Data collected for the third School Nutrition Dietary Assessment Study (SNDA-III) show the majority of school children in the United States have nutritionally adequate diets, but excessive intakes of saturated fat and sodium.
This report on SNDA-III used Dietary Reference Intakes and the Dietary Guidelines for Americans 2005 to assess the nutritional quality of the diets of U.S. public schoolchildren. Researchers followed Institute of Medicine procedures to estimate the prevalence of inadequate and excessive usual intakes of macronutrients, vitamins, minerals, calcium, potassium, sodium and fiber. Standards used included Estimated Average Requirements (EAR) for most vitamins and minerals and Tolerable Upper Intake Levels (UI) for sodium. Propensity score matching enabled comparison of school meal program participants and nonparticipants.
Data related to the intake of dietary supplements were not available.
