For years, I have been explaining here that dietary fats are not a meaningful factor in heart disease (arterial disease). Your cholesterol level most likely doesn't matter either unless you have familial hyperlipidemia or diabetes. I believe those outliers skewed earlier studies.)

The article also says this:
The smaller, more artery-clogging particles are increased not by saturated fat, but by sugary foods and an excess of carbohydrates, Dr. Chowdhury said. “It’s the high carbohydrate or sugary diet that should be the focus of dietary guidelines,” he said. “If anything is driving your low-density lipoproteins in a more adverse way, it’s carbohydrates.”
Once again, it's the carbs that are the problem. Best thing is to deal with that carb addiction.
