Researchers studied 55 women (some pregnant, some not, some with high blood pressure, some without) to see how their mouth bacteria and nitrate-processing ability relate to blood pressure changes after eating nitrate-rich food.
Scientific Claim
The study included 55 women, both pregnant and non-pregnant, with or without hypertension, to investigate the relationship between oral microbiota, nitrate-reducing capacity, and blood pressure response to dietary nitrate.
Original Statement
“Participants recruited for this study were both pregnant and non-pregnant women, with or without hypertension (N=55). Following an overnight fast, plasma, saliva and tongue scraping samples were collected for measurement of nitrate/nitrite concentrations, oral nitrate-reductase (NaR) activity and microbiota profiling using 16S rRNA gene sequencing.”
