Probiotics have no effect on healthy adults

If you are been in a grocery store lately you’re probably well aware that probiotics are the latest health craze since the recent kale fiasco but once you wade through all the hype  do these expensive bacteria laden foods and drinks actually do any thing?  According to a team of researchers from Denmark the answer is a fig fat No.products3

The team looked at test data gathered on seven probiotic products and found no evidence that they changed the mix of faecal bacteria in healthy adults.  A larger sample size is needed to confirm once and for all if these products have any kind of influence on our inner microbiome but these initial results are pretty telling

Even if you don’t take probiotics you’ve likely heard quite a bit about them but for the uninitiated they’re basically living microorganisms that are designed to encourage the growth of healthy gut bacteria and aid digestive system function.  We produce our own probiotics internally but plenty of foods and drinks claim to boost their numbers.PJ-AO013A_pjPRO_D_20090112205236

Scientists from the Novo Nordisk Foundation Centre for Basic Metabolic Research at the University of Copenhagen whittled down over 1000 studies to identify seven probiotic products to test.

In the seven studies analysed the numbers of participants varied between 21 and 81 with ages ranging from 19 to 88 and they involved probiotic biscuits drinks sachets or capsules administered for periods of 21 to 42 days.

In only one of these studies did the team find a difference in gut bacteria between those participants who were taking probiotic supplements and those who weren’t  and the link between the two was slight.images

‘ According to our systematic review no convincing evidence exists for consistent effects of examined probiotics on faecal microbiota composition in healthy adults  despite probiotic products being consumed to large extent by the general population “ said team member Nadja Bnus Kristensen.

But the case is not entirely closed just yet because the sample sizes in each of these studies were very small. And as the researchers pint out someone needs to conduct a more wide reaching study to figure out what exactly is going on here
