If you have high blood pressure, just drink some beetroot juice. It can bring down the pressure level within 24 hours, and it's a proven way for people looking for a drugs-free approach. Researchers have discovered that nitrate in the juice is the active ingredient that can lower blood pressure. It increases gas nitric oxide levels in the blood that, in turn, reduce pressure. The researchers, from Queen Mary University of London, say that just 250ml of beetroot juice is enough to reduce blood pressure, and the amount is sufficient to lower even high levels. They are hoping that the juice can become a recognised therapy in medicine, as it's a cost-effective solution at a time when healthcare is looking to reduce costs.
