Sure animal foods—liver, egg yolk, dairy fats, glandular organ meats, and mind— are particularly high in ldl cholesterol. This free form of ldl cholesterol is the one kind that intestinal cells are able to take in.
Egg yolks include concentrated ldl cholesterol as a result of the rising child chick wants it to construct new cells. Milk fat comprises plenty of cholesterol because the rising baby calf wants it to build new cells.
