What is Cholesterol?

Cholesterol is a natural fat-like substance that is made in the liver and found in foods containing animal products. About 80% of the cholesterol in your blood is made in your liver. Only about 20% of your blood cholesterol comes from the cholesterol found in foods.

Our body uses cholesterol to insulate nerves throughout the body, maintain cell walls and produce vitamin D, digestive juices, and certain hormones.

Problems with Blood Cholesterol

High blood cholesterol levels cause hard plaque to deposit on the inner walls of your blood vessels, causing them to narrow. This makes it difficult for blood to flow through the body. This can lead to blood clots, blocking the flow of blood to the brain or heart, causing a stroke or heart attack.
