The reason it's called saturated fat is because it it fully saturated with hydrogen. But might there be a better label? What if calling it "saturated fat" has had a major influence on how people perceive what it actually is? Think about it...
What would most people think of? Fat sitting in a pool of grease... (as in "Saturated" with grease?) I think this is why people are so quick to accept the idea that saturated fat is terrible for you and clogs your arteries. The mental image that the name itself induces is likely not positive.
Might the world's view of the fat types be radically amended if we had chosen to name it something more understandable?
Saturated Fat >>> Whole Stable Fat
Monounsaturated Fat >>> Stable Fat
Polyunsaturated Fat >>> Unstable Fat
