Salt is necessary for our body, but when it is ingested in excessive amounts, it can easily do more harm than good, so it is necessary to control salt intake and stay within the daily recommended amount.
Data collected in the USA show that subjects who eat on their own add only 5% of their total daily salt intake during meals.
The rest of the daily intake of salt is related to the consumption of processed food and food prepared in restaurants, according to the findings of a one-year monitoring of the diet of 450 respondents aged 18 to 74.
All in all, about 90% of the salt ingested each day is consumed through food that is not prepared at home, published the expert magazine Circulation.
According to the recommendations in force in the USA, the daily intake of salt should be limited to 2300 milligrams.
More than 80% of Americans consume significantly higher amounts of salt than recommended, warn researchers from the University of Minnesota.
Reducing salt intake is associated with a reduced risk of high blood pressure and prevention of heart disease.
