Food fights

摘要

"ENJOY your food, but eat less." "Avoid oversized portions." "Make half your plate fruits and vegetables." This is not advice from your mother, but carefully crafted, consumer-tested wisdom from the United States Department of Agriculture (usda). Earlier this month the usda and Michelle Obama, the first lady, unveiled these messages and a new dietary icon. "MyPlate" shows a table setting with portions of fruit, vegetables, grains and protein, with a small side-order of dairy. The image is supposed to represent a healthy diet. For many Americans it might as well be a meal from Mars.
