MONDAY, Nov. 1 (HealthDay News) -- The success of a
low-cholesterol diet can be improved by adding monounsaturated fat
(MUFA), which are commonly found in nuts, seeds, avocados, and oils
such as olive oil, canola oil and sunflower oil, new research
In the study, researchers randomly assigned 17 men and seven
postmenopausal women with mild to moderate elevated cholesterol
levels to either a high-MUFA diet or a low-MUFA diet.
Both groups consumed a vegetarian diet that included oats,
barley, psyllium, eggplant, okra, soy, almonds and a plant
sterol-enriched margarine. In the high-MUFA group, the researchers
substituted 13 percent of calories from carbohydrates with a
high-MUFA sunflower oil, with the option of a partial exchange with
In the high-MUFA group, levels of "good" cholesterol
(high-density lipoprotein cholesterol, or HDL) increased 12.5
percent while levels of "bad" cholesterol (low-density lipoprotein
cholesterol or LDL) decreased 35 percent, according to the report
in the Nov. 1 issue of
CMAJ, the Canadian Medical Association Journal.
People with low HDL levels and high LDL levels are at increased
risk for cardiovascular disease, Dr. David Jenkins of the Clinical
Nutrition and Risk Factor Modification Center at St. Michael's
Hospital in Toronto, and colleagues explained in a news release
from the journal's publisher.
"The addition of MUFA increased [HDL] and therefore may further enhance the cardioprotective effect of the cholesterol-lowering dietary portfolio without diminishing its cholesterol-lowering effect," Jenkins and colleagues wrote.
Monounsaturated fats are commonly consumed in what is known as
the Mediterranean diet, noted the researchers, who added that
exercise, moderate alcohol consumption, not smoking and weight loss
can also help raise "good" HDL cholesterol.
