Salt & Our Health


More doubt cast on the salt RDA


In a recent health study, researchers at the Emory University found that salt intake did not increase the risk of cardiovascular disease or heart failure among older adults without prior cardiovascular problems.

Published in Jama Internal medicine, the study sampled 2,642 adults between 71-80, who over a 10 year period reported their own salt intake via a questionnaire.

The results of the study suggest that sodium has a lesser impact on mortality and cardiovascular distress than health professionals previously thought.

The weakness of such a study is that the results were self reported. However, to cite just 2 other scientific investigations with similar findings:  in 2013 the Institute of Medicine in America published a report concluding that there’s no evidence to support current efforts to lower sodium consumption to less than 2,300 mg/day and The New England Journal of Medicine published findings that cast doubt over the current recommendations.

At the heart of the RDA debate is the need for stronger evidence from rigorous controlled trials testing the effects of sodium intake. Conflicting studies cause confusion over a recommended daily allowance which is outdated and ignores studies suggesting that too little salt is harmful. We encourage people to question the low salt strategy laid out by the Government and apply common sense in relation to their own health and their own salt intake levels.
