Robert Lustig on Fructose: warns against

Dr. Robert Lustig warns specifically against fructose, the component of added sugars he says is metabolically dangerous. He argues that fructose is metabolized in the liver much like alcohol — driving fat production, insulin resistance, and fatty liver disease. This is Lustig’s stated position; the dossier notes active scientific pushback, including controlled feeding trials whose results an interview host challenged him on in September 2026.

His stated reasoning underlies his signature policy proposal: removing fructose from the FDA’s “Generally Recognized As Safe” (GRAS) list, which he says would force industry to prove its safety and drive down its use.
