Does moderate sodium intake (3-6 g/day) and higher potassium excretion (>1.50 g/day) reduce the risk of death and cardiovascular events compared to other intake levels?
Moderate sodium intake (3-6 g/day) and higher potassium excretion are associated with the lowest risk of mortality and cardiovascular events.
In this study in which sodium intake was estimated on the basis of measured urinary excretion, an estimated sodium intake between 3 g per day and 6 g per day was associated with a lower risk of death and cardiovascular events than was either a higher or lower estimated level of intake. As compared with an estimated potassium excretion that was less than 1.50 g per day, higher potassium excretion was associated with a lower risk of death and cardiovascular events.
