Interesting article, Brooks.
Here is a new concept for me in the following quote about the HDL types (actually they are just different phases of the same molecule, it would seem -- just like for the various LDL types):
"It has been shown that high levels of HDL cholesterol are
inversely related to coronary artery disease risk. However,
what people do not know is that there are different subtypes
of HDl (sic), including HDL-2 and HDL-3. HDL-3 is produced
by the liver and intestines and is responsible for scooping up
free cholesterol from the blood vessel walls. The cholesterol
carried by HDL-3 is chemically modified, forming a larger-
sized subtype, known as HDL-2, or “mature HDL.â€Â
