Queen Mary, University of London - N-lightening results

The nitrate content of beetroot juice is the underlying cause of its blood pressure-lowering benefits, research has concluded. Academics from Queen Mary, University of London, found that blood pressure was lowered within 24 hours both in people who took nitrate tablets and people who drank beetroot juice. The study's author, Amrita Ahluwalia, professor of vascular biology at Queen Mary's William Harvey Research Institute, said: "Our previous study two years ago found that drinking beetroot juice lowered blood pressure; now we know how it works."
