There's a free kindle book today called Simply Raw in which the author claims the above. Well, she didn't say specifically kosher or sea salt, just "white salt." She says the white stuff is over-processed and the minerals stripped. I don't find that hard to believe about what is commonly known as "table salt" but surely this is not the case with kosher or sea salt. She goes on to say that the two salts she recommends contain 89 or so minerals and is actually good for you and won't cause health problems. I thought as far as health issues are concerned, salt is salt is salt. Any nutritionists on board who can shed light on this?
