Trans Fat Linked to Heart Disease
Posted on: Wednesday, 28 March 2007, 15:00 CDT
U.S. women with the highest levels of trans fat in their blood had three times the risk of coronary heart disease as those with the lowest levels, a study says.
The study, published online and in the April 10 print issue of Circulation: Journal of the American Heart Association, used blood samples collected in 1989 and 1990 from 32,826 participants in the Brigham and Women's Hospital-based Nurses' Health Study.
The study is particularly strong because the trans fatty acid levels -- found mainly in partially hydrogenated vegetable oils widely used by the food industry -- were measured in blood samples from the study population, according to study leader Frank Hu, an associate professor of nutrition and epidemiology at Harvard School of Public Health in Boston.
These data provide further justifications for current efforts to remove trans fat from foods and restaurant meals, Hu said in a statement. Trans fat intake in the U.S. is still high, and reducing trans fat intake should remain an important public health priority.
