High-Fiber Diet Aids
Flowing of Blood Vessels
Researchers from Finland and the United States report evidence
that diets high in cereal fiber and whole-grain products may slow
the progression of atherosclerosis,
plaque build-up in the arteries, of postmenopausal women.
Several studies have linked increased dietary fiber, especially
cereal fiber, with a reduced risk of cardiovascular
disease and death, but most of them have been conducted in
patients without coronary artery disease and have not directly
assessed the effect of fiber intake on the progression of plaque
build-up in the arteries of patients with established heart disease.
Dr. Alice H. Lichtenstein from Tufts University in Boston and
colleagues looked at the effects of whole grain consumption in
229 postmenopausal women with coronary blockages of at least 30
percent who were participating in the Estrogen Replacement and
Atherosclerosis Trial. As part of study, a diet questionnaire
was used to estimate fiber intake.
Women consuming more than 3 grams of cereal fiber or more than
6 servings of whole grains per week over a 3-year period showed
modestly smaller declines in coronary artery blockage compared
with women with lower intakes of fiber per week, the group reports
in the American Heart Journal.
However, the differences in disease progression were almost that
same as that seen in patients treated with cholesterol-lowering
statin drugs, the investigators point out.
Lichtenstein stated: "There are now good data that women with
heart disease who reported consuming products made with whole
grains have slower rates of progression of their disease. This
conclusion is based on direct measures of (plaque) progression
over a three-year period."
"It is likely," Lichtenstein added, "the benefits of diets rich
in whole grains are applicable to a more general population."
