Keep salt intake down to 3/4 of a teaspoon per day: American Heart Association
A simple measure that could go a long way in enhancing public health — limit salt intake to less than 1,500 mg or about three-fourths of a teaspoon each day — is the subject of an advisory to Americans. The American Heart Association (AHA) has issued an advisory based on a thorough review of recent lab, animal, observational and clinical studies. This advisory is meant not only for people with medical conditions, but also for perfectly healthy people.
A limited salt intake would significantly reduce the risk of high blood pressure (BP), heart disease and stroke. ”Our recommendation is simple in the sense that it applies to the entire US population, not just at-risk groups,” said Nancy Brown, AHA’s chief executive officer, the AHA journal Circulation reports. BP affects more than 76 million adults in the US alone and one billion people worldwide, besides being a major cause of cardiovascular disease, globally, according to a Tulane University statement.
“People should not be swayed by calls for a change in sodium (salt) intake recommendations based on findings from recent studies,” says Paul K. Whelton, professor of global public health at the Tulane University School of Public Health and Tropical Medicine, New Orleans, who led the study. ”Our detailed review of these studies identified serious methodological weaknesses, which limit the value of these reports in setting or revising sodium intake policy,” adds Whelton.
“Our focus should be on finding effective ways to implement, not change, the existing American Heart Association policy on sodium intake,” adds Whelton. Yet, most US adults and children consume sodium far in excess of their physiological needs and guideline recommendations — with an average daily intake more than 3,400 mg per day.
Most of the sodium consumed is hidden in processed and prepared foods. AHA advocates improved nutritional labelling of sodium content and stringent limits on sodium in all foods — fresh, processed and prepared.

‘Thin placenta at birth doubles risk of heart failure’
Children with a thin placenta at birth have double the chances of dying from a sudden heart failure, warns a leading British physician. A thin placenta can hit the quality of a baby’s foetal development by reducing the flow of nutrients between mother and child, and this can affect the way the heart develops. David Barker, physician and professor of clinical epidemiologist at the University of Southampton, said it was crucial the characteristics of the placenta were recorded.
“We should routinely note the measurements after birth. We know the thicker the placenta the better, and that a thin placenta is associated with sudden death,” adds Barker, the Daily Mail reports. At a meeting in the Parliament coming Tuesday, experts will discuss whether to introduce a national screening programme to identify young people at risk of cardiac arrest.
Shadow health secretary Andy Burnham said: “It feels as if more youngsters than ever are being affected.”
