Elaidic acid is the major trans fat found in hydrogenated vegetable oils and occurs in small amounts in caprine and bovine milk (very roughly 0.1 % of the fatty acids)cite journal |author=Alonso L, Fontecha J, Lozada L, Fraga MJ, Juárez M |title=Fatty acid composition of caprine milk: major, branched-chain, and trans fatty acids |journal=J. Dairy Sci. |volume=82 |issue=5 |pages=878–84 |year=1999 |pmid=10342226 |doi=] . It is the trans isomer of oleic acid.

Elaidic acid increases CETP activity, which in turn raises VLDL and lowers HDL cholesterol.cite journal
