Salt Restriction Does Not Lower High Blood Pressure Very Much
The issue of salt restriction for lowering blood pressure or heart disease may be the most controversial diet and health topic today. Many people have reduced their salt intake with the hope it will be good for them. A new analysis of several previously published studies suggests not much benefit comes from salt restriction. From analysis of eleven trials with over 3,500 subjects, the researchers found that blood pressure changes were minimal (not more than one mm of mercury) and there was no effect on any cardiovascular events or death. They concluded that reducing salt intake may help hypertensive people stop their medication but that there are no other benefits.
