestive discomfort.7. Naturally Low in LactoseDairy products contain lactose, a natural sugar that many adults struggle to digest due to lactose intolerance. The fermentation process in kefir reduces lactose content by converting it into lactic acid, making it easier to digest. Kefir also contains enzymes that further aid in breaking down lactose, making it a more tolerable option for individuals with lactose sensitivity. For those seeking a completely lactose-free alternative, kefir can be made using coconut water, fruit juice, or other non-dairy beverages.8. May Help Reduce Allergy and Asthma SymptomsAllergic reactions stem from inflammatory immune responses, which can lead to conditions like asthma. Animal studies indicate that kefir can suppress inflammation related to allergies and asthma. While promising, further human research is needed to establish its effectiveness in managing these conditions.
