A new study conducted at the McMaster University, Ontario, Canada, has shown that an average salt consumption, which is between one and half teaspoons daily, will not constitute a health risk. But it adds that a quantity that exceeds five grammes, or two and half teaspoons, of salt may be quite dangerous for the heart.
The study also showed that even for those who consumed too much salt, the health risk would be eliminated if people improved the quality of their diets by eating fruits, vegetables, dairy foods, potatoes and other potassium-rich foods.
The authors of the research focused on 94,000 people, aged between 35 and 70, for an average of eight years in some communities from 18 countries around the world and found there was an associated risk of cardiovascular disease and strokes only where the average intake was greater than five grammes of sodium a day.
“The World Health Organisation recommends the consumption of fewer than two grammes of sodium-chloride, that is one teaspoon of salt a day, as a preventative measure against cardiovascular disease, but there is little evidence in terms of improved health outcomes that individuals ever achieve at such a low level,” said Andrew Mente, first author of the study.
