In his best selling book, "Grain Brain," Dr. David Perlmutter notes that many brands of soy sauce contain wheat. On page 225 of the hard cover edition he says, "Note: Although some naturally brewed soy sauces are technically gluten-free, many commerical brands have trace amounts of gluten." He goes on to recommend using tamari soy sauce as a gluten free alternative.

Joyce Chen's Gluten Free Soy Sauce is a more geniune replacement for gluten containing soy sauce. It contains less sodium than other brands on the market. It's certified Kosher, and contains no added chemicals, no added MSG, no artificial coloring, and no preservatives. And, it's delicious!
