Trans fat will be reduced but not eliminated from foods, so FDA will continue to require it on the label. In 2015, the FDA published a final determination that partially hydrogenated oils (PHOs), the source of artificial trans fat, are not generally recognized as safe, but this determination would not affect naturally occurring trans fat, which would still exist in the food supply. Trans fat is present naturally in food from some animals, mainly ruminants such as cows and goats. Also, industry can currently use some oils that are approved as food additives and can still petition FDA for certain uses of PHOs.
