Vitamina A - Fuentes alimenticias

Nombres alternativos

Retinol; Carotenoides

Fuentes alimenticias:

La vitamina A proviene de fuentes animales como los huevos, la carne, la leche, el queso, la crema de leche, el hígado, el riñón y el aceite de hígado de bacalao y de hipogloso. Sin embargo, todas estas fuentes, a excepción de la leche descremada fortificada con vitamina A, tienen un alto contenido de grasa saturada y colesterol.

El retinol es un tipo activo de vitamina A y se encuentra en los hígados de animales, la leche entera y algunos alimentos fortificados.

Las fuentes de betacaroteno son las zanahorias, la calabaza, la batata o camote, el melón, el calabacín, el melón cantalupo, la toronja, el albaricoque, el brócoli, la espinaca y la mayoría de las hortalizas de hoja verde. Cuanto más intenso es el color de la fruta u hortaliza, mayor es el contenido de betacaroteno. Estas fuentes vegetales de betacaroteno no tienen grasa ni colesterol.
