We all want to live long, happy and healthy lives – and taking care of our hearts is an essential part of good health and longevity. In this blog I want to tell you a bit about cholesterol and how this complex substance relates to heart disease. In an upcoming blog we’ll look at how to prevent the build-up of the wrong kinds of cholesterol so that we can maintain or restore good heart health.

There was a time when doctors thought of cholesterol as a single compound. We now know that cholesterol actually comes in a wide variety of sizes and shapes, and the names we give to these types are based on their density. The lightest and most buoyant cholesterol is now classed as “very low density lipoprotein” or VLDL. For a variety of reasons, VLDL is the most problematic form of cholesterol you can have in your bloodstream. The second common form of cholesterol is abbreviated “LDL,” which stands for low-density lipoprotein. This form of cholesterol is the most plentiful in most human beings. LDL poses a problem for us because it is easily oxidized into a form which triggers inflammatory reactions within the bloodstream – and as we’ll see below, that is a critical step in developing plaque deposits. Two more common forms of cholesterol are called intermediate density lipoprotein, or IDL, and high-density lipoprotein or HDL.
