Feb. 25, 2008 -- A diet rich in whole grains may help fight your belly bulge
while lowering the risk of heart disease.

I was going to leave this to Quentin, but then I found the
abstract here:
http://www.ajcn.org/cgi/content/abstract/87/1/79

I'll take a risk and repeat it all, without the journalist's
hyperbole from the above link. I can't access the full text,
but I doubt we need to.

To cut to the chase the problem is in the design:

"Design: Obese adults (25 M, 25 F) with metabolic syndrome
were randomly assigned to receive dietary advice either to
avoid whole-grain foods or to obtain all of their grain
servings from whole grains for 12 wk. All participants were
given the same dietary advice in other respects for weight
loss."

I doubt any of us are surprised that whole grains were
better. But where were the other comparison groups of lower
or higher whole grain input? Or no grains at all?

Here 'tis:

The effects of a whole grain–enriched hypocaloric diet on
cardiovascular disease risk factors in men and women with

Background: Whole-grain foods are associated in
observational studies with a lower body mass index and lower
cardiovascular disease (CVD) risk. However, few clinical
trials have tested whether incorporating whole grains into a
hypocaloric diet increases weight loss and improves CVD risk
factors.

Objective: The aim of this study was to determine whether
including whole-grain foods in a hypocaloric (reduced by 500
kcal/d) diet enhances weight loss and improves CVD risk
factors.

Design: Obese adults (25 M, 25 F) with metabolic syndrome
were randomly assigned to receive dietary advice either to
avoid whole-grain foods or to obtain all of their grain
servings from whole grains for 12 wk. All participants were
given the same dietary advice in other respects for weight
loss.

Results: Body weight, waist circumference, and percentage
body fat decreased significantly (P < 0.001) in both groups
over the study period, but there was a significantly (P =
0.03) greater decrease in percentage body fat in the
abdominal region in the whole-grain group than in the
refined-grain group. C-reactive protein (CRP) decreased 38%
in the whole-grain group independent of weight loss but was
unchanged in the refined-grain group (P = 0.01 for group x
time interaction). Total, LDL, and HDL cholesterol decreased
in both diet groups (P < 0.05). Dietary fiber and magnesium
intakes increased in the whole-grain but not the
refined-grain group (P = 0.007 and P < 0.001, respectively,
for group x time interaction).

Conclusions: Both hypocaloric diets were effective means of
improving CVD risk factors with moderate weight loss. There
were significantly (P < 0.05) greater decreases in CRP and
percentage body fat in the abdominal region in participants
consuming whole grains than in those consuming refined
grains."
