Oats May Help Prevent Clogged Arteries
BOSTON--Already known for their ability to help lower cholesterol levels,
oats may have additional cardiovascular benefits. A compound contained in oats
may keep blood cells from sticking to artery walls, helping to prevent clogged
arteries and atherosclerosis, according to new research published in the June
issue of Agricultural Research magazine (www.ars.usda.gov/is/AR).
Researchers from the Jean Mayer USDA (U.S. Department of Agriculture) Human
Nutrition Research Center on Aging (HNRCA) at Tufts University in Boston
purified avenanthramides from oats and exposed them to human arterial wall cells
for 24 hours. While observing the mixture under incubation, researchers found
significant reductions in both the expression of adhesion molecules (that glue
blood cells to artery walls) and the sticking of blood cells to arterial wall
cells. They concluded the adhesion suppression by the oat-compound may prevent
the narrowing of artery walls caused by a buildup of blood cells and
inflammation, which eventually leads to atherosclerosis.
Research has also proven fiber from oats helps reduce LDL cholesterol,
reiterating the heart-healthy benefits of oats. Adding oat products as part
of an overall healthy diet and cutting down on high-fat, high-cholesterol foods
are important to gaining these benefits, said Mohsen Meydani, DVM, Ph.D.,
nutritionist and lead researcher of the study.
