The World Health Organization recommends limits on trans fat of less than 1 to 2 grams a day-in this context, it’s easy to see that 0.6 grams is not an insignificant contribution. A 2012 study conducted by FDA scientists estimated that refined oil contributes an average 0.6 grams of trans fat a day (Doell 2012). Artificial trans fats are generated in refined oils when they are processed at high temperatures from the crude oil into a bland, odorless, colorless oil (Greyt 1999).

Both refined oils and fully hydrogenated oils contain small amounts of unhealthy artificial trans fats and contribute to the total intake of trans fat in the diet (Biofortis 2014).
