A recent study stated that high salt intake is associated with a doubled risk of heart failure.
The findings showed that people who consume more than 13.7 grams of salt daily may be at two times higher risk of heart failure compared to those consuming less than 6.8 grams.
This salt-related increase in heart failure risk was independent of blood pressure level — an increased level of which is also a risk factor for cardiovascular diseases, the researchers said.
According to World Health Organisation(WHO), as many as 2.5 million deaths could be prevented in a year if people reduced their consumption of salt to its recommended level of 5 grams.
However, most people don’t abide by the standard level and eat about 80 to 140 per cent more than they should in excess. Professor Jousilahti revealed that their study found that eating more than 13.7g a day of sodium chloride doubled the rate of heart failure in the sample participants.
The optimal daily salt intake is probably even lower than 6.8 grams. The World Health Organisation recommends a maximum of 5 grams per day and the physiological need is two-three grams per day.
“The heart does not like the High salt (sodium chloride) intake is one of the major causes of high blood pressure and an independent risk factor for coronary heart disease (CHD) and stroke,” said Pekka Jousilahti, a professor at the National Institute for Health and Welfare, Finland.
The results were presented at the European Society of Cardiology Congress in Barcelona.
