To investigate whether vitamin B12 (VB12) is essential for normal propionate fermentation by colonic bacteria, via the succinate pathway, we examined if high-amylose cornstarch (HACS) feeding activated such a pathway, if high HACS feeding impaired propionate fermentation, and if oral VB12 supplementation normalized propionate fermentation. Male rats were given control, 20% HACS or 3% fucose diets (Expt. 1); a VB12-free control diet or one supplemented with 5-30% HACS (Expt. 2); and the 20% HACS diet supplemented with 0.025-25 mg/kg of VB12 (Expt. 3), for 14 d. HACS feeding significantly increased cecal succinate concentration, activating the succinate pathway (Expt. 1). Cecal cobalamin concentration in 20% and 30% HACS groups was about 75% of that in the control group (Expt. 2). Cecal succinate and propionate concentrations significantly increased and decreased in 30% HACS groups, respectively, compared with the control group. Although HACS group supplemented with 0.025 mg/kg of VB12 had a low concentration of cecal propionate, adding high amounts of VB12 to HACS diets provided sufficient amounts of VB12 to rat ceca and increased cecal propionate concentration (Expt. 3). Compared with the non-HACS group, the relative abundance of Akkermansia muciniphila, but not Bacteroides/Phocaeicola, was lower in the HACS counterpart and showed improvement with increased VB12 doses. To summarize, feeding high HACS decreased and increased cecal VB12 and succinate concentrations, respectively. Furthermore, colonic delivery of sufficient amounts of VB12 to rats likely reduced accumulation of succinate and normalized propionate fermentation.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 2","pages":"139-149"},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140861490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular mechanisms underlying the relationship between these host effects and their impact on gut microbiota remain unclear. Here, we demonstrated that intake of different dietary lipids improved glucose tolerance by modulating gut microbiota. The results of our analysis show that the taxa of bacteria that increase in number as a result of dietary lipid intake play an important role in glucose metabolism. Thus, we have identified a new mechanism underlying the function of dietary lipids in regulating glucose homeostasis.

Its cumulative urinary excretion accounted for less than 20% of the dose administered. After a single dose of BR extract (C3G40) containing C3G was orally administered (300 mg C3G/kg body weight), the C3G plasma concentration peaked at 30 min and then rapidly declined within 4 h. The extent of the cumulative urinary excretion of C3G, together with the area under the curve (AUC) of the plasma C3G concentration, indicated a bioavailability of approximately 0.5-1.5%. These results suggest that C3G was rapidly absorbed from the gastrointestinal tract in rats; however, its plasma concentration was very low. We also examined the enhancing effect of allyl isothiocyanate (AITC), a pungent component of wasabi, on the gastrointestinal absorption of C3G in rats.
