Which statement about cholesterol is NOT true?

• A. Cholesterol is needed for cell membranes and production of hormones.
• B. Cholesterol is a form of lipid.
• C. The majority of the cholesterol we need is produced by the liver.
• D. LDL is a good form of cholesterol that helps reduce disease.

Answer: (A)

Cholesterol is a lipid that plays essential roles in cell membranes and hormone production. The liver makes most of the cholesterol the body needs, with dietary cholesterol contributing less than people often think. LDL, low-density lipoprotein, is generally considered the “bad” cholesterol because high levels can lead to plaque buildup in arteries, while HDL, the “good” cholesterol, helps remove cholesterol from the bloodstream. So the statement that LDL is a good form of cholesterol that helps reduce disease is not true; the statements that cholesterol is a form of lipid, that most cholesterol comes from the liver, and that it’s needed for membranes and hormone production are correct.
