Zinc en la dieta - Food Sources

Fuentes alimenticias:

Los alimentos ricos en proteínas contienen grandes cantidades de zinc. Las carnes de res, cerdo y cordero contienen mayor cantidad de zinc que el pescado. La carne oscura de un pollo contiene más cantidad de zinc que la carne blanca.

Otras fuentes buenas de zinc son las nueces, los granos enteros, las legumbres y la levadura.

Las frutas y las verduras no son buenas fuentes, porque el zinc en las proteínas vegetales no está tan disponible para el consumo humano como el zinc de las proteínas animales. Por lo tanto, las dietas bajas en proteínas y las dietas vegetarianas tienden a ser bajas en zinc.

El zinc está en la mayoría de los multivitamínicos y suplementos minerales. Estos suplementos pueden contener gluconato, sulfato o acetato de zinc, pero no está claro si una forma es mejor que las otras.

El zinc también se encuentra en algunos medicamentos de venta libre, como pastillas, aerosoles nasales y geles nasales para resfriados.
