Interventional trials suggest linoleic acid has a worse impact on health compared to more saturated fat.

“this is one of the reasons that epidemiology can be so confusing if everyone in the in the population has massive amounts of linoleic acid even the people eating the least linoleic acid are probably eating too much linoleic acid so you're not going to see a signal that linoleic acid is necessarily causing disease when you do an epidemiology observational study in the u.s population in 2010 or 2020 because everybody is eating five to ten times more than they should be so even the lowest group is probably at a toxic level and that's very scary that's the problem with epidemiology”
