Special Issue Information
Dear Colleagues,
Food allergy is a global health problem that affects about 1.5% of adults and 5% of young children. Besides environmental and genetic factors, the exact causes of food allergy are still largely unknown. Delayed maturation of the infantile immune system, also as a consequence of a less diversely developed intestinal microbiota, is one of the factors that is hypothesized to be associated with the rapid increase of allergies.
Sensitization to food allergens more often occurs in children with atopic dermatitis, which led to the hypothesis that allergens enter the broken skin and reach the immune system. The hypothesis is based on a skin–gut axis, where the gut plays an important role in the allergic reaction.
The repeated inflammation, damage, and repair of the tissue characteristic of allergic diseases may also increase the risk of unfavourable cardio-metabolic profiles such as cardiovascular disease (CVD) and type 2-diabetes. It is unknown whether the allergic inflammation stimulates the metabolic one or vice versa.
Once a patient has developed a food allergy, an elimination diet is inevitable. The nutritional hazards, risks of allergic reactions to new allergens, problems with misused labelling (precautionary allergen labelling(PAL)), and problems with the re-introduction of allergens lead to worse QoL in patients with food allergies.
The composition of the Western diet is also associated with allergies. Insufficient intake of, for example, dietary fibre leads to less production of short-chain fatty acids (crucial metabolic products of gut microbiota responsible for many protective effects against food allergy), a less favourable composition of these microbiota, and less mild stimulation of the gut-associated lymphoid tissue (GALT).
Possible topics include but are not limited to the following:
- Skin–gut axis in sensitization to food allergens;
- Gut microbiota and food allergy;
- Link between TH1 and TH2 immune disorders, what can be learned from big data.
- Elimination diets, nutritional hazards, and the re-introduction of food allergens;
- Immunomodulation in food allergy;
- Effects postbiotics on atopic disorders.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
