Probiotics, Prebiotics

A Catalyst article about the human gut and the many microbes it hosts, mainly bacteria. Probiotics are live bacterial ingredients or supplements designed to multiply in the colon and have an impact on health. A prebiotic is a carbohydrate that is not digestible by humans. The article examines the role they play, and looks at ways to encourage 'good bacteria' through diet.

This article is from Catalyst: Secondary Science Review 2008, Volume 18, Issue 4.
