Microbes
Microbes are microscopic organisms living in and on the human body, shaping health through digestion, vitamin production, and immune protection. When microbial balance is disrupted, disease can occur. This guide explains key microbe types—bacteria, viruses, fungi, protozoa, and archaea—plus major pathogenic and beneficial examples.

What was reviewed?
This review evaluated dietary, pharmacologic, and lifestyle strategies shown to increase the abundance of Akkermansia muciniphila in the gut, with emphasis on evidence from animal and human intervention studies. The author critically synthesized data on how specific dietary components, prebiotics, probiotics, drugs, and environmental factors influence A. muciniphila levels and how these changes relate to obesity, diabetes, inflammation, and metabolic health. The review also discussed proposed mechanisms linking increased A. muciniphila abundance to improved gut barrier integrity and reduced metabolic endotoxemia.
Who was reviewed?
The review integrated findings from multiple mouse models of diet-induced obesity, leptin deficiency, atherosclerosis, and diabetes, alongside limited but informative human dietary intervention studies in healthy individuals, patients with obesity, irritable bowel syndrome, Crohn’s disease, and metabolic disorders. No new cohorts were studied, but both animal and human populations were critically compared to assess translational relevance.
What were the most important findings?
Across studies, A. muciniphila abundance consistently showed an inverse association with obesity, insulin resistance, systemic inflammation, and circulating lipopolysaccharide levels. Direct supplementation with live A. muciniphila in mice reliably restored its abundance under high-fat diet conditions and improved metabolic outcomes without broadly altering overall microbiota composition, supporting its role as a functional keystone species. Among dietary interventions, fructo-oligosaccharides emerged as the most consistent prebiotic for promoting A. muciniphila growth, often restoring levels reduced by high-fat diets and improving glucose tolerance and fat mass. Certain polyphenol sources, such as cranberry and Concord grape extracts, markedly increased A. muciniphila in animal models, whereas others showed no effect, highlighting compound-specific activity. Human studies indicated that higher FODMAP intake was associated with increased A. muciniphila abundance, while restrictive low-FODMAP diets reduced it. Metformin consistently increased A. muciniphila abundance in animal models, and antibiotic pretreatment abolished metformin’s metabolic benefits, implicating A. muciniphila and reduced endotoxemia as mediators. Major microbial associations included links with improved mucus thickness, increased goblet cell numbers, and secondary enrichment of SCFA-producing taxa.
What are the greatest implications of this review?
This review establishes A. muciniphila as a diet- and drug-responsive microbiome target with clear relevance to metabolic and inflammatory disease. For clinicians, it highlights that increasing A. muciniphila abundance depends on specific nutritional patterns rather than generalized fiber intake and that therapeutic response likely varies by host context. The findings support precision nutrition and microbiome-informed strategies aimed at restoring mucus integrity and reducing metabolic endotoxemia.
Akkermansia muciniphila
Akkermansia muciniphila is a mucus-layer specialist that has shifted from “odd gut commensal” to one of the most mechanistically characterized next-generation probiotic candidates. First isolated from human feces using gastric mucin as the sole carbon and nitrogen source, it is adapted to life at the mucus–epithelium interface, where it converts host mucins into metabolites (notably acetate and propionate) that can feed other microbes and influence host physiology. Its genome encodes an unusually rich secretome for mucin foraging, dozens of predicted glycoside hydrolases, sulfatases, proteases, and sialidases, supporting stepwise dismantling of complex O-glycans and the mucin backbone.
Prebiotics
Prebiotics are non-digestible fibers that selectively promote the growth of beneficial gut bacteria, offering a range of health benefits from improved digestion and immune function to enhanced metabolic health. Prebiotics are an essential part of a healthy diet that supports both gut and overall well-being.
Probiotics
Probiotics are live microorganisms that offer significant health benefits when administered in adequate amounts. They primarily work by modulating the gut microbiome, supporting a balanced microbial ecosystem. Probiotics have been shown to improve gut health, modulate immune responses, and even influence metabolic and mental health disorders. With growing evidence supporting their therapeutic potential, probiotics are increasingly recognized for their role in treating conditions like irritable bowel syndrome (IBS), antibiotic-associated diarrhea (AAD), and even mental health conditions like depression and anxiety through their impact on the gut-brain axis.
Major Microbial Associations (MMAs)
Major Microbial Associations (MMAs) are fundamental in understanding disease-microbiome interactions and play a crucial role in advancing microbiome-targeted interventions aimed at treating or preventing diseases through microbial modulation.
Short-chain Fatty Acids (SCFAs)
Short-chain fatty acids are microbially derived metabolites that regulate epithelial integrity, immune signaling, and microbial ecology. Their production patterns and mechanistic roles provide essential functional markers within microbiome signatures and support the interpretation of MBTIs, MMAs, and systems-level microbial shifts across clinical conditions.
