Cholesterol

Cholesterol – is it necessary? The short answer is “yes”, but it’s a little more complicated than just a simple yes or no answer.

Cholesterol is a vital component for the composition and maintenance of cell membranes and the synthesis of some hormones.  Cholesterol is also involved in the metabolism of certain vitamins and the creation of bile.

Approximately 80% of cholesterol in our bodies is synthesized by the liver and a few other organs, the remainder originates from the foods we eat.  The portion of cholesterol derived from diet is transported by the bloodstream in low-density lipoproteins (LDL).

Cholesterol is found in foods containing animal fats such as milk, eggs, red meat, pork, crustaceans, etc.  However, the human body produces all the cholesterol it needs, so avoiding foods that have extra fat and cholesterol can greatly reduce the amount of cholesterol in the body.

The body needs cholesterol and it produces all it needs.  High levels of LDL cholesterol are associated with cardiovascular disease.  On the other hand, HDL can help to remove cholesterol from cells and arteries, which is why it is called the “good” cholesterol.  Keeping HDL and LDL cholesterol in balance is one of the primary goals toward a healthy cardiovascular system.
