More than 25 per cent of the world’s adult population are hypertensive, and it has been estimated that this figure will increase to 29 per cent by 2025. In addition, hypertension causes around 50 per cent of coronary heart disease, and approximately 75 per cent of strokes.
In demonstrating that nitrate is likely to underlie the cardio-protective effect of a vegetable-rich diet, researchers at Barts and The London School of Medicine have discovered that drinking just 500ml of beetroot juice a day can significantly reduce blood pressure.
Led by Professor Amrita Ahluwalia of the William Harvey Research Institute at Barts and The London School of Medicine, and Professor Ben Benjamin of Peninsula Medical School, the research reveals that it is the ingestion of dietary nitrate contained within beetroot juice - and similarly in green, leafy vegetables - which results ultimately in decreased blood pressure.
Previously the protective effects of vegetable-rich diets had been attributed to their antioxidant vitamin content.
