Sources of cholesterol?

Explanation:
Cholesterol comes from two main sources in the body: the liver naturally makes most of it (endogenous production), and we also obtain it from animal foods like meat and dairy. Plants don’t provide cholesterol (they have related compounds called phytosterols, not cholesterol). The brain does synthesize cholesterol for its own cells, but the liver is the primary source that supplies cholesterol to the rest of the body. So, the statement that cholesterol is produced by the liver and consumed in meat and dairy correctly reflects both internal production and dietary sources.
