When the inner lining of your arteries gets damaged, bad cholesterol (LDL) slips in and gets oxidized, which tricks your body into sending in immune cells that create fatty buildup—leading to clogged arteries.

Assessment Explanation
The claim describes a well-established biological pathway in atherosclerosis supported by decades of histological, biochemical, and animal studies. However, the use of deterministic verbs like 'allows' and 'triggers' oversimplifies a complex, multifactorial process. While endothelial dysfunction, LDL infiltration, oxidation, and inflammation are key steps, they are not always linear or sufficient alone. The claim should reflect probabilistic causality given individual variability and confounding factors.
More Accurate Statement
“Endothelial damage is associated with increased infiltration of apoB-containing LDL particles into the arterial wall, where oxidative stress often promotes inflammatory immune responses that contribute to the progression of atherosclerotic plaque.”

Evidence from Studies

This study found that people with a certain version of the ApoB gene have more bad cholesterol, more body stress, and more inflammation — all of which are the exact things that cause artery clogs, just like the claim says.
This study shows that when a harmful cholesterol particle (Lp(a)) gets oxidized, it damages blood vessel lining and causes swelling — but EPA stops that oxidation and reduces the damage. This supports the idea that oxidized cholesterol particles trigger artery plaque buildup.
