Special Issue Information

Dear Colleagues,

Taste is the sensory modality considered of the most relevant factors that influences nutrition and health. This role is based on data showing that taste varies significantly among individuals, influencing food preferences and therefore eating behavior. Variations of taste sensitivities can be due to sundry factors (e.g., genetics, environment and age), which can thus constitute risk factors for unbalanced eating habits and serious health morbidities. Taste perception plays important roles also in various extra-oral tissues where it mediates diverse physiological functions, the variations of which are associated with several human disorders. For this Special Issue, we invite original research articles and comprehensive reviews that focus on taste perception, eating behavior, their implications in nutrition and health, and the genetic and non-genetic factors involved.

Potential topics include, but are not limited to, the molecular basis of taste sensitivity; how pathological conditions, medical treatments, aging processes, microbiota, etc., influence taste perception, eating behaviour, or health; physiological factors that impact taste perception, eating behavior and nutrition in humans; the genetic and non-genetic factors involved in taste perception.

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.

The salivary protein, Gustin/carbonic anhydrase VI, has been described as a trophic factor responsible for the growth of taste buds. We found, in a genetically homogeneous population, that the polymorphism rs2274333 (A/G) of the Gustin gene is crucial for the full functionality of the protein and is associated with taste sensitivity. However, other studies have failed to find this evidence. Here, we verified if Gustin gene methylation can affect the salivary levels of the protein, also concerning the polymorphism rs2274333 and PROP bitter responsiveness. The Gustin gene methylation profiling and the quantification of the Gustin salivary levels were determined in sixty-six volunteers genotyped for the polymorphism rs2274333 (A/G) (Ser90Gly in the protein sequence). The fungiform papillae density was also determined. The results confirm our earlier observations by showing that AA genotypes had a greater density of fungiform taste papillae, whereas the GG genotypes showed a lower density. We also found variations in the protein levels in the three genotype groups and an inverse relationship between Gustin gene methylation and the salivary levels of the protein, mostly evident in AA and ST volunteers, i.e., in volunteers who would be carriers of the functional isoform of the protein. These findings could justify the conflicting data in the literature. Full article
