Cholesterol is a vital nutrient for healthy body function. Cholesterol is used by the body in the manufacture of the hormones testosterone, estrogen, progesterone to name just a few. This list is by no means complete. It is also used in myelin sheath formation (covering for nerves). The liver makes approximately 90 percent of the body’s daily cholesterol requirement. The remaining 10 percent is obtained from dietary sources.
Cholesterol is usually transported around the body in the blood bound to different proteins. There are two types of protein called HDL (High Density Lipoprotein) or LDL (Low Density Lipoprotein). High LDL, in conjunction with a low HDL has been associated with atherosclerotic plaque formation and hence has been linked to cardiovascular disease. Atherosclerotic plaque formation on the arterial walls causes hardening and narrowing of the arteries which can lead to heart attack and stroke.
HDLs carry the cholesterol in the blood and from artery walls to the liver, where it is then excreted through the bile. Therefore, you need to have a high HDL cholesterol level (HDL-C) and a low LDL (LDL-C) cholesterol level to reduce the risk of cardiovascular disease.
Fiber is known to bind dietary fat and cholesterol in the gut and thus inhibit their absorption by the body. Increase your intake of anti-oxidants like beta-carotene (a vitamin A precursor), vitamins C and E, soy products, green or black tea to help fight high cholesterol. Anti-oxidants are believed to slow down the development of atherosclerosis. Beta-carotene and vitamin C can be found in citrus fruits and in red, orange and dark green vegetables. Vitamin E is found mainly in cold-pressed oils and nuts.
