PARIS, July 11 (Benin News) –
According to a study of more than 500,000 people and published in the “European Heart Journal”, people who salt their food more at the table are at a higher risk of dying prematurely, whatever the cause.
Compared to people who never or rarely added salt, those who always added salt had a 28% higher risk of premature death. In the general population, regarding three in 100 people between the ages of 40 and 69 die prematurely. The increased risk of always adding salt to food observed in the current study suggests that one more person in 100 might die prematurely in this age group.
Additionally, the study found a shorter life expectancy in people who always add salt than in those who never or rarely do so. At age 50, the life expectancy of women and men, respectively, who always added salt to their diets was reduced by 1.5 years and 2.28 years, compared to those who did not. never or rarely added any.
The researchers, led by Professor Lu Qi of Tulane University’s School of Public Health and Tropical Medicine in the US, say their findings have several implications for public health.
“To my knowledge, our study is the first to assess the relationship between the addition of salt to foods and premature death,” he says. It provides new evidence to support recommendations to change eating behaviors to improve health. Even a modest reduction in sodium intake, by adding less salt to foods or adding no salt to the table, is likely to produce substantial health benefits, especially when achieved in the population. general.
It’s notoriously difficult to gauge total sodium intake because many foods, especially precooked and processed foods, are heavily salted before they hit the table. Studies assessing salt intake by urinalysis often take only one urinalysis, and therefore do not necessarily reflect typical behavior. Also, foods high in salt are often accompanied by foods high in potassium, such as fruits and vegetables, which is good for us.
Potassium is known to protect once morest the risk of heart and metabolic diseases such as diabetes, while sodium increases the risk of diseases such as cancer, high blood pressure and stroke. For these reasons, the researchers decided to analyze whether or not people added salt to their food at the table, independent of the salt added during cooking.
“Adding salt to foods at the table is a common eating behavior that is directly related to an individual’s long-term preference for salty-tasting foods and their habitual salt intake,” Qi points out. In the Western diet, the addition of salt at the table accounts for 6-20% of total salt intake and is a unique way to assess the association between usual sodium intake and risk of death.
The researchers analyzed data from 501,379 people who took part in the UK Biobank study. When they joined the study between 2006 and 2010, participants were asked, through a touchscreen questionnaire, whether they added salt to their food never/rarely, sometimes, usually, always , or if they preferred not to answer.
The researchers adjusted their analyzes to take into account factors that might affect the results, such as age, gender, race, deprivation, body mass index (BMI), smoking, consumption of alcohol, physical activity, diet, and medical conditions such as diabetes, cancer, and heart and vascular disease. Participants were followed for an average of nine years. Premature death was defined as death before age 75.
In addition to finding that always adding salt to food was associated with an increased risk of premature death from all causes and reduced life expectancy, the researchers found that these risks tended to be slightly reduced in people who consumed the highest amounts of fruits and vegetables, although these results were not statistically significant.
“This result did not surprise us, as fruits and vegetables are important sources of potassium, which has protective effects and is associated with a lower risk of premature death,” says Professor Qi. As our study is the first to report an association between the addition of salt to foods and mortality, further studies are needed to validate the results before any recommendations can be made.
Professor Qi and his colleagues will conduct further studies on the relationship between the addition of salt to foods and various chronic diseases, such as cardiovascular disease and diabetes. They also hope to conduct possible clinical trials to test the effects of reducing added salt on health outcomes.
