Final answer:
Replacing saturated fat with monounsaturated fat can help to lower LDL without lowering HDL.
Step-by-step explanation:
Replacing saturated fat with monounsaturated fat can indeed help to lower LDL without lowering HDL. Unsaturated fatty acids, such as monounsaturated fats, are associated with a lower level of LDL cholesterol and a lower risk of heart disease. Consuming a diet rich in mono- and polyunsaturated fats can contribute to healthy blood cholesterol levels.
