High Salt Consumption Tiede_SFlb To 2.3 Million Heart Deaths Worldwide

Eating too much salt contributed to 2.3 million heart-related deaths worldwide in 2010, and 40 percent of those deaths were premature, researchers said.

Fifteen percent of all deaths from heart attacks, stroke and other cardiovascular disease were caused by excessive salt, and most were in lower-income countries, according to a study presented this week at an American Heart Association meeting in New Orleans. The United States ranked 19th of the 30 largest countries studied for deaths due to excess salt.

Excess sodium consumption is a global problem: Seventy-five percent of the world’s population eats nearly twice the daily recommended amount of salt, according to a separate study of 187 countries presented at the meeting. The AHA advises limiting sodium to no more than 1,500 milligrams a day.

In the study linking salt and heart deaths, researchers analyzed 247 surveys on sodium consumption by adults from 1990 to 2010 and determined how the levels of salt people were eating affected cardiovascular disease risks.
