Studies show that frequent additions of salt to the diet shorten lifespan
We know that overdose of salt is not very healthy, but since all processed foods contain high levels of salt, we specifically measure how much salt is harmful to our health. Is difficult. A research team led by Professor Lu Qi of Tulane University in New Orleans, Louisiana, focused on 'how much salt is added when eating' as an indicator of how much salt a person likes. The we.

This study was published in the European Heart Journal .
The research team obtained answers from 501,379 UK Biobank participants on 'how much salt should be sprinkled when eating, except when cooking,' regarding the frequency of salt addition, early mortality rate, and life expectancy. I checked the relevance.
The results showed that the higher the frequency of salt addition, the higher the spot urinary sodium concentration or 24-hour urinary sodium excretion, and the risk of premature death was 28% higher, life expectancy was 2 years or more for men and women. It turns out that it will be shorter than a year.
About 70% of the sodium intakes of the Western people surveyed are from processed foods and cooked foods, and 8 to 20% are added at the table. Many processed foods contain high levels of salt and are difficult to track accurately because direct measurements by urinalysis do not always provide data that indicate overall intake, but the research team said. The analysis focused on 'addition of salt' as an indicator of whether people prefer salty foods.
Following the findings, Professor Lu Qi, who led the study, could not explicitly rule out factors other than salt intake, but enough to consider adding additional salt to the diet. Commented that it would be convincing evidence. 'Reducing sodium intake with less or no salt in the diet can have significant health benefits,' he said.
According to Anika Rosengren, a professor at the University of Yoteboli who did not participate in the study, salt cannot be completely removed from the diet, but there is an 'optimal amount', and the evidence for salt so far shows that it is a normal amount. If you are a healthy person who is taking salt, you do not have to worry about salt intake, and it is better to balance the salt intake by eating a diet that contains a lot of fruits and vegetables.
He also advises that people at high risk of heart disease should refrain from salt, and 'do not add extra salt to cooked foods' is one way to do this.
