What is the calorie intake for the average American?
United Nations FAO says the average American consumes
3770 calories for 2001-2003.
This number is much greater than many other sources, for example
the American Cancer Society, which lists it (as of 2000) at
2618 for men and 1877 for women.
The reason the United Nations FAO number is higher is because it
includes not just the calories Americans are eating but also the
calories wasted to "spoilage, plate waste, and cooking". See the
USDA Agriculture Factbook.
