Low-sodium alternatives for Asian cooking sauces? I love Asian cooking, but my doctor wants me on a low-sodium diet. Unfortunately, even the "lower-sodium" or "reduced sodium" versions of sauces (soy, tamari, etc.) are extremely high in sodium. Is there any alternative that can replicate the flavor of these sauces without the heavy dose of sodium?
Unfortunately, the sodium chloride salt is a requirement for the fungus and brewing process which goes into making soy sauce. You are extremely unlikely to find a much lower-salt soy sauce; however, experiment with vietnamese cuisine which uses more chili and less soy.

If you can tolerate some sodium, this is the lowest sodium soy sauce I can find: Kikkoman less salt soy sauce. It has 3.4g sodium per 100ml, which gives 170mg per 5ml tsp, around 6% per tsp or 18% per 15ml tablespoon. (These percentages are based on the US and UK sodium recommendation of 2400mg per day, or 6000mg of salt.)
