LACTOFERRIN, CALCIUM, VITAMIN C AND LACTOSE INFLUENCE ON IRON ABSORPTION IN BREASTFED INFANTS

Klju~ne rije~i: apsorpcija `eljeza, deficitarna anemija, laktoferin, prirodna prehrana, ekskluzivno dojenje SA`ETAK. Stru~ne udruge pedijatara u svijetu posljednjih godina isti~u va`nost prirodne prehrane i raznim se mjerama zala`u za njezino unapre|enje. Jedan od razloga takvim nastojanjima jest i pozitivan utjecaj sastavnica maj~ina mlijeka na pobolj{anje apsorpcije `eljeza. U odnosu na druge vrste mlije~ne prehrane djece, `enino mlijeko sadr`i glikoprotein laktoferin, koji svojim biokemijskim osobinama omogu}ava adekvatnu apsorpciju Fe iz humanog mlijeka. Osim laktoferina, za apsorpciju `eljeza iz maj~ina mlijeka, va`an je sadr`aj kalcija, koli~ina vitamina C, kao i koli~ina laktoze. Svi sastojci u `enskom mlijeku, uskla|eni su u svojim koli~inama pojavljivanja, te zadovoljavaju apsorpciju `eljeza iz humanog mlijeka i u ekskluzivno dojene djece do 6 mjeseci `ivota. Djeca hranjena ekskluzivno dojenjem pokazivala su manju u~estalost deficitarnih anemija od djece hranjene drugim vrstama mlije~nih pripravaka. Kravlje mlijeko, u odnosu na ostale vrste mlije~ene prehrane i s obzirom na na~in apsorpcije `eljeza, nije po`eljno u prehrani djece do kraja prve godine `ivota, a svi poku{aji da se sastav adaptiranih mlije~nih pripravaka prilagodi sastavu `eninog mlijeka za sada su jo{ na putu ostvarenja.
