Prebiotics

Prebiotics are a type of dietary fiber that act as food for probiotics, the beneficial bacteria in your gut. They are non-digestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, thus improving host health.

Definition[edit | edit source]

The concept of prebiotics was first introduced in 1995 by Gibson and Roberfroid. They defined prebiotics as "non-digestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, thus improving host health". This definition was later updated to "a selectively fermented ingredient that allows specific changes, both in the composition and/or activity in the gastrointestinal microflora that confers benefits upon host well-being and health".
