The nitrate in beetroot juice helps lower blood pressure.
Researchers from Queen Mary University Of London discovered that drinking beet juice lowered blood pressure two years ago. But now they believe nitrates are the reason why.
People who took part in their study either took nitrate pills or drank beetroot juice. It only took a small amount of juice to have an effect.
Within 24 hours of drinking the juice or taking the supplement, blood pressures decreased.
