Kefir is a fermented dairy product rich in probiotics (bacteria and yeasts). In daily life, it is often promoted to improve digestion and reduce bloating. The scientific evidence is moderate: some human studies suggest probiotics can alleviate bloating and IBS symptoms, but results are inconsistent and highly individual. Kefir also contains lactose, which may worsen bloating in lactose-intolerant individuals. If you incorporate kefir into your routine, monitor your personal tolerance. The MyBody-X articles offer general dietary tips but no specific evidence for kefir. Caution: persistent bloating requires medical evaluation to rule out conditions like SIBO or IBS. Kefir can be a healthy addition to a balanced diet, but it is not a cure. The evidence base is mostly practice-oriented and mechanistic, lacking large-scale clinical trials.
