<<Disclaimer: Verify this information before applying it to your situation.>> Supposedly a magnesium deficiency may cause sugar cravings. It would not be surprising that celiacs with malabsorption problems would be deficient in mg. Some forms of Mg can act like a laxative (epsom salts, for instance). If you choose to supplement Mg, watch out for a laxative effect and switch forms if you are bothered. Most Cal/Mag vitamins have a 2:1 calcium/magnesium ratio. If you're trying to add mg, you might need to go up to a 1:1 ratio. Foods high in Mg include: soybeans, wheat germ (not for celiacs), cashews, almonds. brazil nuts, baked beans, peanuts, molasses, and dark green leafy vegetables. Jean Jasinski ([log in to unmask])
