Question

What is considered an optimal level of LDL cholesterol?

a. Greater than or equal to 190 mg/dL
b. Less than 100 mg/dL
c. Greater than or equal to 240 mg/dL
d. 160-189 mg/dL

Answer 1

An optimal level of LDL cholesterol is less than 100 mg/dL. High levels of LDL cholesterol increase the risk of heart disease, while high levels of HDL cholesterol reduce the risk.

Step-by-step explanation:

An optimal level of LDL cholesterol is considered to be less than 100 mg/dL. LDL cholesterol, often referred to as 'bad cholesterol,' carries cholesterol from the liver to other tissues in the body. High levels of LDL cholesterol increase the risk of heart disease and plaque formation in the arteries. On the other hand, high levels of HDL cholesterol, also known as 'good cholesterol,' collect cholesterol from the tissues and return it to the liver. A high level of HDL cholesterol is desirable as it helps reduce the risk of heart disease.
