简要总结
To investigate the potential of B-GOS to beneficially influence the wellbeing and ageing in healthy adults (52-65 years old). The study will consist of a 4 month randomised double blind parallel treatment period with either B-GOS of Placebo, and 1 month follow up period without treatments.
详细描述
With age, several important alterations occur within the gastrointestinal (GI) tract, that are responsible for altered microbial environment (e.g. reduced diversity and number of beneficial bifidobacteria and higher populations of enterobacteria and clostridia).
Research over the past two decades has provided evidence that administration of probiotics (live microorganisms which, when administered in adequate amounts, confer a health benefit on the host) could be used to optimise gut microbiota and prevent and treat a range of diseases, as well as enhance immune function. Somewhat less documented and more recent concept is the use of prebiotics (nondigestible 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). Prebiotics are naturally available in breast milk and in certain vegetables but can also be synthetic oligosaccharides of which the best known and the most researched examples include fructooligosaccharides (FOS) and galactooligosaccharides (GOS). B-GOS is a low molecular weight GOS mixture, shown to increase the number of probiotic bacteria, especially bifidobacteria, in younger and older adults, irritable-bowel sufferers and overweight adults. B-GOS also significantly decreases the colonisation and pathology of salmonellosis and incidence and duration of traveller's diarrhoea.
Our aim is to investigate the potential of B-GOS to beneficially influence the wellbeing and ageing in healthy adults (52-65 years old). The assessment would consist of various questionnaires covering quality of life, bowel function, mood and sleep and blood markers of inflammation and ageing.
