摘要：Whether eating out or buying carry-out, Americans are consuming more and more of their calories from full-service and fast-food restaurant fare. The share of daily caloric intake from food purchased and/or eaten away from home increased from 18 percent to 32 percent between the late 1970s and the middle 1990s, and the away-from-home market grew to account for about half of total food expenditures in 2004, up from 34 percent in 1974. Analysis of a survey of U.S. consumers indicates that respondents want convenience and an enjoyable dining experience, but the desire for health also plays a role as does diet-health knowledge.
