COLUMBUS, Ohio A daily dose of safflower oil, a common cooking oil, for 16 weeks can improve such health measures as good cholesterol, blood sugar, insulin sensitivity and inflammation in obese postmenopausal women who have Type 2 diabetes, according to new research.
This finding comes about 18 months after the same researchers discovered that safflower oil reduced abdominal fat and increased muscle tissue in this group of women after 16 weeks of daily supplementation.
This combination of health measures that are improved by the safflower oil is associated with metabolic syndrome, a cluster of symptoms that can increase risk for cardiovascular disease and diabetes.
These new findings have led the chief researcher to suggest that a daily dose of safflower oil in the diet about 1 2/3 teaspoons is a safe way to help reduce cardiovascular disease risk.
"The women in the study didn't replace what was in their diet with safflower oil. They added it to what they were already doing. And that says to me that certain people need a little more of this type of good fat particularly when they're obese women who already have diabetes," said Martha Belury, professor of human nutrition at Ohio State University and lead author of the study.
"I believe these findings suggest that people consciously make sure they get a serving of healthy oil in their diets each day maybe an oil and vinegar dressing on a salad, or some oil for cooking. And this recommendation can be extended to everyone."
The research appears online and is scheduled for future print publication in the journal Clinical Nutrition.
Safflower oil contains linoleic acid, which is a PUFA -- a polyunsaturated fatty acid. Research dating back to the 1960s has suggested that these dietary oils from plant sources can help prevent heart disease, said Belury, who holds the Carol S. Kennedy professorship in nutrition. But attention to these fats has d
