Short excerpt from a YouTube video (speaker: Robert Lustig) summarizing a 2008 study comparing post‑consumption glucose excursions after eating a whole apple, applesauce, and apple juice. The speaker reports that whole apple produces little glucose response, apple juice produces a large spike, and applesauce behaves more like juice—implying that destroying fiber removes its protective effect.
