I have two brands of soy sauce at home. They come in about one half
gallon containers. One brand said a tablespoon provided 40% of your
daily requirement for v-C, and 4% of iron. The other brand provided
only 6% of iron. I checked the internet at diet facts, and they said
soy sauce provides zilch. Where do the producers come up with this
information.Do they test it themselves or farm it out to experts. Or
do they just put something on there believing they will never be
double checked.

A lot of nutritional information is garbage. Far and away
the most common error is listing fewer calories and/or fat
than is in the product.

As for soy sauce, you are not going to get any significant iron
or vitamin C from it. A more interesting question is whether
the amino acids in it are significant in your nutrition.
Some people believe hydrolyzed protein is metabolically useful,
even in what seems trvial amounts. Nobody really knows.

Could be either way, possibly depending on country of origin, I'd
think. I hope you were just looking at that info idly, rather than
with serious intent. 'Cuz if the nutritional analysis of soy sauce is
important to your diet you're already in big big
trouble.....<;-) -aem

There are two ways to do it. One is to actually test the product, but
that is expensive. The most common way is to use the ingredients at
their specific amounts and determine calories and nutrition from that.
If I says 6% iron, I'm sure it is in there..possibly from a
perservative. dkw
