Sodium consumption causes 1.6 million deaths per year.

salt-300x118A study analyzing across 187 countries found that high intake, of more than 2,000 mg per day, caused 1.6 million cardiovascular-related deaths per year. The study was published in the New and reveals the extent of the damage that high (salt) intake can cause to the human body.

The study consisted of analyzing existing data from 205 surveys of intake. The impact of on blood pressure and corresponding cardiovascular disease was determined separately in a pooled meta-analyses, differentiated by age and race.

The research findings were combined with current rates of cardiovascular diseases around the world to estimate the numbers of cardiovascular deaths attributable to above 2.0g per day. On average the level of global in 2010 was 3.95g per day, nearly double the 2.0g recommended by the . All regions of the world were above recommended levels, with regional averages ranging from 2.18g per day in sub-Saharan to 5.51g per day in Central Asia. In their meta-analysis the researchers found that reduced intake lowered blood pressure in all adults, with the largest effects identified among older individuals, blacks, and those with pre-existing high blood pressure.

“These 1.65 million deaths represent nearly one in 10 of all deaths from cardiovascular causes worldwide. No world region and few countries were spared,” added Mozaffarian, who chairs the Global Burden of Diseases, , and Chronic Disease Expert Group, an international team of more than 100 scientists studying the effects of on health and who contributed to this effort. “These new findings inform the need for strong policies to reduce dietary in the United States and across the world.”

In the United States, average daily intake was 80 percent higher than the amount recommended by the . Nearly 58,000 cardiovascular deaths each year in the United States were attributed to daily greater than 2.0g.
