a Although adequate intake values are provided by the Institute of Medicine for infants (0–12 months) and recommended dietary allowances for children (1–3 years) [143], there are scarce data regarding micronutrient deficiencies in this age groups in industrialized countries and these ages have therefore not been included in this table; b values differ in pregnancy and lactation. F, females; M, males. Reported micronutrient intakes in bold are below the recommended dietary allowances.
