Is it true that Cholesterol is a waxy substance found primarily in green vegetables.?

False.

Cholesterol is a waxy substance that is mainly produced in the liver and is needed by the body for maintaining healthy cell walls, producing vitamin D, and synthesizing hormones. It can also be obtained from animal-based foods such as meat, dairy, and eggs. However, it is important to note that green vegetables do not typically contain high levels of cholesterol.
