Salt is not so dangerous
The new study, refuting the established opinion about the dangers of salt, published the authoritative journal the Lancet.
Its authors, canadian researchers from the research Institute of public health, argue that familiar to many people, the amount of salt intake has nothing to do with health risks.
According to who, the daily consumption of salt in excess of 5 grams per day (one teaspoon) provokes the threat of a breach in the human body, in particular, causing obesity and hypertension. However, the researchers note that these rules are not respected anywhere in the world, and in fact the concept of excessive salt intake should begin not with five grams, and more.
But this does not mean that it is abuse
This conclusion was made by specialists after they have analyzed data obtained during the research project Prospective Urban Rural Epidemiology and health-related 95.7 thousand people at the age from 35 to 70 years from 18 countries. In particular, doctors estimated daily intake of sodium and potassium, height, weight and blood pressure people, the history of their diseases and other information. For the test subjects were followed for eight years.
The results showed that increased sodium intake can increase risk of hypertension and stroke only if that person used more than five grams of sodium per day, or more than 12 grams of salt a day (two teaspoons). On average, people consumed much less salt – 4.77 grams of sodium or less than 3 grams of salt, as scientists have calculated.
“Our study, like other works, shows that at moderate levels of consumption of sodium can be helpful for heart health and blood vessels. It becomes dangerous at very high or very low. Most people’s salt intake is associated with increased risk of cardiovascular disease or death,” stated the authors.
