True, I consider those things to be established to this day. Regarding cholesterol and dietary levels to serum levels, it's curvilinear. If you have a low baseline, dietary input has a strong impact on serum output. If you are eating a standard American diet that has a relatively high baseline cholesterol level, the relationship weakens to being statistically insignificant. And sure, you can get fat without eating fat, and you can create high fat diets that don't increase visible body fat, but those aren't healthy diets.
