All micronutrient intakes are adjusted for within-subject and between subject variations by the National Research Council (NRC) method. † Derived from ANOVA. Superscript letters denote significant differences (p < 0.05) of mean values between age groups after post hoc multiple comparisons using the Bonferroni rule. Figures sharing the same superscript letters differ significantly from each other: a 9–10 years old vs. 11–13 years old; b 9–10 years old vs. 40–60 years old; c 11–13 years old vs. 40–60 years old.
