It has long been thought that individuals facing a greater risk of heart disease and stroke would be wise to decrease their daily salt intake to no more than 2.3 grams a day in order to lessen those risks, researchers are now singing a slightly different tune.
After four years of observational studies that included 69,559 individuals who showed no signs of hypertension, researchers concluded that consuming more than seven grams of sodium daily did not increase the risk of heart disease for said group.
However, individuals that lowered their daily sodium intake to less than three grams a day showed a 26% increase of heart disease, stroke, or even death when compared to those consuming four or five grams of salt on daily basis.
Scientists also determined that those 63,559 people with a history of hypertension consuming more than seven grams daily, ended up increasing their risk of heart disease by 23%. Yet there was still a negative impact when decreasing sodium in individuals with hypertension, just as there was with those is seemingly good health. Lowering sodium intake to less than three grams showed a 34% increased risk compared to the same group, with pre-existing hypertension, that consumed four or five grams of salt on a daily basis.
While low sodium intake appears to have concerning effects when it comes to heart health, “It’s important not to rely on blood pressure alone” Andrew Mente, the lead author of the study stated.
