This test determines the deuterium levels in meats, fish, vegetables, fruits, breads, soups, stews, and food ingredients like flour, butter, herbs, seasoning, etc. as well as in supplements and protein powders. The test will provide one value that represents how much deuterium is in the food after we remove the residual moisture and liquid from it. The test can be used to compare and evaluate everything from GMO vs. non GMO to organic vs. non organic to vegetables vs. fruits to local vs. imported to gluten vs. gluten-free and more. Research indicates that eating low deuterium foods may be the fastest and best way to increase your energy, slow the aging process and prevent and fight disease.
