Опубликована: Июль 13, 2024

Dietary components, including dietary fiber, unsaturated fatty acids, and polyphenols, along with meal timing spacing, significantly affect the microbiota’s capacity to produce various metabolites essential for quality sleep overall health. This review explores role of gut microbiota in regulating through such as short-chain tryptophan, serotonin, melatonin, gamma-aminobutyric acid. A balanced diet rich plant-based foods enhances production these sleep-regulating metabolites, potentially benefiting aims investigate how habits composition, it produces, subsequent impact on related health conditions.

Modern habits are becoming more and disruptive to health. As our days often filled with circadian disruption stress exposures, we need understand how responses these external stimuli shaped their mediators can be targeted promote A growing body of research demonstrates the role gut microbiota in influencing brain function behavior. The response rhythms, which essential maintaining appropriate environment, known impacted by microbiota. Gut microbes have been shown alter host's modulate rhythmicity. Although studies demonstrated strong links between microbiota, rhythms response, such were conducted an independent manner not conducive understanding interface factors.

Multispecies probiotic administration reduces emotional salience and improves mood in subjects with moderate depression: a randomised, double-blind, placebo-controlled study

Psychological Medicine, Год журнала: 2022, Номер 53(8), С. 3437 - 3447

Опубликована: Фев. 7, 2022

Abstract Background The potential antidepressant properties of probiotics have been suggested, but their influence on the emotional processes that may underlie this effect is unclear. Methods Depressed volunteers ( n = 71) were recruited into a randomised double-blind, placebo-controlled study to explore effects daily, 4-week intake multispecies probiotic or placebo processing and cognition. Mood, anxiety, positive negative affect, sleep, salivary cortisol serum C-reactive peptide (CRP) assessed before after supplementation. Results Compared with placebo, increased accuracy at identifying faces expressing all emotions (+12%, p < 0.05, total 51) vigilance neutral (mean difference between groups 12.28 ms ± 6.1, 51). Probiotic supplementation also reduced reward learning (−9%, 51), interference word recall auditory verbal task (−18%, 50), did not affect other aspects cognitive performance.

Associations between gut microbiota and sleep: a two-sample, bidirectional Mendelian randomization study

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Опубликована: Авг. 14, 2023

Previous research has reported that the gut microbiota performs an essential role in sleep through microbiome-gut-brain axis. However, causal association between and remains undetermined.We performed a two-sample, bidirectional Mendelian randomization (MR) analysis using genome-wide study summary data of self-reported traits from MiBioGen consortium UK Biobank to investigate relationships 119 bacterial genera seven sleep-associated traits. We calculated effect estimates by inverse-variance weighted (as main method), maximum likelihood, simple model, median, MR-Egger methods, whereas heterogeneity pleiotropy were detected measured MR residual sum outlier method, Cochran's Q statistics, regression.In forward analysis, concluded genetic forecasts relative abundance 42 had effects on In reverse 39 genera, 13 which overlapped with analysis.In conclusion, our indicates may be involved regulation sleep, conversely, changes also alter microbiota. These findings suggest underlying reciprocal sleep.

Appraising the role of biotics and fermented foods in gut microbiota modulation and sleep regulation

Journal of Food Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 3, 2025

Abstract Sleep disturbances are increasingly prevalent, significantly impacting physical and mental health. Recent research reveals a bidirectional relationship between gut microbiota sleep, mediated through the microbiota–gut–brain axis. This review examines role of in sleep physiology explores how biotics, including probiotics, prebiotics, synbiotics, postbiotics, fermented foods, can enhance quality. Drawing from animal human studies, we discuss neurobiological mechanisms by which biotics may influence modulation neurotransmitters, immune responses, hormonal regulation. Key microbial metabolites, such as short‐chain fatty acids, highlighted for their supporting sleep‐related neurochemical processes. Additionally, this presents dietary strategies food processing technologies, like fermentation, innovative approaches enhancement. Although promising, available has limitations, small sample sizes, variability biotic strains dosages, reliance on subjective assessments. underscores need standardized protocols, objective assessments polysomnography, personalized interventions. Emerging findings highlight therapeutic potential improvement, though further large‐scale trials essential to refine strain selection, dosage, formulation. interdisciplinary exploration seeks advance food‐based interventions holistic managing disorders improving quality life.

Progress in Neurobiology, Год журнала: 2021, Номер 209, С. 102208 - 102208

Опубликована: Дек. 16, 2021

Sleep disorders have been linked to alterations of gut microbiota composition in adult humans and animal models, but it is unclear how this link develops. With longitudinal assessments 162 healthy infants, we present a so far unrecognized sleep-brain-gut interrelationship. First, report between sleep habits microbiota: daytime associated with bacterial diversity, nighttime fragmentation variability are maturity enterotype. Second, demonstrate link: diversity enterotype neurophysiology. Third, show that the relevant development: markers predict behavioral-developmental outcomes. Our results dynamic interplay sleep, microbiota, maturation brain behavior during infancy, which aligns newly emerging concept axis. Importantly, represent promising health targets since both can be modified non-invasively. As many diseases root early childhood, leveraging protective factors adequate age-appropriate infancy could constitute promoting factor across entire human lifespan.
