Trans fatty acids and plasma lipoproteins

Perceptions of the health effects of trans fatty acids, particularly in the form of margarine, have undergone several changes during the past 10 years . What was once heralded as the healthy alternative to butter now assumes t he role of co-conspirator. A new study finds that consumption of trans fatt y acids, such as those found in stick margarine and shortening, have negati ve effects on lipoprotein profiles that are comparable to those of saturate d fatty acids. In the prevention and treatment of cardiovascular diseases, therefore, it is recommended that consumers reduce intakes of both saturate d and trans fatty acids.
