This post names no source and no type of evidence — no study, no author, no figure — which is itself worth flagging for a claim this specific (oxidation, cell-membrane disruption, inflammation). Against that, independent literature says the opposite of what's claimed: two controlled-trial meta-analyses (2012, 2017) find no significant effect of linoleic acid — the dominant fatty acid in seed oils — on blood inflammatory markers, and a 2025-2026 Frontiers in Nutrition review concludes most human evidence supports a favorable, not harmful, role for linoleic acid in cardiometabolic risk. The industrial-refining argument has a real kernel — oxidized oil reused repeatedly at high heat can produce unwanted compounds — but that's a problem of repeated high-heat frying, not an intrinsic property of seed oils: the same misused olive oil would cause the same issue.
