Special Issue "The Links between Nutrition, Energy Metabolism, Aging and Cognition"
Deadline for manuscript submissions: 31 October 2021.
Interests: nutrition; neurophysiology; aging; chronobiology; energy metabolism
In modern societies, humans have evolved from physically active hunter-gatherers with a diet rich in fibers but low in sugar to sedentary persons with low physical activity and easy access to extremely rich food. If a modification of diet composition during evolution might have contributed to the expansion of human brain mass and complexity, the recent changes in diet (e.g., more sugar, more fat) might explain in part the increasing prevalence of obesity and associated metabolic disorders. At the same time, medical and social progress has led to an extension of lifespan, but with a rising prevalence of age-related diseases, such as neurodegenerative diseases. Studies in humans report that metabolic disorders (such as obesity or insulin resistance) are often comorbidities of cognitive declines and could be considered as risk factors for neurodegenerative diseases.
Gut microbiota, which stand at the interface between the environment and the organism, have also been extensively associated with energy homeostasis and metabolic control, in particular in relation to the effects of microbial metabolites on the gut–brain axis. More precisely, gut microbiota have a major impact on digestive efficiency and on the nutrients that are rendered available for energy homeostasis. It is well described that gut microbiota composition is flexible, in particular, in response to food composition, and, in turn, how the loss of intestinal microbial diversity is detrimental to energy balance and mental health.
This Special Issue will review current advances in the field of energy and metabolic regulations in relation to nutrition, with a specific emphasis on the role of gut microbiota. The focus will be on the effects of nutrition on brain function, and more specifically on the mechanisms that underline the neurodegeneration process. Contributions to both animal models and/or humans, as well as evolutionary perspectives, are encouraged.

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 papers will be 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
