“Trans fats seemed like such a good thing once, enhancing the flavor, texture, and shelf life of many processed foods — from cookies to frozen pizza. Unfortunately, they come with a health risk. Trans fatty foods tantalize your taste buds, then travel through your digestive system to your arteries, where they turn to sludge.
Small amounts of trans fats occur naturally in beef, lamb, and full-fat dairy products. But most come from processing liquid vegetable oil to become a solid fat.
As of 2006, food manufacturers have been required by the FDA to list trans fats on food labels.”
