Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue of Nutrients entitled “Effects of Dietary Intake on Cognitive Function”. This issue invites submissions describing original research or systematic reviews and meta-analyses. Manuscripts addressing the effects of dietary interventions on cognitive outcomes and mental health, in either healthy subjects or those with metabolic disorders, are especially welcome.

Nutrition is an important component of a healthy society and is becoming an increasingly important focus of a wide range of research agendas. There is abundant evidence for the role of good-quality nutrition in physical growth, health and quality of life. Less is known about the direct and indirect effects (for example in obesity or metabolic syndrome) of dietary intake on mental health and cognitive function. Several metabolic disorders are characterized by a partial or full inability to metabolize certain amino acids and cognitive and mental health problems. Examples include phenylketonuria, tyrosinemia Type 1, and maple syrup urine disease. These used to be treated solely with highly restrictive dietary treatments. Significant refinement has taken place over recent decades regarding dietary treatment, and for some disorders medication has been introduced that diminishes reliance on dietary treatment alone. However, dietary restrictions are often still part of the treatment regimen, which could increase chances of nutritional shortages or imbalances, particularly after long-term exposure. In many metabolic disorders, cognitive and mental health problems cannot solely be explained by disease-specific biomarkers. Other biomarkers, indicative of overall or “other”’ nutrient intake, might help to elucidate the underpinnings of the cognitive–behavioral phenotype observed in these disorders.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

This study aimed to assess the association between dietary patterns and cognitive function among Qatari adults. In a cross-sectional analysis, data on 1000 Qatari adults attending the Qatar Biobank Study (QBB) aged ≥18 years were obtained. Using factor analysis, dietary patterns were constructed based on habitual dietary intake assessed by food frequency questionnaires (FFQs). The mean reaction time (MRT) derived from self-administered touch screen tests was used as an indicator of cognitive function. The association between dietary patterns and MRT was investigated using linear regression. The mean age of the participants was 35.8 (SD 10.3) years, and the mean MRT was 715.3 (SD 204.1) milliseconds. Three dietary patterns were identified. The “traditional” dietary pattern, characterized by high intakes of white rice, mixed dishes and soups/starters possibly high in saturated fat and sodium, was positively associated with MRT. In the multivariable model, comparing the highest to lowest quartiles of the traditional pattern, the regression coefficient for MRT was 50.0 (95% CI 16.9, 83.1; p for trend 0.001). There was an effect modification of diabetes and age on the association between the “modern” dietary pattern and MRT. The “convenient” dietary pattern was not associated with cognition. In conclusion, the traditional rice-based dietary pattern may be associated with poor cognitive function. Full article

Background/Objectives: Recent research highlights the growing interest in the impact of nutrition on cognitive health and function in disease, as dietary habits are increasingly recognized as crucial factors in relation to brain function. This focus is especially important given the rising prevalence of neurodegenerative diseases and the cognitive decline associated with poor dietary choices. Links are now being sought between brain function and the microbiota and gut–brain axis. Mechanisms are proposed that include low-grade chronic neuroinflammation, the influence of short-chain fatty acids, or the disruption of glial cells and transmitters in the brain. Methods: We reviewed the articles on pubmed. This is not a systematic review, but of the narrative type. We wanted to outline the issue and summarise the latest information. Results: The axis in question has its foundation in nutrition. It has been reported that diet, particularly the components and the timing of food intake, has an impact on cognitive processes. The Mediterranean diet is most often cited in the literature as being beneficial to health. In order to obtain a more complete view, it is worth considering other dietary patterns, even those that impair our health. Conclusions: Determining what is beneficial and what is not will allow us to develop a speronized strategy for the prevention of, and fight against, cognitive impairment. Appropriately selected supplements, the functions of which we have also discussed, may prove supportive. Full article
