Can you point to some evidence that increased saturated fat consumption does not increase LDL? Or that there is no link between serum LDL levels and plaque build up? Or are you making a different claim?
Dr Michael Eades is a good gateway toif you're interested. He wrote a book a while ago now titled Protein Power [1], I think he is working on an update/sequel as well.
At the high level, my basic claim is that the idea that dietary saturated fat directly leads to heart attack is incorrect. The history of this claim dates back to President Eisenhower. After having a heart attack while in office he wanted to tell the public how he could avoid the same fate. Researchers cut corners to meet political targets, ignoring data that disproved their hypothesis and claimed that plaque found in cadaver arteries was made of saturated fats and that it got there due to the person's diet.
The claims weren't backed up by the studies used and we were told that this was now a known fact when it wasn't. We've spent many decades since avoiding saturated fats in favor of unsaturated fats, which are highly oxidative and have concerning side effects when run through the Krebs Cycle.
Dr Eades also has a few interesting talks on the subject when he walks through the Krebs Cycle and the difference of saturated and unsaturated fats in case that's helpful. I think [2] is one I watch years ago, though he has other similar talks on YouTube as well.
