It is common sense as long as you realize the relationship between cholesterol level and health is curvilinear, not linear.
Too high is bad; apparently too low (in the case of HDL and now LDL) is bad.
Basically you want high HDL and middle-range LDL, not extremely low LDL.
Many of us will never have to worry about having extremely low LDL!!!
When I said “too high is bad” this means total cholesterol==>high or LDL ==> high
Okay....but what if you have small, dense, non buoyant LDL? That’s what I have. Been told it’s hereditary, not good, and the best thing to do is eat healthy and exercise...which I do. VAP Cholesterol tests tell you this.
