A recent study confirmed that salt intake tends to increase blood pressure and found that, as a result, people with high blood pressure who significantly cut their salt intake during the study had lower blood pressure by the end of the study
However, it was also found that some people who had very high salt intake both before and throughout the study maintained very low blood pressure
Study participants with high blood pressure who cut their salt intake only slightly during the study did not have significantly lower blood pressure by the end of the study.
