London: Researchers have found that eating too much salty diet weakens your immune system and makes it harder for your body to fight off bacterial infections.

For the findings, published in the journal Science Translational Medicine, the research team fed mice a high-salt diet and found more severe bacterial infections.

Human volunteers who consumed an additional six grams of salt per day also showed pronounced immune deficiencies. This amount corresponds to the salt content of two fast-food meals, the study said. Five grams a day, no more: This is the maximum amount of salt that adults should consume according to the recommendations of the World Health Organisation (WHO). It corresponds approximately to one level teaspoon. "We have now been able to prove for the first time that excessive salt intake also significantly weakens an important arm of the immune system," said study researcher Christian Kurts from the University of Bonn in Germany.

According to the researchers, this finding is unexpected, as some studies point in the opposite direction. "We were able to show this in mice with a listeria infection," said study lead author Katarzyna Jobin from the University of Wurzburg.

"We had previously put some of them on a high-salt diet. In the spleen and liver of these animals, we counted 100 to 1,000 times the number of disease-causing pathogens," Jobin added.

Listeria is bacteria that are found for instance in contaminated food and can cause fever, vomiting and sepsis. Urinary tract infections also healed much more slowly in laboratory mice fed a high-salt diet.
