What exactly are trans fats? They are produced when liquid oils are processed into solid shortenings or partially hydrogenated oils which raise LDL or bad cholesterol and lower HDL or the good cholesterol.
Foods can really be full of trans fats is they are made of partially hydrogenated oils. Trans fats raise the bad cholesterol and increase heart disease risk.
Since even small amounts of trans fats are harmful to your health, your best bet is to avoid eating foods made with partially hydrogenated oil.
A person really needs to concentrate on eating foods that are whole. Such as fresh produce, fish liquid vegetable oils, and whole grains which are all trans fat-free.
