Dr. Peter Attia, M.D. has written an extensive blog post about Cholesterol covering how it is absorbed, transported through the body, and ultimately why it builds up in our arterial walls. It is a nine part blog and there is a podcast series that goes along with it with Dr. Tom Dayspring, M.D. It is not an easy read but it if you stick with it you’ll better understand how to get your cholesterol under control and how to better measure your levels. The bottom line is your standard cholesterol test is useless, you have to have a lipoprotein analysis using NMR spectroscopy. This test will tell you the number of LDL-P (apoB) in your blood and it is the best predictor of cardiac events https://peterattiamd.com/the-straight-dope-on-cholesterol-part-ix/.
