Trends in Dietary Intake among American
Caloric intake (kcal) 1,983 1,975 2,199
% calories from fat 36.4 36.3 34.1
In the past two decades, the average calorie intake has increased by about 10%. This is both a cause and a consequence of the increasing prevalence of obesity in our country. On a positive note, the percentage of fat in the diet has come down as people have become more aware of the risks of high fat diets. (source: Ernst et al. 1997, Am. J. Clin Nutr.)
