Serum Iron Levels are Linked to the Metabolic Syndrome
Body iron levels have been found to be correlated with another of our
diseases of civilization - the metabolic syndrome. The higher the iron
level, the more likely the risk of metabolic syndrome . . .
Robert W. Griffith, MD
Introduction
People who have hemochromatosis - an inherited disease in which there's
an overload of iron in the body - often develop type 2 diabetes. And a
study found that, indeed, increased heme-iron intake from red meat was
clearly associated with an increased risk of diabetes (see the first
link below). Although that study couldn't directly relate overall iron
in the diet with a risk of diabetes, the suspicion was there. Now a
study has examined if increased levels of iron in the blood are linked
to the occurrence of the metabolic syndrome, one common feature of
which is a raised fasting blood sugar level (i.e. pre-diabetes). The
investigators from Johns Hopkins university have published their
findings inDiabetes Care, and we summarize their report here.
What was done
The scientists used data from the Third National Health and Nutrition
Examination Survey (NHANES III) gathered between 1988 and 1994. This
involved a nation-wide survey sample with a home interview and a
detailed clinical examination. They limited their analysis of results
from healthy NHANES III participants aged 20 or older who weren't
pregnant or nursing.
The metabolic syndrome was defined as the presence of at least 3 of the
following:
Abdominal obesity - waist circumference greater than 102 cm (40 inches)
in men, or 88 cm (35 inches) in women
Blood triglyceride level 150 mg/dL or above (1.7 mmol/L or above)
HDL-cholesterol 40 mg/dL (1.04 mmol/L) or below in men, or 50 mg/dL
(1.29 mmol/L) or below in women.
High blood pressure - 130/85 mm Hg or higher, or taking blood pressure
medication
High fasting glucose level - 110 mg/dL (6.1 mmol/L) or above
(If you want to see if you may have the metabolic syndrome, go to the
second link below.)
Serum ferritin levels1were measured in all participants. Ferritin
quartiles - equal-sized groups of participants based on their ferritin
levels (low, low-mid, high-mid, and high) - were formed for three
separate classes of subjects: premenopausal women, post-menopausal
women, and men. (Women who are menstruating have lower iron stores,
naturally.)
Tests were also done to search for possible insulin resistance and the
presence of undiagnosed hemochromatosis.
What was found
First, the investigators excluded people with likely hemochromatosis
from further analyses. This left 6,000 subjects in the final sample.
The average ferritin levels in pre-menopausal women, post-menopausal
women, and men were: 33.6, 93.4, and 139.9 microgram/liter,
respectively.
The metabolic syndrome was more common in the high ferritin quartile
compared with the low ferritin quartile, for men and both classes of
women. For instance, the rates of metabolic syndrome in men with the
highest and lowest ferritin levels were 27% and14%, respectively. In
premenopausal women these rates were 15% and 6%, respectively.
Individual components of the metabolic syndrome also correlated with
the serum ferritin levels - especially raised triglyceride and raised
fasting glucose levels.
Insulin resistance was also increased, corresponding to the ferritin
quartiles low, low-mid, high-mid, and high. Adjusting for age, smoking,
alcohol intake, and BMI made no difference to these findings.
What this means
Body iron stores are clearly linked with the occurrence of the
metabolic syndrome and, as the earlier study cited, with the
development of type 2 diabetes. It's likely that the chief effect of
raised iron levels is connected with impaired insulin resistance, with
the other findings following on from this. But is this connection one
of cause-and-effect, or are ferritin levels just a 'marker' of insulin
resistance?
This question is obviously one that needs answering if the cause of
type 2 diabetes is to be unraveled. More research is necessary, as we
always seem to say. However, there is a take-home message: try not to
let your iron levels get too high by eating less red meat (which seems
to be a relevant source of heme-iron), and try to eat more veggies, for
hundreds of good reasons. Of course, don't lose sight of the fact that
some elderly people just don't get enough iron in their diet. If you
aren't sure, ask your doctor about a serum iron test.

| No cigar, metabolic syndrome leads to only a part of the people having it
lead to diabetes. Iron doesn't cause diabetes and the world's highest
rate of it and for metabolic syndrome is found in places where little or
no animal products are eaten. Another counter example to the iron causes
all diseases because people eat meat idea.

| The study is about .. metabolic syndrome ..
[vbcol=seagreen]
metabolic syndrome <<
You disagree with the .. above .. ?
No .. ?
Then what are you doing on this .. thread .. ?
Oh yeah .. you are again attempting to .. discredit .. work ..
You are .. again .. attempting to divert .. attention .. away from
medical studies ..
What next .. ?
Can't think of a lie .. ? .. or can't place a few scrambled medical
studies .. cut and pasted to fit your own little .. agenda .. ?
Eh ..
WHAT .. a .. pussy ..
Heh .. heh ..

| We want people not to be confused that your "work",ie. obsession, has any
foundation in fact about which they should concern themselves overly and
that the iron causes all disease because people eat meat idea is a dud
from the get go.

| Show me where any of the examples I provided did not say that red meat is
a risk factor for diabetes. This was the request you made and was
provided. Your idea is a now disproven dud, it only takesone counter
example to the iron causes all disease because people eat meat idea to
toss it. We have provided several and it is history and you can't bring
it back from its well deserved grave. We want people to see this again
and again so there is no possible chance they will be confused by your
obsessive claims and tactics.

<<
You said .. ONLY .. red meat and NOT .. total heme iron ..
That is WHY you included .. portions .. of the studies .. NOT ..
including the portions .. selectively .. which did say .. total heme
iron .. associated ..
Now THAT .. is doctoring ..
That is .. medical research malpractice ..
Withholding relevant information in a medical newsgroup .. in a medical
newsgroup in which there are open festering diabetic .. wounds ..
people begging their doctors to let them keep their .. limbs ..
And .. there .. YOU .. are ..
Caught .. in the open ..
Now .. read my lips ..

| No, you asked a specific question and it was answered specifically. Each
study made several points and only the point related to your question was
mentioned. I also think you are mixing me up with another poster, not
uncommon confusion on your part. The iron causes all disease because
people eat meat idea idea is now a dead ded because several counter
examples have been shown where only one is required. This whol hissy sint
is to avoid that dead dog now buried.

| Listen up .. you twobitlying piece of sht ..
You HAVE .. all along .. SPECIFICALLY stated .. "red meat ONLY is
associated with diabetes .. " ..
You've said it a number of times ..
You deny .. NOW .. saying .. specifically .. ONLY red meat associated
with diabetes .. ?
Is that what you are saying .. ?
If you don't think I can dredge up your bullsht .. try me ..
So like I said .. and like we both .. KNOW ..
You are a lying two bit piece of sht ..
Who loves ya.

Yup, a large population study had that conclusion, nothing denied.
The iron causes all disease because people eat meat as a punishment by God
as revealed in a secrete bible code requires only one counter example to
toss it. It be tossed.

Nope, with inflation a threebitlying.on Low iron causes mental problems,
such as confusion and lack of attention. I have said red meat is a risk
factor, but never the only risk factor. Single causes are your ball game.
The idea iron causes all disease because people eat meat, as a punishment

You've said it .. how many times .. ?
And NOW you deny it ..
It is the ONLY argument you've used ..
And NOW ..
Whining .. like I said .. like a little whining little btch ..
http://tinyurl.com/dovgl
1 total iron not related to risk of diabetes
2 risk not related to fish and poultry iron sources
Now .. waffle .. lie .. some more ..
You and I .. both .. KNOW .. don't we .. ..
You are nothing but a fkduplittlelyingtwobitpceof.. sht ..
And since both you and I .. KNOW ..
THAT .. is .. after all .. all that .. REALLY .. matters .. isn't it ..
That it is .. agreed .. that you are .. nothing but ..a

Heh .. heh ..
All we can hope for now .. is .. you don't get a chance to .. breed ..

among others. In a large population study total iron was shown not to be
a risk factor for diabetes. Red meat is a risk factor for diabetes.
