Gastrointestinal health. The role of pro- and pre-biotics in standard foods

Abstract

BACKGROUND: Diarrhoea is a common symptom of gastrointestinal illness, ranking among the 20 most frequent reasons for patient encounters in general practice in Australia. Children under 5 years of age are especially vulnerable to bacterial gastroenteritis such as infections with Campylobacter jejuni. Everyday diet, in particular the regular consumption of pro- and pre-biotics, can help with the maintenance of a healthy gastrointestinal system. OBJECTIVE: This article outlines the potential of 'everyday standard' food items such as cheese to promote healthy gastrointestinal microflora and to prevent gastrointestinal illness such as diarrhoea. DISCUSSION: Some common food items such as yoghurt, sauerkraut, garlic and cheese contain probiotics in the form of live lactic acid bacteria, and/or prebiotics in the form of fructans, a dietary fibre. Cheese contains both probiotic bacteria and the prebiotic dietary fibre inulin. The regular consumption of cheese has been associated with a reduction in the risk of Campylobacter enteritis.
