Effect of longer-term modest salt reduction on blood pressure

Background A reduction in salt intake lowers blood pressure (BP) and, thereby, reduces cardiovascular risk. A recent meta‐analysis by Graudal implied that salt reduction had adverse effects on hormones and lipids which might mitigate any benefit that occurs with BP reduction. However, Graudal's meta‐analysis included a large number of very short‐term trials with a large change in salt intake, and such studies are irrelevant to the public health...
