Seed oils didn't suddenly change what they are; the narrative changed — in studies that hold calories constant, swapping saturated fat for polyunsaturated fat (seed oils) shows neutral-to-better results for LDL, cardiovascular risk, insulin sensitivity, and liver fat.

This post cites isocaloric substitution studies (saturated fat swapped for polyunsaturated) rather than raw comparisons, which is the methodologically sound way to judge a fat type's effect — and the conclusions match independent literature well: a meta-analysis of 30 cohort studies across 13 countries (Frontiers in Nutrition 2025-2026) links higher circulating linoleic acid to lower, not higher, cardiovascular risk; two dedicated controlled-trial meta-analyses (Journal of the Academy of Nutrition and Dietetics 2012, 15 trials; Food & Function 2017, 30 trials, 1,377 subjects) find no significant effect of linoleic acid on blood inflammatory markers (CRP, IL-6, TNF-α). The post's central point — that anti-seed-oil panic replaced anti-carb panic without better evidence behind it — is an honest, well-sourced summary of where the science actually stands, running counter to the dominant social-media narrative.
