Cranberries have long been hailed a 'superfood' for their cancer-fighting properties but now they have been proven to benefit our gut health, say experts.
For the first time, certain friendly microbes have been found to grow when fed a carbohydrate in the fruit.
Good intestinal bacteria not only improves digestion but also our brain health, mood, emotions, energy levels, and weight loss.
Whats more, our microflora has also increasingly been linked to many aspects of health, including aging, arthritis, depression, cancer and heart conditions.
Now cranberries – in supplement form – may be a candidate to improve our gut health, says study author professor David Sela, nutritional microbiologist at the University of Massachusetts Amherst.
He said: 'They make molecules and compounds that help us, or they make it to help some of the hundreds of other kinds of beneficial members of the [gut health] community.
'There are thought to be as many bacterial cells in our bodies as our own human cells, so we're basically eating for two.
'These gut bacteria are extremely significant to us, they really are very important. Our food makes a difference for us as well as the beneficial microbes that we carry around with us.'
These probiotics are found in adults to some degree but the highest concentrations are found in the guts of newborn, breast-fed babies, explains professor Sela.
'They are consuming things we can't digest, or they are helping other beneficial microbes that we find it hard to introduce as probiotics, or their presence can help keep pathogens away,' he said.
It is not clear yet what the impacts to health are but the findings are promising.
'Prebiotics and probiotics might interact with our own physiology to help balance the microbiome, and we already know that when things are not in balance you can get problems like inflammation,' he added.
'Underlying chronic inflammation can lead to or worsen many different medical conditions.'
