I was looking at the microbiome from centurions that live around the world. One commonality they had is a very diverse microbiome. Centurions had most of the microbiome we have but they had many others not found in most now days. They could eat things many could not now days because we lack the microbiome to digest them. They had higher levels of bifidobacterium. They had higher levels of Akkermansia, Faecalibacterium Prausnitzii, they also had a variety of microbiota from the clostridium cluster XIVa which is the commensal that protect us from infection and most are butyrate producing. These are strains I believe contributed to their longevity because I found they were common in almost all the centurions but are not found in most others. Centurions also had high levels of acetate producing bacteria like Bifidobacterium Longhum and Bifidobacterium Infantis.
Centurions contain Coprococcus species like C Catus, C. Eutactus, C. Comes which produce short chain fatty acids and acetate. They break down glucose , fructose and other saccharides.
Anaerotruncus Colihomnis – spore forming, indole producing. It breaks down many types of sugars including glucose, manose and fructose.
Blautia Obeum – protects from vibrio cholerea.
Angerostipes Rhamnosivorans – butyrate producing. Can digest a variety of fibers and break down lactose.
Coprococcus Eutactus – butyrate producing, produces many types of short chain fatty acids.
Marvinbryantia Formatexigens – consumes oligosaccharides increases succinate. Can break down chitosan, xanthum, guar gum, and pectin.
Roseburia Inulinivorans – breaks down long chain inulin like chitosan, xanthum, guar gum, and pectin. It also produces butyrate.
Cristensenell Minuta – prevents obesity.
Christensenella Timonensis – prevents obesity.
Centurions have low levels of bacterioidetes and Streptococcus species of microbiota. They had normal levels of bacteroides which is usually elevated in those with inflammatory bowel disease. They also did not have Fusobacterium which is high in those with inflammatory bowel diseases. They did not have the pathogenic clostridium species which is probably because of the high levels and variety of Clostridium XIVa species they have which protects from the pathogenic Clostridium. They also had lowe levels of prevotella.
One thing I also found they had in common but not related to gut microbiome they strongly supported family and were not as prone to getting angry and being hateful.
