The theory goes that excess salt in your system leads to water retention in the blood, putting pressure on your blood vessels, raising your blood pressure. 'I always told my patients and I have published papers saying whether you have high blood pressure or normal blood pressure, you should reduce your salt intake.' So let's look at the correlation between life expectancy, mortality and salt intake around the world.' I don't know if we can say you can save lives by increasing salt intake, although the paper seems to show that.' Such incremental changes go unnoticed, says Professor MacGregor — 'people's salt intake has fallen and they don't realise it because their salt taste receptors adjust'.
