Having probiotics (found in live yogurt, fermented and sour milk, probiotic cheese, probiotic supplements, drinks, miso soup and other foods) has a modest effect on lowering blood pressure, according to the results of a study analysing other studies on the subject (a meta-anaysis)
Better reductions were seen in people who had higher blood pressure and who took multiple probiotics. Taking probiotics for longer was more beneficial.
“However, even a small reduction of blood pressure may have important public health benefits and cardiovascular consequences,” states Dr Saman Khalesi (Griffith University, Australia) in the article published July 21 in Hypertension.
Just a small reduction in blood pressure was associated with a 22% relative reduction in risk of cardiovascular mortality, MI, or stroke.
