Nutritional Profile of Kuwaiti Composite Dishes: Minerals and Vitamins

Twenty-two Kuwaiti composite meat, fish, chicken, cereal, and sweet dishes were analyzed for 14 mineral elements and 11 vitamins. Except for very few high values in the levels of certain minerals and vitamins, the results indicated the following concentrations (mg/100 g): sodium, 2–910; potassium, 21–620; calcium, 13–520; phosphorus, 17–360; magnesium, 11–103; iron, 0.2–2.9; copper, 0.05–0.40; manganese, 0.10–2.70; boron, <0.05–0.74; chromium, <0.05–0.09; aluminum, <0.05–1.80; iodine, <0.01–0.28; and selenium (μg/100 g), 0.76–63.00. The concentrations of the vitamins were: vitamin A traces, 207 retinol equivalent/100 g; vitamin D traces, 156 I.U.; vitamin E traces, 2.92 mg α-tocopherol/100 g; vitamin C traces, 6.3 mg/100 g; thiamin, 0.008–0.384 mg/100 g; riboflavin, 0.023–0.855 mg/100 g; pyridoxine, 0.024–0.206 mg/100 g; niacin, 0.11–5.34 mg/100 g; pantothenic acid, 0.113–1.36; biotin, 0.001–0.009 mg/100 g; folacin T, 62 μg/100 g; and vitamin B12 T, 1.32 μg/100 g. These results are discussed in relation to the Recommended Dietary Allowances for the U.S. population set by the Food and Nutrition Board, National Research Council, National Academy of Sciences.
