The Lipid War: RFK Jr.'s 'Inverted Food Pyramid' and the Seed Oil Conspiracy

The viral 'Hateful Eight' theory names eight seed oils — canola, corn, cottonseed, soy, sunflower, safflower, grapeseed, and rice bran — as industrial products repackaged for human consumption, with some versions of the theory pointing to old high-erucic-acid rapeseed oil's early-20th-century industrial and lubricant uses as supposed proof, even though that history doesn't describe the modern, food-safe canola oil bred specifically for eating in the 1970s. Kennedy has said Americans are being 'unknowingly poisoned' by seed oils and has pushed for a switch to beef tallow, framing it as a stand against industry interests ^[2]. Nutrition scientists reject the poisoning and conspiracy framing outright: no body of evidence shows seed oils are uniquely harmful, and mainstream health organizations have not endorsed the idea that their promotion is a deliberate industry plot ^[2].

The American Heart Association's own published position is the opposite of the 'Hateful Eight' claim — in an article titled "There's no reason to avoid seed oils and plenty of reasons to eat them," the AHA says seed oils like soybean and canola oil are a source of polyunsaturated fat that helps lower LDL cholesterol compared with saturated fat, and supports including them as part of a healthy diet ^[3]. TikTok's carnivore-diet and 'trad-wife' influencers have driven a wave of content cooking exclusively with beef tallow as a marker of 'ancestral' purity, part of the same online current Kennedy has tapped into ^[2]. Reaction to the new pyramid split even among MAHA-aligned voices: podcaster and Stanford neuroscientist Andrew Huberman publicly praised it on X, while nutrition researchers and figures including former FDA commissioner David Kessler and the American Medical Association's Dr. Bobby Mukkamala pushed back on its heavy red-meat and saturated-fat emphasis ^[4].
