Preventing high cholesterol levels is important to preventing heart conditions. In order to know how to prevent high cholesterol, it is important to learn more about cholesterol as a whole and be able to tell the difference between good and bad cholesterol. Learning how to exercise properly and have dietary balance is a must in the fight against high cholesterol and heart disease that can cause stroke or heart attacks.
What is cholesterol?
Half of the battle of preventing high cholesterol is knowing what cholesterol is and what you can do to prevent your cholesterol levels from getting out of control.
Cholesterol is a fatty substance, also called a lipid, that is an important part of the cell membrane (outer lining) in animals. It is also circulating through the blood of humans. The cholesterol that is in our blood typically comes from two different sources, either in the food we eat or produced in the liver.
Foods that come from plants contain no cholesterol. The main sources of high cholesterol are dairy products, fish, poultry, and meat. Liver and other organ meats we eat have the highest cholesterol levels compared to other foods. Cholesterol is absorbed into the intestines and forms a type of protein "coat".
What is the difference between good and bad cholesterol?
When we talk about having high cholesterol, we refer to having high levels of "bad cholesterol" or LDL cholesterol. LDL levels are generally associated with heart problems and heart disease. The particular cholesterol type forms itself as hardened proteins on cell and artery walls which causes the formation of a thick substance that can eventually clog the arteries.
HDL cholesterol is known as good cholesterol. HDL cholesterol prevents heart problems by taking the bad cholesterol away from the artery walls and sending it to the liver for proper disposal. High levels of bad cholesterol and low levels of good would create an internal problem because the arteries become clogged and none of the LDL goes to the liver for disposal.
How do we determine high cholesterol?
High cholesterol levels really refers to whether the person has too much LDL cholesterol versus the better-for-your-body HDL cholesterol. By taking the sum of each level, as well as calculating in the intermediate density cholesterol, health practitioners can tell which type of cholesterol outweighs the other. When LDL has a comparatively high level to HDL, doctors diagnose high cholesterol.
