The correct answer is A) 1 and 2 only.
Maintaining good cardiovascular health involves managing blood lipid levels.
1. Low cholesterol level: Generally, lower levels of total cholesterol are desirable. More specifically, low levels of LDL (“bad” cholesterol) are important.
2. High HDL level: High-density lipoprotein (HDL) is often called “good” cholesterol because it helps remove other forms of cholesterol from your bloodstream. High levels of HDL are protective against heart problems.
3. High VLDL level: Very low-density lipoprotein (VLDL) contains a high concentration of triglycerides. High levels of VLDL are associated with an increased risk of heart disease. This is undesirable.
4. High LDL level: Low-density lipoprotein (LDL) is often called “bad” cholesterol because it can contribute to the buildup of plaque in arteries. High levels of LDL are a major risk factor for heart disease. This is undesirable.
Therefore, to prevent heart problems, a normal healthy person should aim for low overall cholesterol (specifically low LDL) and high HDL.
Cholesterol and triglycerides are fats (lipids) that are transported in the blood by lipoproteins. HDL, LDL, and VLDL are types of lipoproteins. A lipid profile test measures levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides, which helps assess the risk of cardiovascular disease.
