Scope and policy
The Brazilian Journal of Nutrition is a specialized periodical that publishes articles that contribute to the study of Nutrition in its many sub-areas and interfaces. It is published bimonthly and open to contributions of the national and international scientific communities.
Submitted manuscripts may be rejected without detailed comments after initial review by at least two Brazilian Journal of Nutrition editors if the manuscripts are considered inappropriate or of insufficient scientific priority for publication in the Journal.
The Journal accepts unpublished articles in Portuguese, Spanish or English, with title, abstract and keywords in the original language and in English, in the following categories:
Original: contributions that aim to disclose the results of unpublished researches, taking into account the relevance of the theme, the scope and the knowledge generated for the research area (maximum limit of 5 thousand words).
Special: invited articles on current themes (maximum limit of 6 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 6 thousand words). There will be a maximum of two reviews per issue.
Communication: information reported on relevant themes and based on recent research, whose objective is to subsidize the work of professionals who work in the field, serving as a presentation or update on the theme (maximum limit of 4 thousand words).
Scientific note: partial unpublished data of an ongoing research (maximum limit of 4 thousand words).
Assay: works that can bring reflection and discussion of a subject that generates questioning and hypotheses for future research (maximum limit of 5 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
Authors should indicate the article's category and subject area, namely: food and social sciences, nutritional assessment, nutritional biochemistry, nutrition, nutrition education, epidemiology and statistics, micronutrients, clinical nutrition, experimental nutrition, nutrition and geriatrics, nutrition, maternal and infant nutrition in meal production, food and nutrition policies and health.
Research involving living beings
|Results of research involving human beings and animals, must contain a copy of the Research Ethics Committee approval.|
Registration of Clinical Trials
Articles with results of clinical researches must present an identification number in one of the Register of Clinical Trials validated by criteria established the the World Health Organization (WHO) and International Committee of Medical Journal Editors (ICMJE), whose addresses are available at the ICMJE site. The identification number must be included at the end of the abstract.
The authors must indicate three possible reviewers for the manuscript. Alternatively, the authors may indicate three reviewers to whom they do not want their manuscript to be sent.
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 manuscripts must explicitly contain in the identification page the contribution of each one of the authors.
Manuscript judgment process
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.
It is strongly recommended that the author(s) seek professional language services (reviewers and/or translators certified in the Portuguese or English languages) before they submit articles that may have semantic, grammar, syntactic, morphological, idiomatic or stylistic mistakes. The authors must also avoid using the first person of the singular, "my study...," or the first person of the plural "we noticed...," since scientific texts ask for an impersonal, non-judgmental discourse.
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-evaluation: Scientific Editors evaluate manuscripts according to their originality, application, academic quality and relevance in nutrition.
Once the articles are approved in this phase, they will be sent to ad hoc peer reviewers selected by the editors. Each manuscript will be sent to two reviewers of known competence in the selected theme. One of them may be chosen by the authors' indicatiton. If there is disagreement, the manuscript will be sent to a third reviewer.
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.
Reviews are examined by the Editors who will recommend or not the manuscripts approval by the Scientific Editor.
Rejected manuscripts that can potentially be reworked can be resubmitted as a new article and will undergo a new peer review process.
Conflict of interest
If there are conflicts of interest regarding the reviewers, the Editorial Committee will send the manuscript to another ad hoc reviewer.
Accepted manuscripts: accepted manuscripts may return to the authors for the approval of changes done in the editorial and normalization process, according to the Journal's style.
Proof sheets: the proof sheets will be sent to the authors for correction of printing mistakes. The proof sheets need to be sent back to the Editorial Center within the stipulated deadline. Other changes to the manuscript will not be accepted during this phase.
Preparation of the manuscript
Submission of works
Manuscripts need to be accompanied by a letter signed by all the authors describing the type of work and the thematic area, a declaration that the manuscript is being submitted only to the Journal of Nutrition, an agreement to transfer the copy rights and a letter stating the main contribution of the study to the area.
If the manuscript contains figures or tables that have already been published elsewhere, a document given by the original publisher authorizing their use must be included.
