Extract: The purpose of the study was to evaluate the calorie, protein, and mineral content of school lunch meal pattern menus served at a public school in central North Dakota as set forth in the Child Nutrition Regulations. Calcium, phosphorus, iron, magnesium, sodium, potassium, and zinc contents of school lunch meal patterns were compared to one-third the recommended dietary allowances (RDAs), and the interrelationship between calorie, protein, and mineral content of the menus was determined. The caloric, protein, and mineral levels in the menus were calculated from food composition tables for the standard menus for 19 days. On some days, optional foods were available to the students. Observations by the researchers was used to determine amounts selected by the students and nutrient content was calculated from food composition tables. Results indicated calorie and magnesium means were below the nutritional goals, while means for calcium, phosphorus, iron, sodium, potassium, and zinc met or exceeded one-third the RDAs. Nutrient density values indicated high nutrient foods were served. Statistically significant differences (P less than .01) between the calorie, protein, and mineral contents and one-third of the RDAs were observed for the standard menus. Similar results were reported for the optional menus with the exception of magnesium, which was found not to differ significantly from one-third of the RDA. Statistically significant correlation between a majority of the mineral values and calorie and protein values were found.(author)
