Which of the following type of lipids (fats) have shown to increase the risk of heart disease by forming plaques of fat on blood vessels?

Unsaturated fats (HDL)

Omega 3 fatty acids

Omega 6 fatty acids

Saturated fats (LDL)

Answer and Explanation

The Correct Answer is D

A. Unsaturated fats (HDL): High-density lipoprotein (HDL) is considered "good cholesterol" because it helps remove LDL cholesterol from the blood, reducing the risk of heart disease.

B. Omega-3 fatty acids: Omega-3 fatty acids are healthy fats that reduce inflammation and lower the risk of heart disease by improving heart health.

C. Omega-6 fatty acids: While excessive omega-6 intake may contribute to inflammation, they are not the primary contributors to plaque buildup in blood vessels like saturated fats (LDL).

D. Saturated fats (LDL): Saturated fats increase low-density lipoprotein (LDL), also known as "bad cholesterol," which contributes to plaque buildup in arteries and increases the risk of heart disease.
