"The intestinal wall controls what particles can pass through, and in the case of sugars, it only allows one at a time. Picture a revolving door; two people holding hands are walking toward the door but must let go of each other to enter the doorway. Sucrose is like two friends, one named glucose and one fructose, holding hands. This link must be broken, so that glucose and fructose can find their specific doorway, go through it and go into the bloodstream."
"For a bit of extra info, aspartame has 0 calories because it can't be broken down and have its energy extracted for use or storage as fat. Your body takes molecules apart, which releases energy. To use the handle analogy, sucrose is like a square box with a bar screwed onto it, and your body uses a screwdriver to take it apart. Aspartame is a ball with a bar nailed onto it. Your body doesn't have a claw hammer to take it apart."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
