I’m a numbers person so let’s clear up this salt thing: how much do we really need in a day. The current RDA is 2300 mg or 2.3 g of salt. The 3mg that @widebody mentioned would be fatal and I believe they meant 3g.
According to Dr. James DiNicolantonio, author of “The Salt Fix,” We should be going after 3.5g to 4.5g (3500mg to 4500mg) per day for normal health.
I also learned from him that one of the best salts is Redmond’s Real Salt which is from ancient salt deposits and contain ample other minerals, like magnesium, that will give you a well balanced micro-nutrient level.
