Short excerpt of a YouTube video (uploaded by Dr. Ron Najafi) in which Robert Lustig argues that soluble and insoluble fiber form a gel-like lattice in the intestine that blocks transport of glucose, fructose, sucrose and simple starches from the lumen into the portal vein so the liver does not 'see' them, meaning eaten sugars may not be metabolized. He contrasts this with focusing on calories ('what passes your lips') and states his intent to 'kill the calorie' as a useful unit of measure.
