Iron Intake and the Risk of Type 2 Diabetes in Women: A prospective
cohort study.
Rajpathak S, Ma J, Manson J, Willett WC, Hu FB
Diabetes Care. 2006 Jun ; 29(6): 1370-1376

OBJECTIVE: Epidemiological studies suggest that high body iron stores
are associated with insulin resistance and type 2 diabetes. The aim of
this study was to evaluate the association between dietary intake of
iron and the risk of type 2 diabetes. RESEARCH DESIGN AND METHODS: We
conducted a prospective cohort study within the Nurses' Health Study.
We followed 85,031 healthy women aged 34-59 years from 1980 to 2000.
Dietary data were collected every 4 years, and data on medical history
and lifestyle factors were updated biennially. RESULTS: During the 20
years of follow-up, we documented 4,599 incident cases of type 2
diabetes. We found no association between total, dietary, supplemental,
or nonheme iron and the risk of type 2 diabetes. However, heme iron
intake (derived from animal products) was positively associated with
risk; relative risks (RRs) across increasing quintiles of cumulative
intake were 1.00, 1.08 (95% CI 0.97-1.19), 1.20 (1.09-1.33), 1.27
(1.14-1.41), and 1.28 (1.14-1.45) (P(trend) /=2.25 mg/day and those
with intake <0.75 mg/day was 1.52 (1.22-1.8 Cool

. The association between
heme iron and the risk of diabetes was significant in both overweight
and lean women. CONCLUSIONS: This large cohort study suggests that
higher heme iron intake is associated with a significantly increased
risk of type 2 diabetes.

Ah, what wonders editing of the full abstract invents. Here is the first
observation from the full abstract:

"We found no association between total, dietary, supplemental, or nonheme
iron and the^ risk of type 2 diabetes. However, heme iron intake (derived^
from animal products) was positively associated with risk ..."

The questions we ask determine the answers we get. In other studies,
asking about differences in meat sources found that non red meats were not
associated with higher diabetes risk and confirms that total iron isn't
either. Other research finds that red meat and processed meats,ie. deli
type products, have the risk with diabetes. Thus it is not meat but some
factor in some meats that is the risk factor, prhaps the saturated fats
which also have a higher risk level for diabetes.

Tom,

I have been ethical vegetarian all my life (That is full 52 yrs). I
still got diabetes. So while I have no way to comment on whether or not
eating meat makes you more susceptible to getting T2 diabetes, I know
for fact not eating meat is no free pass either. I have both sides of
my family members who got diabetes by the time they were between 40 and
50. They are all vegetarian. Many died by age 75 due to heart attack.

What is common for all is a lifestyle that had very little physical
activity between age 20 and 40 and not enough whole foods and greens in
thier diet.

Since dxed I have become vegan. But more importantly I have devoted at
least 1 hr in daily exercise and have been eating plenty of plant based
whole foods. And yes my numbers are reasonably good (A1c between
5.2-5.4).

But I can not honestly say becoming vegan has any thing to do with it.
I think lions share in my control on numbers is the fact that I do take
Metformin and have been eating a lot less calories and I am also being
order of magnitude more physically active.

Note that it does not take much efforts to bring in control for first 5
yrs after being dxed. Its when you have 10+ yrs of good control one can
reasonably claim what may be definitively working for him/her. So far I
have not discovered any magic bullet. The advice of eating lot less
calories derived from fiber rich food and having at least 1 hr of
physical activity every day seems to work in most cases. At least that
is how far my research has taken me

So beating up meat eater may make you feel you are just spreading the
message, you may need to at least understand the limitations of your
message. BTW it will also help if you talk in complete sentences and
use a language that is more representative of your faith.

From the abstract:

"We found no association between total, dietary, supplemental, or nonheme
iron and the risk of type 2 diabetes."
<*** End of File ***>

Total or supplemented iron had no risk. Iron from animal products had a
risk. Asking the additional question, is it all animal products? Other
research found that only red and processed meats, not other animal sources
have the risk. So it is not animal iron alone that is the risk and
strongly suggests that something about red and processed meats in addition
to or not associated with iron is the source of the risk. That is the way
science works, it asks questions in a variety of ways about a topic to
tease out the real associations between factors. Almost always when we
ask only one question we get distorted results. Taking all the research
to account, total or supplemented or non red/processed meat is not a risk
factor for diabetes.
