Too Much Salt Is Dangerous For Heart Patients … But So Is Too Little – Study

November 23, 2011: 12:00 AM EST
A study by Irish and Canadian researchers has confirmed that high salt intake may put people with heart disease or diabetes at increased risk of cardiovascular complications, but has also found that too little salt intake may also put these patients at risk. The study found that moderate salt intake is associated with the lowest risk of cardiovascular events. Higher intake of sodium was associated with an increased risk of stroke, heart attack and other cardiovascular events. And low intake was associated with an increased risk of cardiovascular death and hospitalization for congestive heart failure. According to the researchers, the findings call into question current guidelines for salt intake, which recommend less than 2,300 mg a day.
