The gut microbiota plays a key role in mental health, with growing evidence linking its composition to anxiety and depressive disorders. Research on this topic has expanded significantly in recent years. This review explores alterations in the gut microbiota of individuals with anxiety disorders and examines the potential therapeutic effects of probiotics. Background/Objectives: This review… Continue reading The Impact of Gut #Microbiota on the Development of #Anxiety Symptoms—A Narrative Review

#Dairy Consumption and the Colonic Mucosa-Associated Gut #Microbiota in Humans—A Preliminary Investigation
Background: Dairy consumption has been associated with various health outcomes that may be mediated by changes in gut microbiota. Methods: This cross-sectional study investigated the association between the colonic mucosa-associated gut microbiota and the self-reported intake of total dairy, milk, cheese, and yogurt. A total of 97 colonic mucosal biopsies collected from 34 polyp-free individuals… Continue reading #Dairy Consumption and the Colonic Mucosa-Associated Gut #Microbiota in Humans—A Preliminary Investigation
Microbial metabolites tune #amygdala neuronal hyperexcitability and #anxiety-linked behaviors
Changes in gut microbiota composition have been linked to anxiety behavior in rodents. However, the underlying neural circuitry linking microbiota and their metabolites to anxiety behavior remains unknown. Using male C57BL/6J germ-free (GF) mice, not exposed to live microbes, increased anxiety-related behavior was observed correlating with a significant increase in the immediate early c-Fos gene… Continue reading Microbial metabolites tune #amygdala neuronal hyperexcitability and #anxiety-linked behaviors
Effects of Vegetable and Fruit #Juicing on Gut and Oral #Microbiome Composition
Background: In recent years, juicing has often been promoted as a convenient way to increase fruit and vegetable intake, with juice-only diets marketed for digestive cleansing and overall health improvement. However, juicing removes most insoluble fiber, which may diminish the health benefits of whole fruits and vegetables. Lower fiber intake can alter the microbiota, affecting… Continue reading Effects of Vegetable and Fruit #Juicing on Gut and Oral #Microbiome Composition
#Sugar-sweetened beverage intake, gut #microbiota, circulating metabolites, and #diabetes risk in Hispanic Community Health Study/Study of Latinos
Highlights• Sugar-sweetened beverage intake was associated with nine gut bacteria abundances• These bacteria were correlated with aromatic and branched-chain amino acid metabolites• These bacteria were correlated with glycerophospholipids• These gut microbial metabolites were associated with diabetes risk SummaryNo population-based studies examined gut microbiota and related metabolites associated with sugar-sweetened beverage (SSB) intake among US adults.… Continue reading #Sugar-sweetened beverage intake, gut #microbiota, circulating metabolites, and #diabetes risk in Hispanic Community Health Study/Study of Latinos
Comparison between two divergent diets, #Mediterranean and #Western, on #gut #microbiota and cognitive function in young sprague dawley rats
Clinical studies strongly suggest the importance of diet quality on cognition in youth populations (15–24 years). The Mediterranean diet (MeDi) has been shown to improve cognition in contrast to the commonly consumed Western diet (WD). The gut microbiota may serve as a mechanism for diet-induced changes in cognition. Ten-week-old male Sprague Dawley rats were assigned a… Continue reading Comparison between two divergent diets, #Mediterranean and #Western, on #gut #microbiota and cognitive function in young sprague dawley rats
Gut #microbiota regulates #stress responsivity via the circadian system
SummaryStress and circadian systems are interconnected through the hypothalamic-pituitary-adrenal (HPA) axis to maintain responses to external stimuli. Yet, the mechanisms of how such signals are orchestrated remain unknown. Here, we uncover the gut microbiota as a regulator of HPA-axis rhythmicity. Microbial depletion disturbs the brain transcriptome and metabolome in stress-responding pathways in the hippocampus and… Continue reading Gut #microbiota regulates #stress responsivity via the circadian system
#Antibiotics damage the #colonic mucus barrier in a #microbiota-independent manner
Antibiotic use is a risk factor for development of inflammatory bowel diseases (IBDs). IBDs are characterized by a damaged mucus layer, which does not separate the intestinal epithelium from the microbiota. Here, we hypothesized that antibiotics affect the integrity of the mucus barrier, which allows bacterial penetrance and predisposes to intestinal inflammation. We found that… Continue reading #Antibiotics damage the #colonic mucus barrier in a #microbiota-independent manner
Strain-specific gut #microbial signatures in type 2 #diabetes identified in a cross-cohort analysis of 8,117 metagenomes
The association of gut microbial features with type 2 diabetes (T2D) has been inconsistent due in part to the complexity of this disease and variation in study design. Even in cases in which individual microbial species have been associated with T2D, mechanisms have been unable to be attributed to these associations based on specific microbial… Continue reading Strain-specific gut #microbial signatures in type 2 #diabetes identified in a cross-cohort analysis of 8,117 metagenomes
