Trying to get Americans to eat a healthy diet is a frustrating business. Even the best-designed public-health campaigns cannot seem to compete with the tempting flavors of the snack-food and fast-food industries and their fat-and sugar-laden products. The results are apparent on a walk down any American street—more than 60% of Americans are overweight, and a full quarter of them are overweight to the point of obesity.
Now, health advocates say, an ill-conceived redesign-has taken one of the more successful public-health campaigns—the Food Guide Pyramid—and rendered it confusing to the point of uselessness. Some of these critics worry that America's Department of Agriculture caved to pressure from parts of the food industry anxious to protect theft products.
The Food Guide Pyramid was a graphic which emphasizes that a healthy diet is built on a base of gains, vegetables and fruits, followed by ever-decreasing amounts of dairy products, meat, sweets and oils. The agriculture department launched the pyramid in 1992 to replace its previous program, which was centered on the idea of four basic food groups. The "Basic Four" campaign showed a plate divided into quarters, and seemed to imply that meat and dairy products should make up haft of a healthy diet, with grains, fruits and vegetables making up the other half. It was replaced only over the strenuous objections of the meat and dairy industries.
The old pyramid was undoubtedly imperfect. It failed to distinguish between a doughnut and a whole-grain roll, or a hamburger and a skinless chicken breast, and it did not make clear exactly how much of each foodstuff to eat. It did, however, manage to convey the basic idea of proper proportions in an easily understandable way. The new pyramid, called "My Pyramid", abandons the effort to provide this information. Instead, it has been simplified to a mere logo. The food groups are replaced with unlabelled, multi-colored vertical stripes which, in some versions, rise out of a cartoon jumble of foods that look like the aftermath of a riot at a grocery store. Anyone who wants to see how this translates into a healthy diet is invited to go to a website, put in their age, sex and activity level, and get a custom-designed pyramid, complete with healthy food choices and suggested portion sizes. This is free for those who are motivated, but might prove too much effort for those who most need such information.
Admittedly, the designers of the new pyramid had a tough job to do. They were supposed to condense the advice in the 84-page United States' Dietary Guidelines into a simple, meaningful graphic suitable for printing on the back of a cereal box. And they had to do this in the face of pressure from dozens of special interest groups—from the country's Potato Board, which thought potatoes would look nice in the picture, to the Almond Board of California, which felt the same way about almonds. Even the National Watermelon Promotion Board and the California Avocado Commission were eager to see their products recognized.
Nevertheless, many health advocates believe the new graphic is a missed opportunity. Although officials insist industry pressure had nothing to do with the eventual design, some critics suspect that political influence was at work. On the other hand, it is not clear how much good even the best graphic could do. Surveys found that 80% of Americans recognized the old Food Guide Pyramid—a big success in the world of public-health campaigns. Yet only 16% followed its advice.
Trying to get Americans to eat a healthy diet is a frustrating business can be easily proved by the fact that
A．public-health campaigns cannot compete with tempting flavors.
B．snack-food and fast-food industries are flourishing in the US.
C．most food in America are profoundly rich in fat and sugar.
D．fat people account for a large proportion of American population.
The history of ice cream is amystery. No one knows exactly how and when people began to eat it. There is onestory that the Roman emperor Nero (A.D. 37—68) sent slaves to the mountains tobring back snow. The snow was served to him sweetened with honey and fruit pulp.Marco Polo (1254—1324) tasted flavored ices, too, during his famous travels inthe Far East. He brought the recipes back toItaly.
Recipesfor ices spread fromItalyto the rest of Europe in the 1500’s. The chefs of kings constantly experimentedwith new combinations to please their masters, and at some point cream andbutter were added to the recipes for ice. The new dish was called cream ice.Cream ice, molded into amusing shapes, began to be served on the tables ofkings across Europe. Louis XIV (1638—1715)surprised his court with a dessert of eggs in cups of silver and gilt. Theeggs, of course, were really cream ice.
Graduallycream ice took the name it has today. One of the earliest advertisements forice cream was put in a New Yorkpaper in 1786. The ad announced that “Ladies and gentlemen may be supplied withice- cream every day at the City Tavern by their humble servant, Joseph Crowe.”But ice cream was still not an everyday event. It was usually presented infancy shapes at the end of dinner parties. Policy Madison (1768—1849) was famous for herimaginative dinners, and she was the first to serve ice cream at the WhiteHouse. When her guests came into the dining room, they found a table coveredwith delicious dishes, and in the center of the table, a huge mound of pink icecream on a silver platter.
Icecream was such a delicacy because it was so hard to make. At first it wasbeaten and then shaken by hand in a pan of salt and ice until it became firm. Afreezer that was cranked by hand was developed around 1846. Making ice creamwas still a chore, but cranking the freezer was much easier and faster thanshaking the mixture in a pan.
“Icecream socials” became a popular way to entertain friends. Everyone helped turnthe crank of the freezer, and homemade peach or strawberry ice cream was thereward. The development of the continuous freezer in the 1920’smade the manufacture of ice cream very quick and economical. It soon was easierto buy packaged ice cream than to make it at home. Eskimo pies and popsiclesbegan to be sold at the same time.
Possiblyice cream cones began with the World’s Fair in 1893. Vendors there sold FriedIce Cream. The ice cream was covered with a fritter batter and then quicklydipped in very hot lard or olive oil. Putting the ice cream in an alreadyprepared cone was the next step. Today there are many novelty products, fromfrozen drumsticks to ice cream pies.
