Special Issue Information
Dear Colleagues,
Food additives are substances incorporated into processed and ultra-processed food to extend shelf life, enhance flavor and appearance, and improve texture and nutritional quality. The use of natural substances for food preservation dates back to ancient times. However, with the advent of industrial-scale food production in the 19th century, various chemical food additives were introduced into the modern food supply.
Many food additives are considered safe under regulations. Nutritionally fortified packed processed foods play an important role in combating hunger due to their convenient storage, transportation, and distribution. Nevertheless, the widespread use of chemical food additives in the contemporary food system has raised concerns about its potential long-term impact on human health.
At the molecular level, recent studies indicate that certain additives have the potential to regulate gene expression and influence metabolic pathways. At the population level, higher consumption of ultra-processed foods has been associated with gut health, metabolic disease, immunomodulation, and carcinogenesis.
This Special Issue proposes consolidating cutting-edge investigations on how food additives interact with molecular pathways in the human body and contribute to the development of modern diseases. Particular emphasis will be on additives such as artificial sweeteners, preservatives, colorants, and emulsifiers and their roles in regulating such key pathways as inflammation, immune and oxidative stress response, and lipid metabolism.
We invite original research and review articles exploring molecular mechanisms of the interactions among food additives, genomics, epigenomics, and microbiome; in vivo and in vitro experimental research on biological responses to additives; and population-based studies examining associations between processed and ultra-processed food consumption and disease burden. By enhancing our knowledge of the gene-additive interaction and their biological consequences, this Special Issue seeks to inform the development of regulations, support safer food formulation, and promote future investigations in preventive nutrition and public health.

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.
