What is the difference between a saturated fat and a unsaturated fat? Which one is good for the body and which one is bad?
A saturated fat contains only single bonds, it stacks easily and because it stacks easily it is bad for the body. It hardens at room temperature. A unsaturated fat contains double and triple bonds, is very hard to stack an because it is hard to stack it is good for the body. It is liquid at room temperature.
