Dairy Intolerance - milk protein
49 different bacterial strains in kefir ALL found to break down dairy proteins: Quote " The results showed that all (49) strains hydrolysed casein"
EVIDENCE FOR PROTEOLYTIC ACTIVITY OF LACTOBACILLI ISOLATED FROM KEFIR GRAINS
Dairy Intolerance - lactose
Live bacteria in kefir promotes "auto-digestion" : Quote " Because kefir improved lactose digestion and tolerance in this study, its use may be another potential strategy for overcoming lactose intolerance"
KEFIR IMPROVES LACTOSE DIGESTION AND TOLERANCE IN ADULTS WITH LACTOSE MALDIGESTION
Microbes in kefir proven to boost lactose digestion: Quote " These results give direct evidence of an enhanced lactose digestion and absorption in native fermented milk products due to the microbial β-galactosidase activity [of kefir]"
ENHANCEMENT OF INTESTINAL HYDRYOLYSIS OF LACTOSE BY MICROBIAL β-GALACTOSIDASES (EC188.8.131.52) OF KEFIR
Researchers say that the human gut microbiota has an important role in regulating body weight. Quote " ... microbial genes sort the lean from the obese with 90% accuracy, whereas looking at human genes yields the right answer only 58% of the time "
