Which type of fat is known to reduce LDL cholesterol levels?

Saturated fat
Monounsaturated fat
Trans fat
Polyunsaturated fat

The correct answer is: Monounsaturated fat

Monounsaturated fat is recognized for its ability to help reduce LDL cholesterol levels, often referred to as "bad cholesterol." Including monounsaturated fats in the diet can lead to a healthier blood lipid profile, which is important for heart health. Foods rich in monounsaturated fats, such as olive oil, avocado, and certain nuts, provide health benefits by improving cholesterol levels and may also assist in reducing the risk of heart disease. In contrast, saturated fats, found in animal products and some plant oils, can raise LDL cholesterol levels when consumed in excess. Trans fats are artificial fats that can significantly increase LDL cholesterol and lower HDL ("good") cholesterol, contributing to cardiovascular disease risk. Polyunsaturated fats, while beneficial as they can lower LDL cholesterol, are not as specifically emphasized for cholesterol reduction as monounsaturated fats. Therefore, opting for monounsaturated fats is a proven strategy for improving heart health by managing cholesterol levels effectively.
