Jesus: "You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot."
Obviously Jesus is using salt as a figure of speech here, but there is something unnerving even prophetic about this passage because today, especially in the U.S., almost everyone is loading themselves with a highly refined and chemically toxic salt. The type of salt our bodies thrive on is unrefined sea salt which has anywhere between 60 to 80 trace minerals (most of the periodic table of elements). Many people have written about the benefits of sea salt, e.g.: http://drsircus.com/medicine/salt/real-salt-celtic-salt-and-himalayan-salt
So all I will hint at is that we are mineral deficient or unbalanced. Sodium and chlorine is used by the entire body. We needs loads of HCL to digest food and sodium to trigger the heart and brain. Sea Salt provides the properly balanced objects used in vital processes. Not using unrefined sea salt can help lead to mental illness and all sorts of diseases (such as thyroid and metabolic) which are rampant in the U.S. The U.S. economy thrives on mental illness and all sorts of diseases which are triggered by malnutrition by such practices as using refined, bleached, caked and raped salt. And there are other practices which are even more devious, irrational and harmful. The food situation in the U.S. is beyond critical. WE ARE FOOLS. The people of the U.S. have been swindled big time and nobody cares.
Anyway, salt is not just a seasoning, it is important that those who do not live by the Sea, who do not regularly consume Sea Food, get unrefined Sea Salt into their diets.
One can buy and use Himalayan, Celtic, or Real Salt
