A study of 20,995 people in rural China who had a history of stroke or were 60 and over with high blood pressure were provided with either regular salt or a reduced sodium salt containing 25% potassium chloride.
It was discovered that those taking the reduced sodium salt had fewer stroke events per 1,000 person-years (29.14) than those who were eating regular salt (33.65).
In the case of heart attacks, there were 49.09 events per 1,000 person-years among those consuming the reduced sodium salt as opposed to 56.29 events for salt-eaters (1).
The study’s authors concluded:
“Among persons who had a history of stroke or were 60 years of age or older and had high blood pressure, the rates of stroke, major cardiovascular events and death from any cause were lower with the salt substitute than with regular salt” (2)
In another article the lead author indicated:
“The trial result is particularly exciting because salt substitution is one of the few practical ways of achieving changes in the salt people eat” (3)
Suölo® Reduced Sodium Sea Salt is 50% reduced sodium compared to regular salt and this is achieved by using Smart Salt® technology that uses potassium chloride and magnesium chloride. A clinical trial with foods made using this technology, in people with moderately raised blood pressure, has indicated a significant reduction in blood pressure in just an 8 week intervention (4).
However what we do know is that too much potassium chloride can taste bitter and metallic. Suölo® Reduced Sodium Sea Salt contains around 25% potassium chloride, like the Chinese study, but is balanced with another important heart mineral, magnesium. This balance of salts ensures a great tasting product with 50% less sodium.
The new landmark study indicates that replacing salt with a common salt substitute could prevent thousands of strokes and heart attacks each year.
