Take health advice with a pinch of salt, says study
Reducing salt in the diets of the general population may not have an overall positive health impact, according to a review of more than 160 scientific studies published yesterday, writes Kate Kelland.
Researchers in the 'American Journal of Hypertension' and the 'Cochrane Library' journal said the review added to evidence suggesting officials should re-evaluate policies advising everyone to eat less salt.
The review -- which collated the findings of 167 previous studies -- found that while cutting down on salt reduced blood pressure in people who have normal or high blood pressure, it also caused increases in some hormones and other compounds that can adversely affect people's heart health.
High blood pressure, or hypertension, is one of the leading causes of strokes, heart attacks and other cardiovascular diseases.
