A new study conducted by researchers at Children's Hospital Oakland
Research Institute (CHORI), in close collaboration with scientists at
the National Institute of Perinatology in Mexico, is the first to show
that the current iron supplement recommendation for pregnant women who
are not anemic is too high and could lead to birth complications for
infants such as premature birth and low birth weight. This new research
conflicts with recommendations from the World Health Organization (WHO)
and the Centers for Disease Control (CDC). It is hoped that the results
of this study will lead to new recommendations from both organizations.
The study, featured in the May issue of Archives of Medical Research,
suggests that pregnant women who are not anemic should take iron
supplements weekly rather than daily. Women who are anemic have low
levels of healthy red blood cells and need higher doses of iron
supplementation. The study shows that pregnant women who are not anemic
and follow the recommended daily dosage can suffer from iron overload
and are more likely to experience birth complications.
Iron deficiency is common among women of childbearing age.
Consequently, doctors have ordered daily supplements of 60 to 120 mg of
iron to prevent or correct anemia and iron deficiency during pregnancy.
"What happens is that excess iron in pregnancy can drive the hemoglobin
levels above desirable levels, so that by the end of the second
trimester of pregnancy, 27 percent of the non-anemic women in our study
had hemoglobin levels that were undesirably high," said Fernando
Viteri, MD, Scientist at Children's Hospital Oakland Research Institute
(CHORI). "In these women, the risk of delivering premature babies or
newborns with low birth weight quadrupled."
In contrast, only 7 percent of the women on weekly supplements
developed high hemoglobin levels. The reason for the weekly dose - and
in far smaller amounts - is biological and corresponds with the
turnover of the intestinal lining, which renews itself every five to
six days. The fresh cells are programmed to absorb iron according to
the person's iron reserves and needs. The cells absorb more if reserves
are depleted and less if they are adequate. Dr. Viteri's research
concludes that iron supplementation is still beneficial, but must be
regulated based on whether a woman is anemic.

| This is a good article. It clearly illustrates the idea of the minimal,
optimal and maximal in biological process. The min to get an effect, the
opt to get the best results, and the max where adding more doesn't help
and can become self defeating. So in this case the optimal supplement
level was adjusted.
"Healthy" is the important term. Low iron is the world's number one
health problem because so many mothers start out low and get lower as
pregnancy advances which leads to health problems for the children. In
those cases the min opt and max are at different levels and a great deal
of research is being done to define them and help get supplemental iron
into the diet.

No actually the important .. PHRASE .. is .. "Iron Intake Advice Too
High"
THAT is WHY the study was conducted ..
You .. for some reason .. seem to think you are NOW .. 'up' .. on this
... subject .. ?
It seems they go .. CONTRARY .. to WHO organizations' ..
recommendations ..
This is .. astounding ...VERY .. recent ..
I wonder if .. YOU .. have ever mentioned it .. before .. ?
Did you .. attempt to .. warn .. anyone .. ?
A quick search of .. "pussies and iron warning" .. doesn't bring up a
... single .. post by .. YOU ..
I guess you must have .. missed .. that .. one ..
Miss anything else .. ?
Like some .. cojones .. ?
Heh .. heh ..
