摘要：In 1996, each American consumed
an average of 77 pounds
more of commercially grown
vegetables than in 1970, 62 pounds
more grain products, 54 pounds
more fruits, 31 pounds more poultry,
10 gallons more milk lower in fat
than whole milk, 20 pounds less red
meat, 73 fewer eggs, and 17 gallons
less whole milk (fig. 1). In 1994 (the
latest year for which nutrient data
are available), meat, poultry, and
fish contributed nearly a third less
saturated fat to the per capita food
supply than in 1970, and beverage
milk contributed a half less saturated
fat. Similarly, eggs¡¯ contribution
to total dietary cholesterol
declined by a fourth between 1970
and 1994, and beverage milk¡¯s contribution
declined by a half.
