I wonder how much of medicine is driven by drugs. For example, why did they decide that LDL cholesterol is the main marker for heart disease, rather than triglycerides or insulin? After all, triglycerides and insulin are better markers of heart disease risk.
The reason? Probably because LDL cholesterol is "targetable"--there's a drug (statins) that will lower it. So it matters less that LDL is a good marker, and more that it's a number we can change with a drug. And of course, make money in the process. If there were a drug that lowered triglycerides really well, I suspect mainstream medicine would focus more on triglycerides.
(Incidentally, the best way to lower triglycerides and insulin is to control consumption of refined carbohydrates.)
