NewsFeeding your good gut bacteria through fibre in diet may boost body against infections
Researchers who used computational approaches to analyse the gut microbiome composition of over 12,000 peoplefrom their stool samples found that a person’s microbiome ‘signature’ can predict whether their gut is likely to be colonised by Enterobacteriaceae.
