Legal Action Against the Food Industry

In a March 2026 interview, Dr. Robert Lustig said: “We’re suing the food industry in various venues.” He has offered no public detail on which suits or venues he is involved in, and this research found no court filings bearing his name — so his personal role in any food-industry litigation remains unverified beyond his own statement.

Related context: on December 2, 2025, San Francisco City Attorney David Chiu filed what was described as a first-of-its-kind suit against ten major ultra-processed-food manufacturers — Kraft Heinz, PepsiCo, Coca-Cola, Mars, Mondelez, Nestlé USA, General Mills, Kellogg, Post, and ConAgra — under California’s Unfair Competition Law, alleging deceptive marketing of addictive foods. That litigation runs squarely in the line of Lustig’s advocacy, though no direct link between Lustig and the Chiu suit has been established.
