High salt intake is associated with increased cardiovascular disease risk, primarily mediated through elevated blood pressure, although the optimal low level of consumption remains debated.
Reduce your salt intake to help lower your blood pressure, which is the leading cause of heart disease. While there is debate on the exact optimal amount, high salt intake is consistently linked to higher blood pressure and more heart disease deaths. Focus on avoiding processed foods, which are major sources of salt.
For salt intake, there is evidence from trials for adverse effects on blood pressure, ie, higher salt intake is associated with higher blood pressure... Evidence for increased risk of CVD events and deaths associated with high salt intake, however, come from prospective studies... As a result, there is broad agreement about the CVD harms of high levels of salt use but debate continues about the optimal low levels of consumption.
Why this rating
Strong trial evidence for BP effects, but prospective study evidence for CVD events has limitations regarding measurement error and reverse causation.
