Trans fats

Options
I'm not proud to admit it but about 1/3 of my weeks food intake comes from fast food and restaurants. From what I know, trans fats = bad. But I just read that trans fats occur in nature and in meat. I don't understand. Is trans fat bad because it's man made and it's supposed to make food more shelf-stable? But if it's man made, how does it occur in nature?
