| This pretty much shows the consumption of meat .. leads to
erythropoiesis .. erythrocytosis .. pseudo-polycythemia .. increased
blood cell mass ..
Which .. IMHO .. would give credence to the hypothesis .. the highly
absorbable form of iron / heme iron .. leads to .. polycythemia ..
increased red blood cell production .. ?
Logic .. ?

OBJECTIVE: To test the hypothesis that older men who consumed a
vegetarian (lacto-ovo) diet would develop a lower iron status compared
with older men who consumed a beef-containing diet during a period of
resistive training (RT). DESIGN: Experimental, repeated measures study.
SUBJECTS: Twenty-one healthy men aged 59 to 78 years, with a BMI range
of 24 to 33 kg/m(2), completed the study. INTERVENTION: All men
consumed a vegetarian diet for 2 weeks (baseline). After this, the men
were randomly assigned to one of two dietary groups. Eleven men
consumed a beef-containing diet, and 10 men continued to consume a
vegetarian diet for 12 weeks. During this time all subjects
participated in RT three days per week, designated as RT1 to RT12. MAIN
OUTCOME MEASURES: Serum ferritin and serum iron concentrations,
transferrin saturation, transferrin receptor, total iron binding
capacity, and selected hematological variables, as well as selected
nutrient intakes and estimated iron bioavailability from three-day diet
records, were determined at baseline, RT5, and RT12. STATISTICAL
ANALYSES: A general linear model repeated-measures ANOVA was used to
examine the effects of group, time, and group x time interactions for
iron status and dietary data. RESULTS: Total iron intake was not
different between the two groups; however, the beef group had a three
to four times greater intake of bioavailable iron (P<.01) than the
vegetarian group. Serum iron, total iron binding capacity, transferrin
saturation, and transferrin receptor were not significantly different
between the beef and vegetarian groups, or changed over time with RT.
Serum ferritin decreased over time in both the beef and vegetarian
groups during RT (P<.01). Re-introduction of beef into the diets of the
beef group increased hemoglobin concentration and hematocrit compared
with the vegetarian group during the 12 weeks of RT (group x time,
P<.05). These changes were within clinically normal limits.
APPLICATIONS/CONCLUSIONS: Older men who consume a beef-containing,
higher-bioavailable-iron diet, compared with a vegetarian,
lower-bioavailable-iron diet, have an increased hematological profile
during a 12-week period of RT. Older men who consume either a
beef-containing or a vegetarian diet maintain a hematological profile
within clinically normal limits during 12 weeks of RT.
