First she talked about a few of the body’s different systems and how they
worked. Then she gave a visual demonstration of the digestive system using a
nylon stocking to represent the colon.With an apron and some latex gloves on, she began cramming the average American diet into the “large intestine.” Hamburgers, fries, a can of Dinty Moore, a jelly donut… even some Coke and a milkshake. Almost immediately the
stocking began to clog up as the food clumped together and stuck to the sides. It
looked like a boa constrictor that had just swallowed an animal three times its
own width. In order to get it to pass through she had to constantly work it and
knead it with her hands.
It wasn’t a pretty picture – enough to scare anyone into giving up fast food
forever. And a lot of people did.
Then she started over with a brand-new, fresh stocking (if only it was that easy,
right?). This time she began dumping apple slices, grapes, pineapple chunks,
carrots, celery and all kinds of other fruits and vegetables down the tube. They all
slid right through without a single hangup.
