Trans fats are commonly used by restaurants, fast food chains and companies that produce food on a large scale and for commercial purposes, as it is cheaper. Most processed foods, store-bought cakes, biscuits and fast food such as pizzas, burgers and fries, etc have this kind of fat. It is rightly called bad fat as it increases the levels of low density lipo-protein or bad cholesterol in our body. This is the kind of fat that is best avoided.
