The other oils, mainly sunflower oil, also were protective
compared with palm oil. Although the trans fatty acid content
of adipose tissue of users of other oils was comparable to that
of users of soybean oil with less trans fatty acids, their -linolenic
acid content was lower. It is possible that this lower
-linolenic acid accounts in part for the difference in OR
when palm oil is compared with soybean oil (OR 1.33; 95%
CI: 1.08 –1.63) or other oils (OR 1.23; 95% CI: 0.99 –1.52).
