Q: Question: Do red wine polyphenols lower peripheral or central blood pressure in high normal blood pressure and hypertension?
Answer: Intake of red wine polyphenols in two different dosages for 4 weeks did not decrease peripheral or central BP in subjects with a high normal or grade 1 hypertension. Our findings do not support the hypothesis that polyphenols account for the suggested cardiovascular benefits of red wine consumption by lowering BP.
A:
no
