Aspectos nutricionales de los elementos minerales y del agua

Abstract

En los seres vivos, además de los elementos químicos que constituyen la materia orgánica (carbono, oxígeno, hidrógeno y nitrógeno), existen otros que forman parte de la composición de aquellos o de la materia inorgánica, aunque en pequeñas cantidades. A tales elementos se les denomina elementos minerales, y sólo se pueden obtener a través de la dieta. Los elementos minerales se clasifican atendiendo a las cantidades en las que son necesarias diariamente para los humanos y en las cantidades en las que aparecen en el cuerpo. La figura 1 recoge una propuesta para su clasificación atendiendo a sus necesidades, dividiéndolos en macrominerales (más de 100 mg), microminerales u oligoelementos (menos de 100 mg), elementos traza (generalmente entre 1µg y 1 mg) y elementos ultratraza (cuyas cantidades exactas y funciones suelen ser desconocidas). Hay que decir que esta clasificación ni refleja la importancia nutricional de los elementos, ya que la deficiencia de un elemento que se requiere en ínfimas cantidades puede ser tanto o más perjudicial que la causada por otro elemento que se requiere en grandes cantidades, ni está aceptada por toda la comunidad científica, pues hoy en día todavía se dan diferentes clasificaciones en función de distintos autores.
