Hi All, My name is Laura and I have been lurking on this list since my sister loaned me the book Neanderthin. Currently I am reading "Nutrition and Physical Degeneration" by Weston Price DDS, an interesting book. The sea salt that I have been using is "RealSalt." It is from Utah, USA and is available in health food stores. The package states the following: +++++++++++++++++++++++++++++++++++++++ "All salts are not created equal! Did you know there is a vast difference in the quality and content of table salts on the market today" Some have had chemicals added to them as anti-caking agents. Some have been heated or cooked to drive off moisture. Some have had valuable natural minerals removed in processing. Are these differences in salt significant to us as consumers? Yes! Some research indicates that even more important than the quantity of salt you eat, may be the type of salty you eat. Because we care about how your food tastes and your good health, we have chosen to offer you RealSalt, the Natural Mineral Sea Salt. It has no chemicals added to it that might change its delicate "sweet-salt" flavor. It has not been heated or "cooked" in processing. It contains numerous trace minerals known to be valuable in human nutrition. The Minerals in RealSalt RealSalt comes from an underground natural mineral rock salt deposit. Millions of years ago, near what is now known as the town of Redmond, Utah, there existed a supersaturated body of seawater. It congealed to form a great vein of rock salt and captured within the crystallization over thirty wholesome trace minerals. Since it is an all natural product, the analysis and color will vary. Below is a summary of analyses taken over the past several years. Some clumping will occur due to the absence of chemicals. Sodium Chloride 98.32% Calcium .40% Potassium .12% Sulphur .11% Magnesium .10% Iron .06% Phosphorus .05% Iodine .002% Manganese .0015% Copper .001% Zinc .0006% RealSalt also contains numerous other trace minerals in minute quantities. ++++++++++++++++++++++++++++++++ Because this salt is from the ancient sea, it is free of the human caused pollutants that are currently in the ocean. The salt is marketed by Redmond Minerals Inc, Redmond, UT 84652, 800-367-7258. Best Regards, Laura Over 450 Photos of Chickasaw National Recreation Area http://chickasaw.homestead.com.
