CNN reports that investigators "instructed 67 older men at risk for heart disease to consume the same beverage every day for one month at a time: red wine (about two glasses), non-alcoholic red wine, or gin (about two shots)." The researchers found that "the daily doses of alcoholic red wine and of gin - which doesn't contain polyphenols - had no discernible effect on blood pressure." However, "when the men drank the non-alcoholic red wine, their systolic and diastolic blood pressure fell by an average of 6 and 2 points, respectively, over the course of the month."
The nonalcoholic wine drinkers also showed increased levels of nitric oxide - a molecule in the blood that previous studies have linked with improving blood-vessel health and lowering blood pressure.
The results of the study were largely the same when excluding individuals with hypertension and those taking antihypertensives, the researchers reported.
