Chocolate-Flavored Cereal Lowers Cholesterol
In a recent study, the cereal raised HDL (good) cholesterol and lowered the ratio of LDL (bad) cholesterol as much as wheat bran. It also relieved constipation, researchers report in the Archives of Internal Medicine.
"A chocolate-flavored low-fat, high-fiber source, cocoa bran, has a beneficial effect on laxation and a potentially interesting action in maintaining HDL cholesterol levels," according to Dr. David J. A. Jenkins from the University of Toronto in Canada.
The Cacao Beans is a legume that has a high-fiber bran or seed coat. While the bran remains when the bean is processed into cocoa powder, the bran is discarded when the bean is used to make chocolate.
To test the effects of a cocoa-bran cereal on cholesterol and laxation, investigators fed healthy adults a cereal that provided 25 grams of fiber a day, for two weeks. For a comparison group, the study subjects then switched to eating a chocolate-flavored, low-fiber breakfast cereal that provided about 6 grams of fiber a day, for another two weeks.
Results show that HDL cholesterol rose by 7.6 percent and the ratio of LDL to HDL cholesterol fell by 6.7 percent after two weeks of eating the cocoa-bran cereal.
The low-fiber diet was associated with lower HDL cholesterol levels and higher LDL to HDL cholesterol ratios, the researchers observed. Unexpectedly, the low-fiber cereal also resulted in slightly lower blood pressure readings compared with the cocoa-bran diet.
"The effect on blood pressure, although small, requires confirmation and explanation of mechanism," Jenkins and colleagues conclude.
