Text 2If 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, Biil 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. Grocery lists, org. The collection, which now numbers more than 500 lists, is strangely addictive. The lists elicit two-fold 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 "Tootie food, kitten chow, bird food stick, toaster scrambles, coffee drinks" Some shoppers organize their lists by aisle; others start with dairy, go to cleaning supplies and then back to dairy before veering off to Home Depot. A few meticulous ones note the price of every item. One shopper had written in large letters on an envelope, simply, "Milk".The thin lines of ink and pencil jutting and looping across crinkled and torn pieces of paper have a purely graphic beauty. One of life’s most banal duties, viewed through the curatorial lens, can somehow seem pregnant with possibility. It can even appear poetic, as in the list that reads "meat, cigs, buns, treats".One thing Keaggy discovered is that Dan Quayle is not alone--few people can spell bananas and bagels, let alone potato. One list calls for "suchi" and "strimp". "Some people pass judgment on the things they buy," Keaggy says. At the end of one list, the shopper wrote "Bud Light" and then "good beer". Another scribbled "good loaf of white bread". Some pass judgment on themselves, like the shopper who wrote "read, stay home or go somewhere, I act like my mom, go to Kentucky, underwear, lemon". People send messages to one another, too. Buried in one list is this statement: "If you buy more rice, I’ll punch you." And plenty of shoppers, like the one with both ice cream and diet pills on the list, reveal their vices. Bill Keaggy collects grocery lists because（）

Text 4According to studies cited by the National Eating Disorders Association, 42 percent of girls in first through third grade want to be thinner, 81 percent of 10-year-olds are a {raid of being fat, and 51 percent of 9- and 10-year-old girls feel better about themselves if they are on a diet.In many ways, this fixation on weight at ever earlier ages comes at an inopportune time physiologically. At a recent Hadassah meeting at the Woodlands Community Temple in White Plains, Dr. Marcie Schneider, the director of adolescent medicine at Greenwich Hospital, and Erica Leon, a registered dietitian, spoke about early adolescence as a time when a little hit of pudginess is necessary for proper growth, and youngsters wrestle constantly with their body image."I can’t tell you how many kids I’ve seen who’ve been on the Atkins diet, or on the South Beach diet," Ms. Leon said, adding that overweight children who try diets can be at risk of developing eating disorders.After the presentation, three mothers from Hartsdale who wanted to help their children avoid such issues spoke about how their young daughters are already beginning to become weight-conscious.Anorexia is a mental illness in which the victim eats barely enough to survive, because her distorted thinking makes her think she is fat. Bulimia, a mental illness in which someone binges on large amounts of food, then purges it through vomiting or the abuse of laxatives, is on the rise, and is surfacing in younger and younger patients, mostly girls, said Judy Scheel, the director of the Center for Eating Disorder Recovery in Mount Kisco.About 90 percent of victims of eating disorders are female, and often the male victims are on teams like wrestling and crew, where they must keep their weight low for competitive reasons. Dr. Scheel believes that where girls claim the eating disorder enables them to be thin, boys typically state their goal is to achieve or maintain a muscular but thin physique. The average onset for bulimia used to be 17, but to see teenagers age 14 and 15 with bulimia is common these days, Dr. Scheel said.Other people believe the disorders have genetic Or chemical components, and many people with eating disorders respond well to anti-depressants, for example.A certain amount of education is necessary to help young people avoid becoming obsessed with their body image. "Teachers need to stay outside of talking about diets," Dr. Scheel said. "It’s like a parent, always talking about their next diet. You have to help a child understand that if you eat healthily and exercise, your body is going to take care of itself."And in relatively homogenous populations, like in some Westchester schools, competition runs high. "So the young people don’t really see how beautiful diversity is," she said, "and they tend to all be competing for kind of the same goals." The studies cited by the National Eating Disorders Association are made among（）
