BRAINCAKEDiet and Atherosclerosis
Diet affects the risk of atherosclerosis mainly through blood cholesterol, blood pressure and body mass.
Lipoproteins. Cholesterol is carried in the blood as lipoproteins. Low-density lipoproteins (LDL) carry cholesterol from the liver to the tissues. High LDL levels lead to cholesterol being deposited in artery walls, forming atheromas. High-density lipoproteins (HDL) carry cholesterol from the tissues back to the liver, where it can be removed. A high ratio of LDL to HDL increases the risk of CVD.
