c. B-complex vitamins
d. Vitamin K
A
Low-density lipoproteins (LDLs) transport cholesterol to body cells. Diets high in saturated fats increase LDL circulation in the bloodstream and may result in fatty deposits on vessel walls, causing cardiovascular disease. As a result, LDL is often known as the "bad cholesterol." High-density lipoproteins (HDLs) remove cholesterol from the bloodstream, returning it to the liver, where it is used to produce bile; thus, a high HDL is considered protective against cardiovascular disease. It is often known as the "good cholesterol." Vitamin K is involved in blood clotting. B-complex vitamins' primary function is cellular metabolism. Linolenic acid (omega-3) helps to protect against heart disease but does not indicate cardiovascular disease.
