Anyone see something .. odd .. ?

the proportion of American Indian/Alaska females with anemia was 31
percent, compared to 26 percent of Asian/Pacific Islander females.

"Is your husband a Native ...?" .. he asks ..
"No .. why do you ask .. " .. the mother inquires.
"Because he has such a nice high iron level .. we thought he was native

'Surprising' findings reported about iron overload
Asians, Pacific Islanders have highest blood iron levels
BIRMINGHAM, Ala. - UAB and international scientists studying
iron-overload disorders have made the unexpected discovery that Asians
and Pacific Islanders have the highest levels of iron in their blood of
all racial/ethnic groups who were screened.
Just found to be the HIGHEST IN THE FRIGGIN WORLD FOR IRON LEVELS /
stores ..
And THEY are .. 31% .. iron DEFICIENT .. according to these ..
researchers ..?
Researchers .. ?
The whooooooollllle .. iron fortification program of our foods are
BASED on this .. information above.
ALL of it ..
Hmmmmmm..
That would make me .. right ..

For nonpregnant American Indian/Alaska Native, Asian/Pacific Islander,
Hispanic, and non-Hispanic females aged 12 to 49 years, iron deficiency data
were statistically unreliable or not collected in 1988-1994.

The following study shows clearly .. due to previous studies which left

the requirement for absorbed iron was estimated to be 1.46 mg/d for

Inevitable iron loss by human adolescents, with calculations of the
requirement for absorbed iron.

[Medline record in process]
In growing individuals, the requirement for absorbed iron consists of
iron needed for growth and iron needed to replace inevitable iron loss.
We were able to estimate inevitable iron loss by adolescents because
total body iron of the adolescents had been enriched with the stable
isotope, (58)Fe, as the result of earlier studies of iron absorption.
During an interval beginning at least 1.56 y after isotope
administration (a time sufficient for complete mixing of the isotope
with total body iron) and extending for no less than 3.29 y, we
determined the isotopic enrichment of circulating iron. On the basis of
several assumptions, we calculated total body (58)Fe and total body
iron at the beginning and end of the interval. Because of complete
mixing of the isotope with total body iron, fractional total (58)Fe
loss was the same as fractional loss of total iron. In males, the
fractional loss of iron was 9.70%/y and the quantitative loss was 256
mg/y or 0.70 mg/d. In females, the fractional loss of iron was 14.60%/y
and the quantitative loss was 306 mg/y or 0.84 mg/d. Using several
assumptions, we then calculated that the iron requirement for growth
during this interval was 0.76 mg/d for males and 0.31 mg/d for females.
Adding the iron loss to the iron requirement for growth, the
requirement for absorbed iron was estimated to be 1.46 mg/d for males
and 1.15 mg/d for females.

Nursing questions and discussion

This intake in an adolescent .. 1.46 mg/d for males and 1.15 mg/d for
females .. would be considered to be ? .. in relation to THESE ..
markers .. ?
10 ppm iron (iron restricted) or 200 ppm iron (standard/high
iron)
Would if one were to go by the NOW shown DECREASE in .. NEEDED iron ..
bring the adolescents DOWN into the degree of iron restriction required
to .. prevent / impede hookworm infection .. ?

Dietary iron content mediates hookworm pathogenesis in vivo.

Hookworm infection is associated with growth delay and iron deficiency
anemia in developing countries. A series of experiments were designed
in order to test the hypothesis that host dietary iron restriction
mediates susceptibility to hookworm infection using the hamster model
of Ancylostoma ceylanicum. Animals were maintained on diets containing
either 10 ppm iron (iron restricted) or 200 ppm iron (standard/high
iron), followed by infection with A. ceylanicum third-stage larvae.
Infected animals fed the standard diet exhibited statistically
significant growth delay and reduced blood hemoglobin levels compared
to uninfected controls on day 20 postinfection. In contrast, no
statistically significant differences in weight or hemoglobin
concentration were observed between infected and uninfected animals fed
the iron-restricted diet. Moreover, iron-restricted animals were
observed to have reduced intestinal worm burdens on day 10 and day 20
postinfection compared to those of animals maintained on the
standard/high-iron diet. In a subsequent study, animals equilibrated on
diets containing a range of iron levels (10 ppm, 40 ppm, 100 ppm, or
200 ppm) were infected with A. ceylanicum and followed for evidence of
hookworm disease. Infected animals from the intermediate-dietary iron
(40- and 100-ppm) groups exhibited greater weight loss and anemia than
those in the low (10-ppm)- or high (200-ppm)-iron diet groups.
Mortality was also significantly higher in the
intermediate-dietary-iron groups. These data suggest that severe
dietary iron restriction impairs hookworm development in vivo but that
moderate iron restriction enhances host susceptibility to severe
disease.
