The Trader Joe's near where we live sells cashews with 50% less salt. Marvelous!
Salt doesn't just contain sodium and clorine, it is sodium and clorine (NaCl). Necessary for life, but too much can cause high blood pressure. One can learn to regulate one's taste and back off on foods that taste too salty--such as the cashews (and other nuts) in a can that the run-of-the-mill supermarkets sell. Same with processed sandwich meats, Read labels and use your taste buds.
By the way, at age 76, my blood pressure is 120/70.
