NRV, Nutrient Reference Value; ACAES, Australian Child and Adolescent Eating Survey; RDI, Recommended Dietary Intake; AI, Adequate Intake; IQR, inter-quartile range; eq, equivalent. The median intake of niacin is above the upper limit of 20 mg/day [40]. § The median intake of vitamin A is above the upper limit of 1700 μg/day if the total vitamin A source was from retinol, however the vitamin A (retinol equivalents) estimated intake in the sample population includes β-carotene which is not known to result toxicity [40]. ∥ The median intake of magnesium is above the upper limit of 350 mg/day [40]. A median calcium intake of 1270 mg does not meet the RDI for children aged 12 to 13 years and children aged nine to 11 years who are growing at a greater rate than average. The RDI for these groups is 1300 mg [40].
