AA fall in low-density lipoproteins in the blood
BA rise in low-density lipoproteins in the blood
CA fall in the triglyceride content of the blood
DA rise in the fluid nature of the cell membrane
Answer & Solution
Correct answer: B. A rise in low-density lipoproteins in the blood
1. Trans fats are formed artificially when oils are hydrogenated.
2. An increase in trans fats in the human diet may lead to an increase in low-density lipoproteins, the bad cholesterol.
3. Higher LDL may in turn lead to plaque deposition in the arteries and heart disease.
4. This is why many fast food restaurants banned trans fats and why food labels must display trans fat content.
5. A fall in LDL is the effect credited to unsaturated fats, which lower blood cholesterol, so that option belongs to the other fat type.
