Brief Summary

While the deleterious effects of trans fat from industrial sources (iTFA) on cardiovascular health are well established, the impact of TFA from ruminants (rTFA) on cardiovascular risk factors has not been as well characterized. We have previously shown in men that a very high dietary intakes of rTFA (\>3.5% of energy) leads to unfavourable changes in lipid cardiovascular risk factors that are similar to those seen with iTFA. However, our data also indicated that achievable intakes of rTFA that remain well above the current human consumption (1.5% of energy intake) had neutral effects on plasma lipids and other cardiovascular disease (CVD) risk factors in men. Other studies have also suggested that the LDL and HDL response to very high dietary intakes of rTFA (\>5% of energy) in women may be different than in men. The general objective of the study is to investigate for the first time in a double-blind randomized controlled study the impact of high but yet achievable intake of ruminant trans fatty acids on plasma LDL-Cholesterol and other risk factors for CVD in healthy women.
