Fibra - Fuentes alimenticias

Nombres alternativos

Dieta y fibra; Alimento indigesto; Volumen

Fuentes alimenticias:

Hay dos tipos de fibra: soluble e insoluble.

La primera atrae el agua y la vuelve de consistencia gelatinosa durante la digestión, haciendo que este proceso sea lento. La fibra soluble se encuentra en la avena, la cebada, las nueces, las semillas, las habichuelas, las lentejas, las arvejas y algunas frutas y verduras. Se ha comprobado científicamente que este tipo de fibra reduce el colesterol, lo cual puede ayudar a prevenir una cardiopatía.

La fibra insoluble se encuentra en alimentos como el salvado de trigo, las verduras y los granos integrales. Este tipo de fibra parece acelerar el paso de los alimentos a través del estómago y de los intestinos, y le agrega volumen a las heces.
