The Truth About Cholesterol

What is cholesterol and why do we need it?
Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body’s cells. It’s an important part of a healthy body because it’s used to form cell membranes. Cholesterol also aids in the manufacture of bile (which helps digest fats), and is also important for the metabolism of fat soluble vitamins, including vitamins A, D, E and K. It is the major precursor for the synthesis of vitamin D and of the various steroid hormones (which include cortisol and aldosterone in the adrenal glands, and the sex hormones progesterone, the various estrogens, testosterone, and derivatives ).
How could something so good be so bad?
Cholesterol has been wrongly accused because upon inspection of the arteries of someone at risk for a heart attack, levels of cholesterol and plaque build up are very high. Cholesterol is actually being transported to tissues as part of an inflammatory response that is there to repair damage. It will only lodge itself onto the artery and cause plaque if the artery has become damaged. Inflammation in the artery is what causes this damage. In fact, it is now known that the coronary disease that causes heart attacks is now considered to be caused mostly from chronic inflammation.
To blame cholesterol for heart attacks would be the equivalent of blaming increased police security in a high crime area. It was not the police that caused the crime, they were just placed there in response to the crimes.
