Red beetroot (Beta vulgaris) is a rich source of phytochemicals that may provide health benefits to individuals who consume it regularly as part of a healthy diet. Red beetroot has been evidenced to contain betanin, phenolic compounds, saponins, fibre, vitamins and minerals. One nutrient that is of particular nutritional interest is the nitrate content of the plant. Nitrates are thought to possess beneficial effects with regard to protection from cardiovascular disease. Nitrate and its metabolites, found in all plants, are precursors for nitric oxide in humans and animals. Increased synthesis of nitric oxide may have beneficial effects on cardiomyocytes and may improve endothelial function through a relaxation of endothelial tissues. This later effect may reduce the stiffness in arteries that can be a significant cause of high blood pressure, and thereby dietary nitrates may significantly lower systolic and diastolic blood pressure. Beetroot is a rich source of dietary nitrates and so may confer protection from cardiovascular disease.
