Here’s another reason for you to put down that salt shaker.  Immunologists at the Technical University of Munich report that higher concentrations of sodium chloride, better known as table salt, turbocharges T cells increasing their production of the inflammatory mediators interleukin-4 and interleukin-13 and helping them go rogue.

Such rogue T-cells are at the heart of atopic dermatitis, a common allergy-mediated skin condition.  It turns out that atopic dermatitis is also associated with a 30 fold higher concentration of skin salt compared with that in normal skin.  The extra salt turns out to be doubly unhealthy as it not only triggers T-cell overactivity but also growth of that nasty bacterium Staph aureus.

There is plenty of natural salt in the food we eat so don’t pile on more.  If you want more flavor, use seasonings and spices that won’t throw your bodies machinery out of whack.
