Abstract: | The Spanish market offers a significant number of folic acid (FA) voluntarily fortified foods. We analysed FA and (6S)-5-methyltetrahydrofolic acid ((6S)-5-CH3-H4PteGlu) content in ready-to-eat cereals (RTEC) (n = 68) and cow’s milk (n = 25) by a previously validated affinity chromatography–HPLC method. Contribution to potential FA intakes for children aged 2–13 years, was assessed using food consumption data from a representative nationwide study, folate Recommended Dietary Intakes (RDI), and Upper Levels (UL). Results showed that at all food fortification levels obtained, fortified products provided more than tenfold FA than (6S)-5-CH3-H4PteGlu. For RTEC, the high fortification level provided 6–21%, per serving, of RDI and ?32% of ULs at 90th percentile of RTEC consumption (P90). Milk products fortified at the higher level reached on average 54–136% of RDI per serving and only exceeded UL at P90 of milk consumption in children aged 2–5 years. |
