Consuming too much salt leads to more than 1.6 million heart disease-related deaths around the world each year, research suggests.

Scientists based the finding on an analysis of 205 surveys of sodium intake in countries representing nearly three-quarters of the world's adult population.

Effects of sodium on blood pressure and cardiovascular disease risk were determined in a separate study of pooled trial data.

The average level of sodium consumption in 2010 was found to be 3.95 grams per day - nearly double the two grammes recommended by the World Health Organisation.
