  "summary": "Olestra is a fat that the body cannot digest, made so that its molecules are too large and too crowded for digestive enzymes to reach. It fries and tastes like fat and contributes no calories. Sold as Olean, it was required in the United States for years to carry a label about digestive effects and reduced absorption of fat-soluble vitamins.",
  "derivation_summary": "Made by attaching six to eight fatty acids to a sucrose molecule instead of the three that glycerol carries in ordinary fat. Products made with it are fortified with vitamins A, D, E and K to offset what it carries out.",
