Farmers in the United States produce almost 4,000 calories per day per person. This is more than twice the average person's daily caloric need, and about 700 more calories per day than were produced in the 1980s. Out of that, the average American eats about 2,750 calories a day. Some of the rest is fed to animals or exported, but about a fourth of edible food is wasted.
