A brand of dark soy sauce -- y&y brand -- that has 70% and 40% of your iron and vitamin C RDA?!
I was wondering why would a dark soy sauce have these nutrients in such abundance? Is it normal for any soy sauce to have vitamin C and iron when they're not listed in the ingredients? The ingredients on the bottle show water, extracts of soybeans, wheat flour, sugar and salt.
My question is, where could all of this iron and vitamin C be attributable to? Normally, what is in a "good quality" dark soy sauce? I don't want 70% of my iron in only 2 tsp (15 ml) soy sauce -- I use more than 2 tsp daily of soy sauce!
Thanks a bunch,
Av

Although soy beans are a good source of iron by themselves, the process of making soy sauce could drastically reduce the natural levels of iron & Vitamin C. Hence, the soy sauce could likely be fortified with iron & Vitamin C. Soy sauce is supposed to inhibit iron absorption in our diet and on the other hand Vitamin C improves iron absorption, this could explain the rationale for fortification, especially to combat nutritional deficiencies in the poorer parts of Asia.
