Medicinal foods that promote brain health, such as Gastrodia elata Bl, black sesame seeds (Sesamum indicum L.), walnuts (Juglans regia L.), jujube (Ziziphus jujuba Mill.), Poria cocos, and Coix seeds, possess antioxidant and neuroprotective properties, as well as modulating effects on the intestinal microbiota. This study evaluated the effects of functional biscuits formulated with these medicinal foods on the intestinal mucosal microbiota, brain function, and antioxidant activity in mice. Forty male SPF-grade C57BL/6J mice were randomly divided into a blank control group (NG), low-dose functional biscuit group (GLG), medium-dose functional biscuit group (GMG), and high-dose functional biscuit group (GHG). After 42 days of continuous feeding with the functional biscuits, changes in the richness, diversity, and community structure of the intestinal mucosal microbiota were observed. Compared with the NG group, norepinephrine (NE) levels in the hippocampus significantly increased in the GLG, GMG, and GHG groups, while gamma-aminobutyric acid (GABA) levels showed no significant difference. In the GMG and GHG groups, malondialdehyde (MDA) levels in the liver significantly decreased, and acetylcholine transferase (ChAT) levels in the hippocampus significantly increased. Additionally, multiple bacterial genera were found to be correlated with the NE, ChAT, and MDA levels. These findings indicate that functional biscuits have effects on modulating the intestinal mucosal microbiota composition, enhancing brain function, and exhibiting antioxidant activity, making them a beneficial functional food for brain health.","PeriodicalId":93908,"journal":{"name":"Bioscience of microbiota, food and health","volume":"44 2","pages":"171-181"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11957763/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the effects of LcS ingestion on URTIs and MPC activation. Two hundred healthy workers aged 23-59 consumed a fermented milk drink containing 4.0 × 1010 CFU of LcS (LcS-FM) or a control unfermented milk drink (CM) daily for 28 days during winter. The incidence and severity of URTIs were surveyed using a questionnaire. Peripheral blood mononuclear cells (PBMCs) and serum samples were analyzed for immune cell subsets, cell surface molecules, and cytokines. The LcS-FM group showed a significantly lower incidence and severity of URTIs than the CM group. Notably, the incidence, cumulative incidence, and severity of URTI symptoms were markedly suppressed after 14 days of consumption. LcS-FM also affected MPC activation during this period. The expression of HLA-DR on conventional dendritic cells (cDCs) and monocytes (Mos) was significantly higher in the LcS-FM group on days 14 and 28, along with the expression of CD86 on cDCs on day 14. Among the study participants positive for serum interferon (IFN), the IFNα2 concentration in the LcS-FM group was higher than that in the CM group on day 28. These findings suggest that LcS suppresses the incidence and severity of URTIs in healthy adults, which is associated with the activation of cDCs and Mos.","PeriodicalId":93908,"journal":{"name":"Bioscience of microbiota, food and health","volume":"44 3","pages":"215-226"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12236165/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been indicated that its impact on the gut microbiota may mediate these beneficial effects. As a result, we hypothesized that IF may impact the human gut microbiota. A systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol using the PubMed, Scopus, and CINAHL databases. We registered our systematic review protocol in PROSPERO under registration number CRD42021270050. Human intervention studies published until April 30, 2023, were included. The quality of the included studies was assessed using National Institutes of Health (NIH) quality assessment study tools for intervention studies. The search in the database returned 166 studies, of which 13 matched all criteria for the final qualitative analysis. The body of evidence suggests that IF modulates human gut microbiota alpha and beta diversity in lean (relatively healthy) and relatively healthy overweight/obese individuals but not in individuals with metabolic syndrome. Furthermore, IF also alters human gut microbiota composition in all phenotypes. Of interest, the gut microbiota taxa or microbial metabolites after an IF intervention are associated with metabolic markers. According to this review, IF influences the diversity and taxonomic levels of the human gut microbiota.

In this study, we traced the microbiota in four lots of starters manufactured in a newly established brewery and evaluated the lot-to-lot variation and characteristics of the microbiota in the brewery. The results of a 16S ribosomal RNA amplicon analysis showed that the starters brewed in the second brewing year had a more diverse microbiota than those in the first brewing year. Among the LAB predominated at the middle production stage, lactococci, including Leuconostoc spp., were detected in all the lots, while lactobacilli predominated for the first time in the second year. These results suggest that repeated brewing increased microbial diversity and altered the microbial transition pattern in the kimoto-style fermentation starters. Phylogenetic analyses for the LAB isolates from each starter identified Leuconostoc suionicum, Leuconostoc citreum, and Leuconostoc mesenteroides as predominant lactococci as well as a unique lactobacillus in place of Latilactobacillus sakei. We also found that a rice koji-derived Staphylococcus gallinarum with nitrate-reducing activity was generally predominant during the early production stage, suggesting that there was a case in which staphylococci played a role in nitrite production in the starters. These findings are expected to contribute to the understanding of the diversity of microbiota in kimoto-type sake brewing and enable control of the microbiota for consistent sake quality.","PeriodicalId":93908,"journal":{"name":"Bioscience of microbiota, food and health","volume":"43 3","pages":"250-259"},"PeriodicalIF":2.5,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11220333/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141536227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
