LDL lipoproteins can cause plaque buildup in the arteries. Though I could see how that can be seen differently than actually carrying cholesterol to the arteries. Same negative effect in my book! I am a little confused on whether the cholesterol actually goes to the arteries, or if it just contributes to the plaque itself. Here's what I found on webmd:

What Is LDL?

Cholesterol isn't all bad. It's an essential fat the cells in your body need.

Some cholesterol comes from the food you eat, and your liver makes some. It can't dissolve in blood, so proteins carry it where it needs to go. These carriers are called "lipoproteins."

LDL is a microscopic blob made up of an outer rim of lipoprotein and a cholesterol center. Its full name is "low-density lipoprotein." It's bad because it becomes part of plaque, the stuff that can clog arteries and make heart attacks and strokes more likely.

Nice work with the PB and olive oil! Those are some great fats! I have pretty great numbers for cholesterol and I eat similarly!
