Kefir is rich in protein, vitamins (especially B12 and K2) and minerals (such as calcium). It contains probiotic bacteria that are beneficial to the digestive system. After bariatric surgery, the digestive system may need to be reorganized and kefir can support this process as a probiotic source. Since it is an easily digestible dairy product, it is generally better tolerated by people with lactose intolerance. It can be a good option as a snack after bariatric surgery. Low-fat, lactose-free kefirs can be preferred.
