If an oil is high in trans fats it might be harmful.
A small amount, I believe, is not a problem.
Hydrogenating an oil turns some of the polyunsaturated fats into trans fats.
If an oil contains a small amount of polyunsaturated fats, hydrogenating it cannot create a big amount of trans fats.
Coconut oil is usually 2% polyunsaturated fat, so hydrogenated coconut oil cannot be high in trans fats. I believe you can eat all the hydrogenated coconut oil you want and it will not cause an excess of trans fats.
Thanks. We buy the non-hydrogenated stuff.
But mostly we cook with olive oil, butter, or bacon grease.
(I”ve been wanting to spring for some duck fat, which is supposed to be great for things like French fries.)
