The consumption of kefir, a fermented probiotic milk known to help maintain the balance of good bacteria in the digestive system, can have a positive effect on blood pressure by promoting communication between the intestine and the brain, found a study performed on rats. 19659002] After nine weeks of kefir supplementation, the treated rats had lower levels of endotoxins, toxic substances badociated with an alteration in the cells, lower blood pressure and improved intestinal permeability compared to the untreated group.
In addition, kefir supplementation restored the natural balance of four different bacteria in the intestine and an enzyme in the brain essential for normal function of the nervous system, suggesting that the nervous and digestive systems work together to reduce hypertension, showed the results.
"Our data suggest that the mechanisms badociated with antihypertensive kefir involve communication between the intestinal microbiota and the cerebral axis during hypertension," the study said. The findings will be presented at the annual meeting of the American Physiological Society (APS) at Experimental Biology 2018 in San Diego.
Previous research has shown that an imbalance in the colony of bacteria in the intestine (microbiota) can cause high blood pressure in some people.
Similarly, it has been discovered that probiotics (supplements of living bacteria that are beneficial to the digestive system) reduce blood pressure, but the mechanisms by which this is not clear.
For the study, the team studied three groups of rats – treated, untreated and control – to determine how kefir reduces high blood pressure (hypertension).
