Robert Lustig on Extra Virgin Olive Oil: recommends

Dr. Robert Lustig recommends extra virgin olive oil — with the caveat not to overheat it. He says the oil’s oleic acid supports liver function, but that heating it beyond its smoke point can damage its fats.

His stated reasoning places olive oil within his “protect the liver” precept of the Metabolic Matrix: the oil is beneficial, he says, when its fats are not degraded by high heat. The guidance comes from his September 2026 practical dietary interview covering his grocery rules.
