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. Sodium chloride also appears to have a negative effect on the human immune system, the study said.
"We examined volunteers who consumed six grams of salt in addition to their daily intake, this is roughly the amount contained in two fast-food meals, i.e. two burgers and two portions of French fries," Kurtz said. After one week, the scientists took blood from participants and examined the granulocytes. The immune cells coped much worse with bacteria after the test participants had started to eat a high-salt diet.
In human volunteers, excessive salt intake also resulted in increased glucocorticoid levels. The best-known glucocorticoid cortisone is traditionally used to suppress inflammation, according to the study. "Only through investigations in an entire organism were we able to uncover the complex control circuits that lead from salt intake to this immunodeficiency," Kurts stressed.
