Which of the following is a recommendation for lowering undesirably high levels of blood lipids?

• A. Reduce complex CHO intake
• B. Limit saturated fatty acid intake to 30% of total calories
• C. Consume a minimum of 500mg of dietary cholesterol per day
• D. Replace saturated fatty acids with monounsaturated or polyunsaturated fatty acids

Answer: (D)

Replacing saturated fatty acids with monounsaturated or polyunsaturated fatty acids is the most effective way to lower undesirably high blood lipids. Saturated fats tend to raise LDL cholesterol, the main driver of atherogenic risk, while unsaturated fats help lower LDL and can improve the overall lipid profile. By substituting MUFAs and PUFAs for saturated fats, you improve lipid levels without necessarily adding calories, and you can also gain benefits from the cardiovascular-friendly fats found in olive oil, canola oil, nuts, seeds, and fatty fish.

Choices that focus on reducing complex carbohydrates or limiting saturated fat to a high percentage miss the most impactful strategy or use a target that’s not as effective. Eating a lot of cholesterol (like 500 mg per day) isn’t a reliable or recommended way to manage blood lipids for most people.
