LDL only matters is the particle size is small. My vldl is very low. My triglycerides were 30 on my last blood test. My blood pressure in 110/70 and I can do high intensity exercise comfortably fasted with a blood sugar of 75. I agree with you on fiber and probably in many diet things, but grass fed ruminants, fatty fish, eggs, butter improve that diet. Saturated fat is good for you in normal "as it comes in natural whole foods/long history of preparation" forms.
