Not to mention understanding the different types of LDL (large/puffy vs. small/dense) and testing for it. Main stream health is junk science.
You have zero'd in on something very important ─ what I mentioned as quality of lipid particle ─ for in a metabolically healthy person it's the quality of the LDL against the backdrop of insulin sensitivity that matters, not the quantity (ie, not the particular LDL number). The LPIR score (LipoProtein Insulin Resistance assessment) can be a useful tool in the early identification of insulin resistance and related conditions such as heart disease and type-2 diabetes. Unfortunately much of modern medicine is fixated on the LDL and Total Cholesterol numbers, rather than whether the patient is metabolically healthy, insulin resistant or not, quality of the cholesterol (ie, particle sizes). But there are many doctors, generally younger, that are more aware of these distinctions rather than automatically prescribing statins due to "high" numbers.
There's just so much to expand on when we talk about "modern medicine" being "fixated" on the wrong stuff!
