Scientists have also discovered a dangerous effect of high salt intake

Consuming too much salt can cause us heart problems, a fact that is already known to everyone. But a new study has established another side effect that is of concern, especially in the current epidemiological context. New research has found that the level of salt we consume can make us more vulnerable to disease caused by bacteria. So salt can also affect immunity.

The study , published in the journal Circulation, complements some research from 2015, which found that a large amount of salt reaching the blood affects how a certain type of white blood cell reacts when it detects an unhealthy cell. But then scientists “still didn’t know what was going on in the cells,” said Dr. Sabrina Geisberger of the Berlin Institute for Medical Systems Biology (BIMSB).

In the latest study, the team examined “the metabolism of immune cells that have been exposed to high concentrations of salt ,  according to a statement. This time, they observed how salt influences immunity by disrupting the respiratory chain, which causes cells to produce less ATP (adenosine triphosphate) and less oxygen. ATP is a “universal fuel that powers all cells” , providing energy for muscle and metabolic regulation.

Professor Markus Kleinewietfeld of Hasselt University said: “Of course, the first thing you think about is cardiovascular risk. But several studies have shown that salt can affect immune cells in a variety of ways. If such an important cellular mechanism is disrupted for a long time, it could have a negative impact and lead to inflammatory diseases of the blood vessels or joints, or to autoimmune diseases. “

According to this study, nutrition experts recommend that adults limit their daily intake to a maximum of five or six grams of salt, taking into account the “hidden” in processed foods.
