[单项选择]If you are what you eat, then you are also what you buy to eat. And mostly what people buy is scrawled onto a grocery list, those ethereal scraps of paper that record the shorthand of where we shop and how we feed ourselves. Most grocery lists end up in the garbage. But if you live in St. Louis, they might have a half-life you never imagined, as a cultural document, posted on the Internet.
For the past decade, Bill Keaggy, 33, the features photo editor at The St. Louis Post-Dispatch, has been collecting grocery lists and since 1999 has been posting them online at www.grocerylists.org.

The lists elicit twofold curiosity — about the kind of meal the person was planning and the kind of person who would make such a meal. What was the shopper with vodka, lighters, milk and ice cream on his list planning to do with them In what order would they be consumed Was it a he or a she Who had written "
A. Buying what it is scrawled on the paper.

Most people get the insulin they need from the pancreas; a large organ near the stomach. The pancreas makes insulin; insulin brings glucose into the cells; and the body gets the energy it needs. When a person has Type 1 diabetes, it is because the pancreas is not making insulin. So someone could be eating lots of food and getting all the glucose he needs, but without insulin, there is no way for the body to use the glucose for energy. (47) .
