Hey Jody, as recently as today, the FDA has ruled that trans fats (partially hydrogenated oils) are no longer “generally recognized as safe.) Once this is finalized, then these will become food additives that cannot be used in food without their approval.
So what foods contain this unsafe ingredient? Things like frozen pizza, donuts, frozen desserts, margarine, coffee creamer, microwave popcorn, cake mixes, Bisquick, soups, fast food fries and chicken, cookies, chips, crackers, cereals, cookies, candy, dips, dressings, whipped toppings.
The downside – if you are eating these things, you will have to find alternatives. The upside – you will be healthier for it.
