摘要：America¡¯s appetite, like its population,
is always changing.
Foods once favored are now rarely
eaten. Foods once only dreamed
about are a reality. Dining out, once
thought to be a luxury, is now common.
The Nation¡¯s population is
wealthier, older, more educated,
and more ethnically diverse than
in the past. And these demographic
changes are likely to become more
pronounced in the next 20 years.
Consumers will continue to demand
new food products, new packaging,
more convenience, new delivery
systems, and safer and more nutritious
foods. Consequently, USDA¡¯s
Economic Research Service (ERS)
has undertaken an extensive effort
to project how population growth,
an aging population, ethnic diversity,
other demographic trends, and
income growth will affect future
food choices and how the food system
will respond to such changes.
