Biochemist William Lands argued from the 1980s onward that the massive rise in dietary linoleic acid (the dominant omega-6 fat in soybean, corn, and sunflower oils) is a major driver of chronic disease, via competitive enzyme dynamics between n-6 and n-3 fatty acids. He proposed an upper safe limit of roughly 2% of energy. This idea underpins the popular "seed oils are bad" movement.

Mainstream nutrition science disagrees. The AHA recommends 5-10% of energy from omega-6 PUFAs. Meta-analyses of 150+ cohorts find higher omega-6 associated with lower CVD and mortality risk. Only a small group of researchers (Ramsden, Hibbeln, Simopoulos) support aspects of Lands' position, and no RCT testing LA reduction against hard clinical endpoints has been conducted.

Resolution criteria:

Resolves YES if, before January 1, 2050, at least two of the following bodies have published official guidelines recommending that linoleic acid (or total omega-6 PUFA) intake for the general healthy adult population be limited to at most 4% of total energy: AHA, WHO, EFSA, UK SACN, or US DGAC.

Must apply to the general population, not disease subgroups. Statements merely calling for research do not count. The 4% threshold represents a meaningful shift from current guidance while being more generous than Lands' proposed limit.

Resolves NO otherwise.
