Germinated grains are extensively used in weaning and geriatric foods. Germination generally improves the nutrient content and digestibility of foods. The present investigation examined the influence of germination of faba bean, soybean, rice, and wheat on the availability of iron, zinc, calcium, manganese, and copper. Germination increased the availability of iron by>fourfold from faba bean and soybean and by>twofold from rice, whereas such a beneficial influence was not seen in wheat. The availability of zinc from rice and wheat increased to an extent of 80% and 87%, respectively, as a result of germination. However, germination reduced the availability of zinc from faba bean and soybean. Germination increased the availability of calcium from faba bean, soybean, and rice. Germination did increase the availability of manganese from soybean (14.4%) and rice (43%), whereas germination did not exert any influence on availability of copper from rice and wheat; it significantly decreased (12.7% and 14.3%, respectively) the same from faba bean and soybean. Thus, germination could be an appropriate food-based strategy to gain iron and other minerals maximally from food grains. Los granos germinados son muy utilizadas en alimentos de destete y geriatricos. La germinacion generalmente mejora el contenido de nutrientes y la digestibilidad de los alimentos. La presente investigacion examino la influencia de la germinacion de semillas de haba, soja, arroz y trigo sobre la disponibilidad de hierro, zinc, calcio, manganeso y cobre. La germinacion aumento la disponibilidad del hierro por mas de 4 veces a partir de habas de soja y por mas de 2 veces a partir de arroz, mientras que una influencia beneficiosa no se observo en trigo. La disponibilidad de zinc a partir de arroz y trigo aumento en un grado de 80 y 87%, respectivamente, como resultado de la germinacion. Sin embargo, la germinacion redujo la disponibilidad de zinc a partir de habas y soja. La germinacion aumento la disponibilidad de calcio en habas, soja y arroz. La germinacion hizo aumentar la disponibilidad de manganeso a partir de soja (14,4%) y arroz (43%). Mientras que la germinacion no ejercio ninguna influencia sobre la disponibilidad de cobre del arroz y el trigo, que disminuyo significativamente (12,7% y 14,3%), lo mismo en habas y soja. Por lo tanto, la germinacion puede ser un estrategia apropiado basada en el alimento para ganar hierro y otros minerales al maximo de granos alimenticios.
