What is the main source of dietary cholesterol?

The main source of dietary cholesterol comes from animal products. Foods such as meat, poultry, fish, eggs, and full-fat dairy products contain significant amounts of cholesterol because it is a substance that is produced naturally in animals. While the body itself also produces cholesterol, it is primarily sourced from animal-derived foods in the human diet.

In contrast, plant-based foods do not contain cholesterol, as cholesterol is exclusively found in animal tissues. Processed sugars and whole grains do not contribute to dietary cholesterol at all; they come from carbohydrates and fibers and contain no cholesterol whatsoever. Therefore, focusing on the intake of animal products is essential when considering dietary sources of cholesterol.
