Taking probiotics regularly can help lower blood pressure, a new study suggests.
Probiotics, the live microorganisms acquired through yogurt or dietary supplements, have long been believed to help improve health by fighting harmful bacteria and supporting digestion. Previous studies have highlighted countless health benefits associated with probiotics consumption including treating various health conditions like eczema, diabetes, fatty liver disease,vaginal yeast infection, diarrhoea, urinary tract infection, intestinal infections and irritable bowel syndrome.
In the new study, a team of Australian researchers closely monitored 543 adults with high BP. People, who took probiotics for eight weeks, achieved a considerable reduction in both systolic and diastolic blood pressure. Probiotics consumption particularly helped people whose blood pressure was comparatively higher than the others. However, only probiotics that contained multiple bacteria and a daily bacteria volume of 109 or above CFU (colony-forming units) gave these positive results.
“The small collection of studies we looked at suggest regular consumption of probiotics can be part of a healthy lifestyle to help reduce high blood pressure, as well as maintain healthy blood pressure levels,” Dr Sun, lead author and senior lecturer at the Griffith Health Institute and School of Medicine, Griffith University, Queensland in Australia, said in a press release. “This includes probiotics in yogurt, fermented and sour milk and cheese, and probiotic supplements.”
Researchers found that probiotics worked by influencing other factors that influence good health and by improving their function. “We believe probiotics might help lower blood pressure by having other positive effects on health, including improving total cholesterol and low-density lipoprotein, or LDL, cholesterol; reducing blood glucose and insulin resistance; and by helping to regulate the hormone system that regulates blood pressure and fluid balance,” Sun added.
The study has been reported in the journal Hypertension.
