When cholesterol levels are above normal limits and remained high cholesterol remnantsare deposited in the arteries and through the years, they are hardened by a fatty substancecalled cholesterol plaque that accumulates on the walls of the arteries and reduces orblocks blood flow.
Organs supplied by these arteries are damaged because they can not get oxygen and nutrients needed by limiting blood flow through the arteries, so for example, when theblood flow to the brain is blocked, there is a stroke or plaque completely blocks a coronary artery, is when we are in presence of a heart attack.
Cholesterol in the body comes from two sources, most of it is produced by the liver fromvarious nutrients and especially saturated fat.
The liver produces most of the cholesterol your body needs and given that all animals can make their own cholesterol, some of that cholesterol is incorporated into the human bodyby eating animal products.
These foods include meats, egg yolks, organ meats, whole milk and dairy products, whichwhen ingested your cholesterol is absorbed by the intestine and is added to the liver.
It is also known that a diet high in saturated fat appears to increase the production of cholesterol in the body. Therefore, reduction of dietary cholesterol and fat helps keepcholesterol levels in the blood within a healthy range.
