Maintaining a moderate intake of sodium each day is the healthiest choice for everyone, a study says.

According to researchers cutting down one's daily salt intake could actually be harmful to its body, reported Health news.

A recent global study conducted by researchers of the Population Health Research Institute of McMaster University and Hamilton Health Sciences found low-sodium diets actually increase the risk of cardiovascular disease and death compared to diets with average sodium consumption.

If the body doesn't get enough of it, a variety of health problems could result, including an increased risk of heart attack and stroke.

According to the study, a high-sodium diet is only linked to an increased risk of cardiovascular disease in populations of people with high blood pressure. For people with a normal blood pressure, the study found a high-sodium diet was not associated with cardiovascular disease.

The study involved more than 130,000 people from 49 countries. It looked specifically at how the relationship between sodium intake and heart disease, stroke and death differed in people with high blood pressure as compared to those with normal blood pressure.

Mente said previous research that favoured low-sodium diets were based on assumptions about the relationship between blood pressure and sodium levels.

"It appears that low sodium truly is harmful and we need to be cautious before recommending low levels for the entire population," he said.
