Topics Covered

• The human large intestine is an intensively colonised area containing bacteria that are health promoting, as well as pathogenic
• This has led to functional food developments that fortify the former at the expense of the latter
• Probiotics have a long history of use in humans as live microbial feed additions
• In contrast, a prebiotic is a non digestible food ingredient that beneficially affects the host by targeting indigenous components thought to be positive
• Dietary carbohydrates, such as fibres are candidate prebiotics but most promise has been realised with oligosaccharides
• As prebiotics exploit non-viable food ingredients, their applicability in diets is wide ranging
• As gastrointestinal disorders are prevalent in terms of human health, both probiotics and prebiotics serve an important role in the prophylactic management of various acute and chronic gut derived conditions
• Examples include protection from gastroenteritis and some inflammatory conditions
