The recommendation to limit saturated fat intake to less than 10% of daily caloric intake is based on extensive research linking high saturated fat consumption to increased levels of LDL cholesterol (often referred to as "bad" cholesterol) and an elevated risk of cardiovascular disease. Saturated fats are predominantly found in animal products such as fatty cuts of meat, full-fat dairy products, and some plant oils like coconut and palm oil.

Reducing saturated fat consumption is often part of dietary guidelines aimed at promoting heart health and preventing chronic diseases. Therefore, emphasizing the limitation of saturated fats is crucial for a balanced, heart-healthy diet.

The other types of fats play different roles in health; for instance, trans fats are also considered harmful but the context provided in dietary guidelines emphasizes saturated fat specifically. Additionally, cholesterol intake is generally less emphasized in recent dietary recommendations, as it has been found that dietary cholesterol does not have as significant an impact on blood cholesterol levels for most individuals as previously thought. Monounsaturated fats, on the other hand, are associated with various health benefits, including improved heart health, and they do not have a restriction applied to them in the same way that saturated fat does.
