CHANGE: Americans Are Finally Eating Less. “Calories consumed daily by the typical American adult, which peaked around 2003, are in the midst of their first sustained decline since federal statistics began to track the subject, more than 40 years ago. The number of calories that the average American child takes in daily has fallen even more — by at least 9 percent.”

Well, you know, calorie consumption probably fell during the Great Depression, too. But people also tend to eat less as they age, and the population is getting older; I can’t tell if the study addressed that.
