Study confirms heart benefits of whole grains

(excerpt)

NEW YORK (Reuters Health) - Americans should bulk up on whole grains
like oatmeal, barley and brown rice to help lower their risk of
clogged arteries, heart attacks and strokes, according to
researchers.

In a review of seven major studies, the researchers found that higher
whole grain intake was consistently linked to a lower risk of heart
disease and stroke. On average, adults who ate 2.5 servings of whole
grains per day were nearly one-quarter less likely to develop
cardiovascular disease than their peers who rarely consumed whole
grains.

Whole grains are believed to benefit the heart in a number of ways.
The fiber and other nutrients in whole grains may help lower
cholesterol, blood sugar and insulin levels, as well as improve blood
vessel functioning and reduce inflammation in the circulatory system.

Yet surveys show that few Americans get the recommended three servings
of whole grains per day, according to the authors of the new study.
More than 40 percent of U.S. adults say they eat no whole grains.

"Many consumers and health professionals are unaware of the health
benefits of whole grains," lead study author Dr. Philip B. Mellen, of
Wake Forest University in Winston-Salem, North Carolina, said in a
statement.

Some may also be confused about what exactly constitutes a whole
grain. Whole grains contain three components: bran and germ, which are
rich in fiber and nutrients, and an endosperm, which contains starch
and protein. Highly processed grains, like white bread or snack foods
made from white flour, are stripped of the bran and germ.

In contrast, whole grains -- such as oats, barley, whole wheat, brown
rice and quinoa -- retain more of the nutrient-dense bran and germ.

I think the issue here is that when people eat a lot of whole grains they
aren't eating a lot of refined grains, which are comparatively even worse.

One can also eat the germ and bran from grains without eating the starchy
endosperm.

Forgot to add that whole wheat bread is quite good for chin wiping.

Should we do a nutrition comparo again to see how well your precious whole
grains stand up to scrutiny? Once again, it is possible to have excellent
heart health without wholegrains. I know that takes a while to sink in Kurt.
If you as a type 1 who doesn't have an insulin resistance problem feel the
need to "bulk up" then by all means do so. If you feel the dangers of
insulin resistance has no bearing on heart health then so be it. Why don't
you go push your wholegrain agendas on someone with celiac disease? Do you
feel insulin resistance is better for the health than celiac disease? Do you
know how to reduce insulin resistance? Do you know the benefits of reducing
insulin resistance? perhaps if you got your brown nose out of the ADA pages
once in a while you might actually learn something worthwhile.

Actually, if he felt intellectually capable of reading some of the ADA
stuff, he might actually learn something worthwhile.

Hi Kurt,
seen this ?

J Nutr. 2007 Jun;137(6):1401-7.

Whole-grain foods do not affect insulin sensitivity or markers of lipid
peroxidation and inflammation in healthy, moderately overweight subjects.

High intakes of whole grain foods are inversely related to the incidence of
coronary heart diseases and type 2 diabetes, but the mechanisms remain
unclear. Our study aimed to evaluate the effects of a diet rich in whole
grains compared with a diet containing the same amount of refined grains on
insulin sensitivity and markers of lipid peroxidation and inflammation. In a
randomized crossover study, 22 women and 8 men (BMI 28 +/- 2) were given
either whole-grain or refined-grain products (3 bread slices, 2 crisp bread
slices, 1 portion muesli, and 1 portion pasta) to include in their habitual
daily diet for two 6-wk periods. Peripheral insulin sensitivity was
determined by euglycemic hyperinsulinemic clamp tests. 8-Iso-prostaglandin
F(2alpha) (8-iso PGF(2alpha)), an F(2)-isoprostane, was measured in the
urine as a marker of lipid peroxidation, and highly sensitive C-reactive
protein and IL-6 were analyzed in plasma as markers of inflammation.
Peripheral insulin sensitivity [mg glucose . kg body wt(-1) . min(-1) per
unit plasma insulin (mU/L) x 100] did not improve when subjects consumed
whole-grain products (6.8 +/- 3.0 at baseline and 6.5 +/- 2.7 after 6 wk) or
refined products (6.4 +/- 2.9 and 6.9 +/- 3.2, respectively) and there were
no differences between the 2 periods. Whole-grain consumption also did not
affect 8-iso-PGF(2alpha) in urine, IL-6 and C-reactive protein in plasma,
blood pressure, or serum lipid concentrations. In conclusion, substitution
of whole grains (mainly based on milled wheat) for refined-grain products in
the habitual daily diet of healthy moderately overweight adults for 6-wk did
not affect insulin sensitivity or markers of lipid peroxidation and
inflammation.

Hi Gys,

No, I hadn't seen that study. As usual, for every study posted here
there is probably at least one somewhere else that contradicts it.
Given the fact that the "whole grains are bad" group here is pretty
vocal I thought it would be good to give a counterpoint to that point.

In the study you referenced above there were a couple of factors that
made me less than enthsiastic about it:

- It used a small sample of 22 women and 8 men who were said to be
"healthy moderately overweight."

- The "whole grains" used in the study was mainly milled wheat

- It did not mention the quality of other foods consumed during the 6
week period

- It did not mention the amount of exercise the group did

Just my take on the study. Again, thanks for posting it. I never
mind an alternate opinion or study to what I post as long as one can
do it without the vindictive nature that so many here have. Your
never seem to have tha...unless I am not interpreting them
correctly.

My take on your study is that you don't consider type 2 diabetes and its
high IR when you jump in with a pro grains cite. Gys's actually is about
diabetics. You don't seem to understand IR at all.

"Low-Carbohydrate-Diet Score and the Risk of Coronary Heart Disease in Women
Results During 20 years of follow-up, we documented 1994 new cases of
coronary heart disease. After multivariate adjustment, the relative risk of
coronary heart disease comparing highest and lowest deciles of the
low-carbohydrate-diet score was 0.94 (95% confidence interval [CI], 0.76 to
1.18; P for trend=0.19). The relative risk comparing highest and lowest
deciles of a low-carbohydrate-diet score on the basis of the percentage of
energy from carbohydrate, animal protein, and animal fat was 0.94 (95% CI,
0.74 to 1.19; P for trend=0.52), whereas the relative risk on the basis of
the percentage of energy from intake of carbohydrates, vegetable protein,
and vegetable fat was 0.70 (95% CI, 0.56 to 0.88; P for trend=0.002). A
higher glycemic load was strongly associated with an increased risk of
coronary heart disease (relative risk comparing highest and lowest deciles,
1.90; 95% CI, 1.15 to 3.15; P for trend=0.003).

Conclusions Our findings suggest that diets lower in carbohydrate and higher
in protein and fat are not associated with increased risk of coronary heart
disease in women. When vegetable sources of fat and protein are chosen,
these diets may moderately reduce the risk of coronary heart disease."

Hi Kurt,
well actually that is the core buisiness of science itself.....You will
always find a contradicting study because science does experiments to
increase the total amount of knowledge of the human race.Science is also a
pear reviewed enterprise : anybody can join in either with new experiments
or with new insights.Very often old experiments are repeated to control
their validity.So yes : you will always find a contradicting study.

But :
1) Thinking about it , joining the process and synthesizing your own
hypothesis is the fun of it
2) Your contribution will only be judged by the facts , not by who you are
3) In terms of effect the scientific enterprise is the best human kind has
come up with.The Egyptians worshipped the sun .After 4,000 years of a stable
society they did not even had a steam engine or a plastic rain coat.So for
me science is a better knowledge system than religion

If you have red the above you will not be surprised that I agree with you :
science _needs_ people who don't agree otherwise the process will stop....

Very good points Kurt , precisely the points that made me less enthousiastic
about it.I posted it because for me the connection between diabetes and
carbohydrates is intruiging ; I want to know all about it.

Hi Kurt,
here is another confusing parameter : the effect of your diet depends on
your insulin response.....Who would have predicted that....The article is on

Effects of a Low-Glycemic Load vs Low-Fat Diet in Obese Young Adults

Here is the abstract :

JAMA. 2007 May 16;297(19):2092-102.

Effects of a low-glycemic load vs low-fat diet in obese young adults: a
randomized trial.

CONTEXT: The results of clinical trials involving diet in the treatment of
obesity have been inconsistent, possibly due to inherent physiological
differences among study participants. OBJECTIVE: To determine whether
insulin secretion affects weight loss with 2 popular diets. DESIGN, SETTING,
AND PARTICIPANTS: Randomized trial of obese young adults (aged 18-35 years;
n = 73) conducted from September 2004 to December 2006 in Boston, Mass, and
consisting of a 6-month intensive intervention period and a 12-month
follow-up period. Serum insulin concentration at 30 minutes after a 75-g
dose of oral glucose was determined at baseline as a measure of insulin
secretion. Outcomes were assessed at 6, 12, and 18 months. Missing data were
imputed conservatively. INTERVENTIONS: A low-glycemic load (40% carbohydrate
and 35% fat) vs low-fat (55% carbohydrate and 20% fat) diet. MAIN OUTCOME
MEASURES: Body weight, body fat percentage determined by dual-energy x-ray
absorptiometry, and cardiovascular disease risk factors. RESULTS: Change in
body weight and body fat percentage did not differ between the diet groups
overall. However, insulin concentration at 30 minutes after a dose of oral
glucose was an effect modifier (group x time x insulin concentration at 30
minutes: P = .02 for body weight and P = .01 for body fat percentage). For
those with insulin concentration at 30 minutes above the median (57.5
microIU/mL; n = 28), the low-glycemic load diet produced a greater decrease
in weight (-5.8 vs -1.2 kg; P = .004) and body fat percentage (-2.6%
vs -0.9%; P = .03) than the low-fat diet at 18 months. There were no
significant differences in these end points between diet groups for those
with insulin concentration at 30 minutes below the median level (n = 28).
Insulin concentration at 30 minutes after a dose of oral glucose was not a
significant effect modifier for cardiovascular disease risk factors. In the
full cohort, plasma high-density lipoprotein cholesterol and triglyceride
concentrations improved more on the low-glycemic load diet, whereas
low-density lipoprotein cholesterol concentration improved more on the
low-fat diet. CONCLUSIONS: Variability in dietary weight loss trials may be
partially attributable to differences in hormonal response. Reducing
glycemic load may be especially important to achieve weight loss among
individuals with high insulin secretion. Regardless of insulin secretion, a
low-glycemic load diet has beneficial effects on high-density lipoprotein
cholesterol and triglyceride concentrations but not on low-density
lipoprotein cholesterol concentration. TRIAL REGISTRATION:
clinicaltrials.gov Identifier: NCT00130299.

It's a metareview. All it's saying basically is that other studies
have been telling us this kind of thing for years.

In other words what they're saying is that folk who ate more whole
grains did better than folk who ate less. What would those who weren't
eating the whole grains have been eating instead? The refined grains
that most people eat. In other words, switching from refined grains to
whole grains benefits your health in many ways.

As I'm sure you've noticed, there's not a lot of eating of
refined grain products goes on round here. In addition to which we're
diabetics. So why on earth bother to post something like this to
asd?

Philip Mellen, the lead author of the study Kurt cited, does. He's
published a number of studies which quite specifically take it into
account. But the metareview which Kurt cited doesn't, and wasn't
intended to. Kurt cited a general metareview of the difference in
health between eating refined grains and whole grains, ignoring other
aspects of nutrition, ignoring exercise, ignoring diabetes, even
ignoring metabolic syndrome and insulin resistance. Yet the relevance
of such criteria to asd are known to Kurt, because he uses them in
criticising studies cited by other people.

Weird.

especially in America where a lot of "whole wheat" breads still
contain a great deal of processed white flour.

Read the labels very carefully.

Grain breads shouldn't even be in the "wholegrain group".

Count the wholegrain pieces in a piece of grain bread. Compare that to the
number of brown rice grains in a serving - similar carbs.
