As we’ve seen on the homepage of this site, a prebiotic is kind of like a bacterial fertilizer targeting the good bacteria in our guts.  In order to be considered a prebiotic, a substance must exhibit three properties:

  1. The fibre must be resistant to human digestion.  The prebiotic needs to feed the good bacteria, not the human.
  2. The fibre needs to be fermentable by the good bacteria in your gut.
  3. The fibre should selectively stimulate colonies of good bacteria in your gut.

Prebiotics are found naturally in the plant food that we eat.
