The oleic acid group, the group that didn’t see an increase of metabolites, was given high-oleic sunflower oil. I brought that up because it’s a chemically extracted seed oil, and one of the most common seed oils. “Seed oil” is not a significant distinction of fatty acid composition. Seed oils have varying linoleic acid composition (sesame oil for example is quite balanced, high-oleic sunflower is close to olive oil ratios). The study you linked showed an increase in oxidation metabolites for the LA group. But as far as I understand, those metabolites don’t demonstrate damage to anything or an impact on mortality. That’s why I linked to a study that measures oxidative DNA damage via 8-oxo-dG in blood, which found no impact from increased linoleic acid consumption. So the theory that linoleic acid is dangerous because of damage via oxidative stress isn’t clearly supported by current literature.
