Actually going by the Gerson diet i think salt is probably Not an essential ingredient. Most people, not eating a strictly organic vegan diet, probably benefit from Sea Salt today because it contains minerals that are so depleted from their current diet. However, after being cured of cancer I don't know if the previous patients of Gerson continued to eliminate salt completely from their diet. And since they lived into their 70's there is no way to know whether eliminating salt completely from ones life is beneficial or hazardous. Though i would like to discover any research of this if anyone has learned otherwise.
