According to the study, a high-sodium diet is only linked to an increased risk of cardiovascular disease in populations of people with high blood pressure. For people with a normal blood pressure, the study found a high-sodium diet was not associated with cardiovascular disease.
The study involved more than 130,000 people from 49 countries.
