how much sodium is in soy sauce
Kikkoman regular soy sauce has 920 mg. of sodium for just one tablespoon. Its lite or reduced sodium version has 575 mg. per tablespoon. Better but definitely not great. San-J Tamari has similar numbers: the regular is 960 mg. for one tablespoon while the reduced sodium version has 700 mg. per tablespoon.
Lately I've been ordering bottles of House of Tsang Lower Sodium Soy Sauce from Healthy Heart Market. This soy sauce has 320 mg. sodium per tablespoon, a slight improvement over the Angostura brand. Heart Wise Foods sells a super low sodium soy sauce, Chinatown brand. It has only 145 mg. per tablespoon.
