Nutrigenomics, Nutrigenetics and the Immune System: Implications for Health

Dear Colleagues,

The current COVID-19 pandemic has caused a global health crisis and economic devastation, highlighting the need to increase scientific knowledge about factors that can promote the optimal functioning of the immune system. The optimal nutritional balance is essential to promote health, being one of the most important factors to maintain the proper status of immune system to prevent and fight infectious diseases.

In this sense, the new knowledge in Nutritional Genomics applied to the health of the immune system is of great relevance in the current context. On the one hand, advances in Nutrigenomics help to establish the underlying biological mechanisms that sustain the relationship between nutrients and their beneficial effects on the immune system, through modulation of gene expression. On the other hand, Nutrigenetics will help to explain divergences in the immunomodulatory effect triggered by nutrients, depending on the genetic background of each individual.

Overall, scientific advances in Nutrigenomics and Nutrigenetics in the field of the state of the immune system are crucial to promote the health of the population across the implementation of Personalized Precision Nutrition strategies that allow us a greater capacity to avoid infectious diseases and defeat them with fewer complications.

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.
