摘要

During the past 17 years, there has been a tremendous interest in the nutritional characteristics of trans fatty acids (TFAs). There are two primary reasons for this activity. First, several human feeding studies have consistently observed that TFAs from partially hydrogenated vegetable oils (PHVO), at sufficiently high levels, raise blood LDL-choles-terol (LDL-C) to a similar degree as saturated fatty acids and, unlike saturated fatty acids, which raise plasma HDL-cholesterol (HDL-C), TFAs do not. Second, conjugated linoleic acid (CLA), a form of TFA containing a cis and trans double bond, has been shown to exhibit multiple health-related benefits.
