On his Substack, Chris Masterjohn, PhD, makes a case against statins and explains cholesterol in a way that you won’t hear from most doctors. He writes:
Blood cholesterol levels, along with LDL particle count, ApoB concentration, LDL particle size, LDL pattern, and the ratio of cholesterol between LDL and HDL are all governed centrally by the LDL receptor.
Genetic mutations in LDLR cause familial hypercholesterolemia by lowering LDL receptor expression. One in a million people are born with homozygous mutations, and this can cause heart attacks as young as 18 months old. One in 300 people are born with heterozygous mutations, which shifts heart disease forward from a phenomenon that primarily kills between the age of 60 to 80 to one that primarily kills between the ages of 35 and 60.
The LDL receptor is the main way you bring cholesterol from outside the cell to inside the cell. While the liver only makes about 16% of the body’s cholesterol, it is overwhelmingly responsible for controlling the concentration of cholesterol in the blood by taking it up using the LDL receptor. That cholesterol can then be put to productive use, especially for the synthesis of bile acids to support digestion.
