The identification number must be included at the end of the abstract.
Conflict of interest
Authors: The authors must declare explicitly and individually any potential, direct or indirect, financial or nonfinancial conflict of interest, etc., and any conflict of interest with ad hoc referees.
Ad hoc referees: If any of the referees declare a conflict of interest, the Editorial Board will send the manuscript to another ad hoc referee.
The Journal only publishes original articles in English. However, the authors may submit the articles in Portuguese, and if the article is accepted for publication, the Journal will provide the name and contact information of translators certified by the Journal. The translation is paid for by the authors.
Original: contributions that aim to disclose the results of unpublished researches, taking into account the relevance of the theme, the scope and the knowledge generated for the research area (maximum limit of 3,500 thousand words).
Review (by invitation): synthesis of the knowledge available on a given theme, based on analysis and interpretation of the pertinent literature, aiming to make a critical and comparative analysis of the works in the area and discuss the methodological limitations and its scope. It also allows the indication of perspectives of continuing studies in that line of research (maximum limit of 4 thousand words). There will be a maximum of two reviews per issue.
Scientific note: partial unpublished data of an ongoing research (maximum limit of 1,500 thousand words).
Thematic Section (by invitation): section whose aim is to publish 2 or 3 coordinated articles from different authors covering a theme of current interest (maximum of 10 thousand words).
Articles category and subjet area
The Journal of Nutrition does not assess studies that have already been presented in national or foreign events and/or translated into other languages in order to preserve the originality of the study
The list of authors, included below the title, should be limited to 6. The authorship credit must be based on substantial contributions, such as conception and design, or analysis and interpretation of the data. The inclusion of authors whose contribution does not include the criteria mentioned above is not justified. Individuals who made smaller contributions may be listed in the Acknowledgment section. The first page of the article must contain the main institutional affiliation and academic titles of each author.
Manuscript assessment will only begin after the inclusion of this information in the title page.
The identification page must also contain a paragraph clearly describing the contribution made by each author.
The authors may indicate three referees for assessing the manuscript and their respective e-mails and institutional affiliations. Alternatively, the authors may indicate three referees that should not assess their manuscript.
Manuscript Assessment Process
Original manuscripts will be accepted for assessment as long as they have not been submitted to any other journal and/or published in events to preserve the original character of the article. Manuscripts must contain a letter signed by all authors requesting the Journal to publish their manuscript.
All manuscripts will only start undergoing the publication process if they are in agreement with the Instructions to the Authors. If not, they will be returned for the authors to make the appropriate adjustments, include a letter or other documents that may be necessary. See item preparation of the manuscript.
Articles with any of the mistakes mentioned above will be returned even before they are submitted to assessment regarding the merit of the work and the convenience of its publication.
Pre-analysis: assessment is made by the Scientific Editors based on the originality, pertinence, academic quality, and relevance of the manuscript for the area of nutrition.
Manuscripts approved in this stage will be sent to ad hoc referees. Each manuscript will be sent to three referees of known competence in the theme. The authors may choose one of them. If there is disagreement, the manuscript will be sent to a fourth referee.
Articles with any of the mistakes mentioned above will be returned even before they are submitted to assessment regarding the merit of the work and the convenience of its publication.
The entire manuscript process will end on the second version, which will be final.
The peer review process used is the blind review, where the identity of the authors and the reviewers is not mutually known. Thus the authors must do everything possible to avoid the identification of the authors of the manuscript.
The opinions of the reviewers are one of the following: a) approved; b) new analysis needed; c) refused. The authors will always be informed of the reviewers' opinion.
The referees’ opinions will be analyzed by the associated editors, who will then suggest to the Scientific Editor whether the manuscript should be published. The Editor-in-Chief will make the final decision regarding the publication of the manuscript (Approved or Rejected).
Rejected manuscripts that can be reformulated may be submitted again as a new manuscript and undergo a new assessment process.
When changes are requested by the referees, the manuscript will be returned to the authors along with the referees’ opinions and suggestions. The authors have 30 (thirty) days to make the adjustments, respecting the Greenwich (London) time.
Accepted manuscripts: manuscripts accepted for publication may return to the authors for approval of eventual changes made during the editing and formatting processes, according to the Journal’s style.
Publication in English: if approved, the articles indicated by the Editorial Board will be published in English. For the manuscript to be published, the authors must provide the English translation of the version approved by the Journal. The translation is paid for by the authors.
In order to guarantee the quality and uniformity of the translated manuscripts, the manuscript must be translated by a highly trained translator with proven experience in the translation of scientific texts, indicated and certified by the Journal.
If the manuscript needs reviewing by one of the translators indicated by the Journal, the authors must follow the formatting instructions provided by e-mail by the Journal. The authors are responsible for verifying the entire translation (body of the text, illustrations, tables, charts, etc.).
Only spelling corrections or the substitution of one or another word and numerical data in the tables and graphs will be accepted. The inclusion and/or exclusion of sentences, paragraphs, images, and references will not be accepted. If something needs correcting, please do so as follows:
