What is the main dietary source of cholesterol?

Cholesterol is a type of lipid that is found predominantly in animal products, making them the primary dietary source of cholesterol. Foods such as meat, dairy, and eggs contain notable levels of cholesterol. This is because cholesterol is essential for various biological functions in animals and is synthesized in their bodies.

Plant-based foods, including vegetables, fruits, and grains, do not contain cholesterol, as they do not have the biological mechanisms to synthesize it. Instead, they are often rich in fiber and other nutrients but lack the cholesterol found in animal-derived foods. Understanding this distinction is crucial for dietary planning, especially for individuals looking to manage their cholesterol levels.
