Pro(Biotic)s and Anti(Bacterial)s

Another piece of foodie mantra that turns out to be overhyping? It has now been claimed that so-called 'probiotics' may, in some cases, have negative effects on our gut (large intestine) bacterial flora (https://www.theguardian.com/science/2018/sep/06/probiotics-not-as-beneficial-for-gut-health-as-previously-thought). This appears to be especially the case when they are taken in conjunction with antibiotics (which will attack our flora as well as the bacterial infection they are prescribed for). The combination can produce profound gastro-intestinal disturbances.
