Key findings

* In 2007-2008 the average energy intake for men was 2,504 kilocalories (kcals) and for women it was 1,771 kcals.
* The average carbohydrate intake was 47.9% of total kilocalories (% kcals) for men and 50.5% kcals for women; average protein intake was 15.9% kcals for men and 15.5% kcals for women; average total fat intake was 33.6% kcals for men and 33.5% kcals for women; and average saturated fat intake was 11.0% kcals for men and 11.1% kcals for women.
* Energy intake appeared relatively stable over the 10-year period from 1999-2008; there were no statistically significant linear increases or decreases in total energy intake.
* There were statistically significant trends in intake of the macronutrients: average carbohydrate intake decreased and average protein intake increased in both men and women.

The Surgeon General’s recent call for renewed efforts to address the high prevalence of obesity in the U.S. adult population highlights the need for better understanding of trends in consumption of energy and the macronutrients protein, carbohydrate, and fat (1). The National Health and Nutrition Examination Survey (NHANES) is the primary national data system that provides information to monitor the nutritional status of the U.S. population. A previous study using NHANES data to report on trends in intake of energy and macronutrients from 1971-1974 through 1999-2000 showed statistically significant increases in intake of energy and carbohydrate, and a decrease in intake of fat in men and women (2). The objectives of this report are to present current estimates of intake of energy and intake of protein, carbohydrate, total fat, and saturated fat, and to evaluate trends in intake of these nutrients over the past decade.
