How does salt contribute?
Raised blood pressure is a major cause of cardiovascular disease, responsible for 62% of stroke and 49% of coronary heart disease. Salt is the major factor that increases blood pressure and is therefore responsible for many strokes and heart attacks every year. It was estimated that a reduction of 6 g of salt per day would reduce stroke by 24% and coronary heart disease by 18%. This would prevent approximately 35,000 stroke and CHD deaths a year in the UK and approximately 2.5 million deaths worldwide.
