Effects of Low Salt Diet Versus High Salt Diet on Blood Pressure

High blood pressure is a global public health problem in developed and developing countries including Pakistan. Various studies conducted around the world have linked salt intake to variation in the blood pressure.However, definite conclusions are lacking and the exact role of dietary salt in salt-blood pressure relationship remains controversial. While clinical practice guidelines recommend dietary salt restriction for lowering blood pressure, the relationship of salt with blood pressure has not been tested in the Pakistani population. Therefore, the efficacy of dietary salt restriction on blood pressure of this population remains to be determined. The study aims to determine the relationship between dietary salt intake and blood pressure in Pakistani population. It is hypothesized that alteration in the dietary salt intake demonstrates significant changes in the Systolic BP.
