Fibra

Nombres alternativos:

Dieta y fibra; Residuo; Volumen

Fuentes alimenticias:

Hay dos tipos de fibra: soluble e insoluble. La primera atrapa el agua y la vuelve de consistencia gelatinosa durante la digestión, haciendo que este proceso sea lento. La fibra soluble se puede encontrar en la avena, la cebada, las nueces, las semillas, las legumbres, 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 la enfermedad cardíaca.

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