Heme-iron intake / type 2 diabetes

A careful reading of the conclusions disproves the favorite theory of our posting friend,ie. that
iron causes diabetes and that blood letting reduces risk for it. The total amount of iron ingested
and iron from non-red meat made no difference, neither did blood letting. Ingesting red meat, which
also happens to contain iron as does other meats, has something about it that is related to an
increased risk. This kind of mistake happens when one is looking for one's farvorite theory to be
confirmed.

Dietary iron intake and blood donations in relation to risk of type 2 diabetes in men: a
prospective cohort study.

Brigham and Women's Hospital, Boston (JM, MJS, WCW, and FBH).

BACKGROUND: Excessive iron stores may promote insulin resistance and lead to the development of
type 2 diabetes. However, prospective data relating iron intake and blood donations (determinants
of body iron stores) to diabetes incidence are limited. OBJECTIVE: We examined iron intake and
blood donations in relation to the incidence of type 2 diabetes. DESIGN: We followed men aged 40-75
y who participated in the Health Professionals' Follow-up Study; were free of diabetes,
cardiovascular disease, and cancer in 1986; and provided dietary data (n = 38 394). Of those
participants, 33 541 also provided a history of blood donation during the past 30 y in 1992.
RESULTS: During 12 y of follow-up, we ascertained 1168 new cases of type 2 diabetes. After
adjustment for age, body mass index, and other diabetes risk factors, total iron intake was not
associated with the risk of type 2 diabetes. Intakes of total heme iron [multivariate relative risk
(RR) for extreme quintiles: 1.28; 95% CI: 1.02,
1.61; P for trend = 0.045] and of heme iron from red meat (RR: 1.63; 1.26,
2.10; P for trend < 0.001) were associated with an increased risk. However, heme-iron intake from
sources other than red meat was not associated with diabetes risk (RR: 0.99; 0.81, 1.22). No
significant associations were found between blood donation and the risk of type 2 diabetes.
CONCLUSIONS: Heme-iron intake from red meat sources is positively associated with the risk of
type 2 diabetes. Total iron intake, heme-iron intake from non-red meat sources, and blood
donations are not related to the risk of type 2 diabetes.

Not at all, what it shows is that in this specific research iron intake is not an independent
variable for diabetes risk. Recall, total iron or iron from non-red meat sources had no effect. Iron
and blood letting as an independent variable were not confirmed. Red meat did, and it also happens
to contain iron, as well as many other things. This drives a woodden stake through the heart of your
favorite notion. That which you thought it says in fact said the oppisite from what you wanted, nay
blindly, find it now really says.
