Excess dietary salt weakens immunity against bacteria in kidneys, say researchers: Health : Nigerialog.com - Nigeria's Premier Online Forum
Similarly, excess dietary salt made kidney infections with E. coli worse. The researchers traced this impaired ability to fight off bacterial infections to immune cells called neutrophils, which ingest bacteria. They believe that the kidneys’ response to high dietary salt may indirectly affect the neutrophils.The kidneys use a molecular mechanism for detecting excess sodium in the bloodstream and excreting it in the urine. But in the process, this mechanism raises levels of steroid hormones called glucocorticoids, as well as a waste product called urea. Both glucocorticoids and urea inhibit the ability of neutrophils to kill bacteria.
