Well I have nothing better to do this morning so I thought I
would revisit Iron and UC,since I have not looked in a long time.
I will be adding studies as I find them.
Iron fortified flour started in the USA early 1940's.
You will notice today that just about any store bought processed food is fortified with iron and other
nutrients. Some of the iron is in the form of ferrous sulfate/fumerate,other may be
metallic reduced iron.
Iron is also a limiting nutrient for bacteria.
Are we getting toooo much iron from the diet.
Here is one to start off with,I never saw this one before but it is scary.
Here is a table from the gov.
Looks like adult females need 18 mg while males need 8.
I serving of 100% fortified cereal = 100% required non heme iron
for an adult female.
Looks like about 10% is absorbed.
What happens to the other 90% I think it goes into the colon,some could go into urine,not sure.
They made me hunt again,looks like the 90% goes out in the poo. So if it is in the poo
then the bacteria can get at it, and it can also cause oxidation.
So if you eat a lot of processed fortifed snack foods,you are getting a lot of iron. Natural foods not so much.
In the above water report there only talking about 0.1mg increase,
cant seem to find the absolute amount of iron in the water though.
But one bowl of fully fortified cereal is 18mg.
They made me hunt.It looks like the average is 0.3mg/liter from water,most iron intake is
from food. But this above study was only talking about 0.1mg increase.
Another of real interest,since this population is not eating a sad diet.
