One in 10 global cardiovascular deaths due to high sodium intake
Excess sodium intake attributable to 1.65 million cardiovascular deaths worldwide
The World Health Organization recommends that adults should consume less than 2 g of sodium per day. This new study finds that sodium intake above this level accounts for almost one in 10 cardiovascular deaths globally each year. The research team, led by Dr. Dariush Mozaffarian, of the Friedman School of Nutrition Science and Policy at Tufts University in Medford, MA, analyzed data from 205 surveys of sodium intake representing approximately 75% of the world's adult population, along with global data on how sodium intake varies by sex, age and country. They also conducted pooled meta-analyses to measure the effects of sodium on blood pressure, and the effects of blood pressure on cardiovascular diseases. They then applied the findings to current global rates of cardiovascular diseases, to estimate how many deaths are caused by sodium intake above 2 g per day. The average worldwide sodium intake was 3.95 g per day - almost double the daily recommendation set by WHO. The global region with the highest sodium overload: Central Asia at 5.51 g per day. The average daily sodium intake in the US was almost 80% higher than the WHO recommendation, at 3.6 g, causing around 58,000 cardiovascular-related deaths in the US each year.
No doubt about it, we're all salt freaks, particularly if we consume fast and highly-processed food. Further or follow-up research needed to determine causes and remedies.

The study did not delve into remedies for high sodium intake; here are a few commonsense tips: http://highbloodpressure.about.com/od/prevention/tp/lower-your-salt-intake.htm
