Cholesterol scare tactics from both the media and the medical community. They have the people feeling guilty over their breakfast choices.
They used to breed Hogs for Lard. Cajun Chef was giving a class on gumbo and he said Lard had less saturated fat than butter. He was making roux. No idea if it's true.
Remember the moive, "My Cousin Vinnie ?" There was a scene where they are ordering breakfast and the cook floats a brick of Lard over the flat top. The actors react in horror. (Typical of East Coast Elite)
