Dr. Robert Lustig is an endocrinologist and professor of pediatrics in the Division of Endocrinology at the University of California-San Francisco. In this video, he sits down with CrossFit’s Rory McKernan to explain sugar’s toxicity, outline the stakes of sugar consumption and offer suggestions for addressing the ongoing sugar crisis.
“Sugar is toxic,” Lustig explains. “It proffers a set of biochemical alterations that are detrimental to human health—unrelated to its calories.”
In this way, Lustig says, sugar “is very much like alcohol,” and chronic metabolic diseases associated with alcohol are becoming prevalent in children with high-sugar diets.
