Fortificación de alimentos con hierro y zinc: pros y contras desde un punto de vista alimenticio y nutricional
Palavras-chave:
hierro, zinc, fortificación, alimentoResumo
La deficiencia nutricional de ciertos minerales como el hierro y zinc afectan a la población a escala mundial con graves efectos sobre la salud dependiendo fundamentalmente del grado de incidencia y de la magnitud de la deficiencia. La fortificación de alimentos ha resultado ser la estrategia más efectiva para corregir esta situación con inconvenientes que radican no solamente en la elección del alimento a utilizar como transporte para dichos nutrientes sino también en la correcta elección del compuesto a utilizar como fortificante ya que en general aquellos compuestos que poseen una adecuada biodisponibilidad presentan cambios en las características sensoriales de los alimentos fortificados poco aceptables para su consumo. Los compuestos inertes, que poseen propiedades optimas desde del punto de vista tecnológico poseen una baja absorción que los convierte en compuestos nutricionalmente poco útiles. En este trabajo se discute con mayor detalle estos aspectos con el fin de llegar a un entendimiento más profundo de la problemática antes mencionada.
