The discussion critically examines common health concerns about the industrial processing of seed oils, specifically the use of the solvent hexane and high heat.
It argues that residual hexane levels in commercially available oils are negligible (0.05-0.5 ppm), do not bioaccumulate, and pose no realistic health risk via ingestion, requiring an impossible amount of consumption to cause even mild effects.
The risk of oil oxidation during processing is also presented as minimal, as the temperatures and duration are insufficient to cause significant degradation compared to high-heat cooking.
The conversation pivots to suggest that the more significant health question may be the dramatic historical increase in dietary linoleic acid (from <3% to ~10% of food availability) rather than processing contaminants.
