Fibra insoluble vs. fibra soluble

Información

Existen dos tipos diferentes de fibra: soluble e insoluble y ambos son importantes para la salud, la digestión y la prevención de enfermedades.

  • La fibra soluble atrae el agua y se convierte en gel durante la digestión. Esto lentifica el proceso digestivo. Este tipo de fibra se encuentra en el salvado de avena, la cebada, las nueces, las semillas, los fríjoles, las lentejas, las arvejas y algunas frutas y verduras. También se encuentra en el psilio, un suplemento común de fibra. Algunos tipos de fibra soluble pueden ayudar a disminuir el colesterol, pero el efecto sobre la cardiopatía no se conoce.
  • La fibra insoluble se encuentra en alimentos como el salvado de trigo, las verduras y los granos integrales. Este tipo de fibra le aporta volumen a las heces y parece ayudar a que los alimentos pasen más rápidamente a través del estómago y los intestinos.
