Trans fats are associated with which cardiovascular effect and foods containing them?

Raise HDL and lower LDL Have no effect on cholesterol Only affect triglycerides Raise LDL and lower HDL

Correct Answer:

Raise LDL and lower HDL

Explanation:

Trans fats disrupt cholesterol in a way that harms heart health: they raise LDL, the “bad” cholesterol, and lower HDL, the “good” cholesterol. This combination worsens the lipid profile and increases the risk of plaque buildup in arteries, which is a key driver of cardiovascular disease. That makes the described effect—raising LDL and lowering HDL—the best match for how trans fats influence heart health. Trans fats are commonly found in foods made with partially hydrogenated oils, such as some commercially baked goods, fried foods, and certain margarine products. Because of their impact on LDL and HDL, avoiding trans fats is strongly recommended for cardiovascular health.
