Special Issue Information
Dear Colleagues,
Different dietary patterns, such as the Mediterranean, high-fiber, plant-based, high-protein, ketogenic, and Western diets, have been linked to varying effects on neuropsychiatric symptoms, neuroprotection, and neuroinflammation, influencing outcomes from stress-related disorders to neurodegeneration. The gut microbiome interacts with dietary compounds, processes macronutrients and micronutrients, contributes to energy balance, and produces metabolites, many of which have neuroactive properties. Evidence demonstrates that diet is a major determinant of gut microbiome composition, and alterations in diet–microbiome interactions can impact host health, including brain function. This relationship has led to the concept of the diet–microbiota–gut–brain axis, which encompasses the immune system, metabolism, endocrine signaling, and neuronal pathways.
Several factors should be considered when interpreting diet–microbiota–gut–brain interactions, including environmental influences, food composition, geography, cultural and genetic factors, and aging. A deeper understanding of these interactions may pave the way for targeted dietary interventions and precision nutrition strategies to optimize brain health and mitigate neuropsychiatric and neurodegenerative disorders.
We invite researchers to submit original research, including cross-sectional, cohort, and interventional studies on animal models and human populations, systematic reviews, and meta-analyses. Submissions should explore the complex interplay between diet, gut microbiota, and brain function.
We look forward to receiving your contributions to this Special Issue.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
