After seeing a few articles around recently about how beneficial gut bacteria are, the gut microbiome, faecal transplants etc., I started wondering how we can best boost and repopulate what lives in our guts. Please post any suggestions you have here. Best probiotic I've taken and still take is: http://www.optibacprobiotics.co.uk/shop/for-daily-wellbeing.html which contains: Probiotic culture(Lactobacillus rhamnosus Rosell-11, Lactobacillus acidophilus Rosell-52, Bifidobacterium longum Rosell-175, Lactococcus lactis Rosell-1058, Bifidobacterium breveRosell-70, Bifidobacterium bifidum Rosell-71); Prebiotic: Fructooligosaccharides (FOS) I've also read recently that plant fibres help feed the bacteria already in our gut. BUT seeing as probiotics are usually lactobacillus, how do we get other beneficial strains? For those who've taken antibiotics, repopulating the gut completely may be necessary so how is it best to go about that? Please, list the types of bacteria present in anything you suggest if possible so those who want to repopulate with different strains can see where to find appropriate sources.
