type constipation (pelvic floor dyssynergia), diarrhoea, faecal incontinence, hirschsprung’s disease, gastroparesis and achalasia. Promoting gut health optionally comprises promoting health of the gut microbiome in a subject. In an embodiment, promoting gut health of the gut microbiome comprises one or more of: increasing the level and/or activity of one or more beneficial bacteria, decreasing or maintaining the level and/or activity of one or more non-beneficial bacteria, increasing the resistance of the gut microbiome, increasing the resilience of the gut microbiome, and increasing the diversity of the gut microbiome. As used herein “resistanceof the gut microbiome”refers to the insensitivity of the gut microbiome to a disturbance. As used herein “resilienceof the gut microbiome”refers to the rate of the recovery of the gut microbiome after a disturbance (e.g. a disturbance may reduce the number or type of microorganism in the microbiome). In an embodiment, the beneficial bacteria is selected from one or more or all of: lactic acid bacteria, Bifidobacteria, Bacteroidetes, Baciullus, Streptococcus, Escherichia, Enterococcus, Anaeropstipes, Bacillus, Odoribacter, Victivallis (phylum Lentisphaerae) and unclassified Lentisphaerae, unclassified Marinilabiaceae and Anaerophaga (family Marinilabiaceae), Anaerophaga, Cerasicoccus, Roseburia, and/or Shigella species. In an embodiment, the lactic acid bacteria is selected from one or more of the genera selected from: Lactobacillus, Leuconostoc, Pediococcus, Lactococcus, Streptococcus, Aerococcus, Carnobacterium, Enterococcus, Oenococcus, Sporolactobacillus, Tetragenococcus, Vagococcus and Weissella. In an embodiment, the lactic acid bacteria is selected from one or more or all of: Lactobacillus plantarum, Leuconostoc mesenteroides, Lactobacillus rhamnosus, Lactobacillus pentosus, Lactobacillus brevis, Lactococus lactis, Lactobacillus acidophilus, Lactobacillus brevis, Lactobacillus casei, Lactobacillus delbrueckii, Lactobacillus fermentum, Lactobacillus gasseri, Lactobacillus johnsonii, Lactobacillus lactis, Lactobacillus paracasei, Lactobacillus reuteri, Pediococcus pentosaceus and Pedicoccus acidilacti. In an embodiment, the Bifidobacteria is selected from one or more of: Bifidobacteria adolescentis, Bifidobacteria animalis, Bifidobacteria bifidum, Bifidobacteria breve, Bifidobacteria infantis, Bifidobacteria longum, and Bifidobacteria thermophilum. In embodiment, the Baciullus is selected from one or more of: Baciullus cereus, Baciullus clausii, Baciullus coagulans, Baciullus licheniformis, Baciullus pumulis and Baciullus subtilis.
