Special Issue Information
Dear Colleagues,
“You are what you eat” could not be truer, given this day and age. Gone are the days when the gut, especially the small intestine, was thought to be designated for digesting and absorbing food. Research over the past 50 years has demonstrated that the intestine, being one of the privileged sites coming into direct physical contact with food, primes the body for hunger and appetite signals by communicating with the brain. Obesity calibrates the body to a different threshold, such that these signals are altered, as is the perception of eating and, more recently, food behaviors, too. This remarkable phenomenon is called “sensing” and can be thought of as a system with sensors that detects, processes, and transmits signals to and from the central nervous system to maintain energy homeostasis.
This Special Issue focuses on expanding knowledge on intestinal nutrient sensing and the impact of diet and obesity on the sensing, processing, and transmission of luminal nutrient status to the brain. Research encompassing but not limited to the effects of single and combination nutrients on gut health, the release of gut peptides, appetite and satiety behaviors, molecular and cellular mechanisms of taste, the transmission of vagal information, and uncovering novel sensors and receptors along the gut-brain axis. We welcome submissions of original hypothesis-driven research, systematic reviews, meta-analyses, and clinical trials. Pilot and feasibility studies are eligible for submission.

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.
