Nutrigenomics aims to evaluate the impact of dietary components on gene expression; in particular, diet is rich in functional groups that, interacting with DNA and histones, can modulate gene expression directly or through chromatin remodeling. Moreover, diet represents an important source of compounds necessary for healthy gut microbiota. Indeed, gut bacteria can produce short-chain fatty acids from fibers contained in vegetables, fruits, and whole grains, thanks to their ability to digest the β-1,4 glycosidic bond, distinctive of the fiber macromolecule.

One of the key points to promote proper nutrigenomic responses is to define adequate food intake and the proportion of macro- and micro-nutrients in accordance with the cultural dietary habits of different populations. Efforts should be addressed to promote education, in particular, to attract the interest of young generations, on the key role of early-life nutrition for the programming of adult health, and to instruct them on how to maintain health across life by a sustainable diet. Taking into account the impact of nutrigenomic research on population health, this Special Issue will publish original research papers, reviews, systematic reviews, and meta-analyses that will contribute to identify and characterize food rich in antioxidants as well as other food components useful to address proper nutrigenomics responses in our body, in order to promote health and appropriate dietary choices consistent with sustainable development. This Special Issue particularly welcomes articles from participants at the 4th European summer school on Nutrigenomics that will take place online on June, 21–25, 2021.

This collection will provide further in-depth insight into a range of work and ideas discussed at the event, and also will present recent progress in these areas for researchers beyond the event. The acceptance of an abstract for presentation at the Summer School does not necessarily guarantee the acceptance for publication in the Special Issue, as each article will undergo a peer-reviewed process as established by the usual high standards and guidelines of the journal.

Two free of charge publications are available to the best papers submitted to the Special Issue "Nutrigenomics and antioxidant components of diet" in Antioxidants (Impact Factor 5.014) by PhD Students/young Researchers registered to the 4th European summer school on nutrigenomics.
