Basically, trans fats were created by manufacturers in the early 1900's. It's a method called 'hydrogenation' which makes liquid fats, solid. This allows foods to have a longer, more stable shelf life, as well as help maintain flavor stability. So, we see it everywhere in the food labels, 'partially hydrogenated oil.' Yup, that's trans fat. Mostly, because this fat is a manufactured fat, we're most commonly going to see it in processed foods: cakes, cookies, chips, and most other snack foods. I suppose that's partially why they tastse so good! Trans fats are also found in minimal quantities in animal based foods. So, as we already knew, we want to minimize our intake of animal fat.
But why are trans fats so bad for us? Like saturated fats, it raises our LDL, or bad cholesterol, which can lead to heart disease and ultimately heart failure. Now we have to pay attention to both our saturated fat intake as well as trans fat intake. Lowering our intake of one fat, may result in higher intake of the other. As consumers, we can really only rely on ourselves to read the labels, but we have to know how to read them to get the most benefit from the information we're being provided. Hopefully, you'll now be able to make slightly more educated choices the next time you're at the store.
