Data are presented as mean ± SD or median (IQR). AI = Adequate Intake; DRI = Dietary Reference Intakes; EAR = Estimated Average Requirement; UL = Tolerable Upper Intake Level; RDA = Recommended Dietary Allowance. 1 Men and women, respectively. 2 p value by one-sample t-test or Wilcoxon signed-rank test to analyse differences between mean intake and DRI.
