Submission

This journal uses ScholarOne Manuscripts for online submission and peer review. Authors must first complete and submit a review proposal form through the online submission system. If you have been asked to write a proposal by a member of the Editorial Board, please indicate this on the form. The proposal will be reviewed by the Editorial Board, and if accepted, only then will you be invited to submit a full manuscript.

Scope

Nutrition Research Reviews (NRR) is an international journal that publishes comprehensive and challenging review articles on selected key topics in nutritional science. Authors are encouraged to take a critical approach in appraising the literature while also aiming to advance new concepts and hypotheses. NRR publishes both solicited and unsolicited articles.

Article types

NRR publishes critical, narrative review articles on key topics in nutritional science. 

NRR now also accepts substantive systematic reviews; a systematic review is a review of the evidence on a clearly formulated question that uses systematic and explicit methods to identify, select and critically appraise relevant primary research, and to extract and analyze data from the studies that are included in the review.

NRR considers a substantive systematic review to be one which covers a broad area to answer a key question and includes in the final analysis a good number of papers (>15) with a range of study designs that can include human, animal and in vitro models.

Publishing Ethics

NRR adheres to the Committee on Publication Ethics (COPE) guidelines on research and publications ethics. The Journal considers all manuscripts on the strict condition that:

1. The manuscript is your own original work, and does not duplicate any other previously published work;

2. The manuscript has been submitted only to the journal - it is not under consideration or peer review or accepted for publication or in press or published elsewhere;

3. All listed authors know of and agree to the manuscript being submitted to the journal; and

4. The manuscript contains nothing that is abusive, defamatory, fraudulent, illegal, libellous, or obscene.

Text taken directly or closely paraphrased from earlier published work that has not been acknowledged or referenced will be considered plagiarism. Submitted manuscripts in which such text is identified will be withdrawn from the editorial process. Any concerns raised about possible plagiarism or other violations of ethical guidelines in an article submitted to or published in NRR will be investigated fully and dealt with in accordance with the COPE guidelines.

The Nutrition Society, as the owner of NRR, endorses the Publication Ethics outlined by Cambridge University Press.

Authorship

The Journal conforms to the International Committee of Medical Journal Editors (ICMJE) definition of authorship. Authorship credit should be based on:

1. Substantial contributions to conception and design, data acquisition, analysis and/or interpretation; and
2. Drafting the article or revising it critically for important intellectual content; and
3. Final approval of the version to be published; and
4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

The contribution of individuals who were involved in the review but do not meet these criteria should be described in the Acknowledgments section.

Policy on prior publication

When authors submit manuscripts to this journal, these manuscripts should not be under consideration, accepted for publication or in press within a different journal, book or similar entity, unless explicit permission or agreement has been sought from all entities involved. However, deposition of a preprint on the author’s personal website, in an institutional repository, or in a preprint archive shall not be viewed as prior or duplicate publication. Authors should follow the Cambridge University Press Preprint Policy regarding preprint archives and maintaining the version of record. 

Detailed Manuscript Preparation Instructions

The below guidelines apply to full manuscripts submitted after acceptance of a review proposal form.

Language

Papers submitted for publication must be written in English and should be as concise as possible. We recommend that authors have their manuscript checked by an English language native speaker before submission, to ensure that submissions are judged at peer review exclusively on academic merit.

We list a number of third-party services specialising in language editing and / or translation, and suggest that authors contact as appropriate. Use of any of these services is voluntary, and at the author's own expense. Use of these services does not guarantee that the manuscript will be accepted for publication, nor does it restrict the author to submitting to a Cambridge-published journal. 

Spelling should generally be that of the Concise Oxford Dictionary (1995), 9th ed. Oxford: Clarendon Press. Authors are advised to consult a current issue of the journal in order to make themselves familiar with NRR as to typographical and other conventions, layout of tables etc.

Manuscript Format

The requirements of NRR are in accordance with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals produced by the ICMJE, and authors are encouraged to consult the latest guidelines, which contain useful, general information about preparing scientific papers.

Typescripts should be prepared with 1.5 line spacing and wide margins (2 cm), the preferred font being Times New Roman size 12. At the ends of lines, words should not be hyphenated unless hyphens are to be printed. Line numbering and page numbering are required.

For detailed instructions regarding statistical analysis and nomenclature requirements, please refer to the Appendix to these instructions.

Cover Letter

When invited to submit a full manuscript, authors are also invited to include a cover letter including a brief summary of the review. The text for the cover letter should be entered in the appropriate box as part of the online submission process.

Manuscripts should be organised as follows, with further sub-divisions depending on the nature of the review:

Title Page

The title page should include:

1. 1. The title of the article;
2. 2. Authors' names*;
3. 3. Name and address of department(s) and institution(s) to which the work should be attributed for each author;
4. 4. Name, mailing address, email address, telephone and fax numbers of the author responsible for correspondence about the manuscript;
5. 5. A shortened version of the title, not exceeding 45 characters (including letters and spaces) in length;
6. 6. At least four keywords or phrases (each containing up to three words).

Authors' names should be given without titles or degrees and one forename may be given in full. Identify each author's institution by a superscript number (e.g. A.B. Smith¹) and list the institutions underneath and after the final author.

Abstract

Each paper must open with an abstract of not more than 250 words. The abstract should be a single paragraph of continuous text outlining the aims of the work, the approach taken, the principal findings and the conclusions and their relevance to nutritional science.

Graphical abstract

A graphical abstract is a single image that summarises the main findings of a paper, allowing readers to gain quickly an overview and understanding of your work. Well-designed and prepared graphical abstracts are an important way to publicise your research, attracting readers, and helping to disseminate your work to a wider audience. Ideally, the graphical abstract should be created independently of the figures already in the paper but it could include a (simplified version of) an existing figure. Graphical abstracts are displayed at article level, and on the article landing page online. Submission of a graphical abstract is not mandatory but we welcome authors to submit one alongside their paper.

The graphical abstract should be submitted separately from the main paper using the ‘Graphical Abstract’ file designation on ScholarOne at revised submission stage. Graphical abstracts should be clear and easy for the viewer to read, and should illustrate one main point only. Permission to reuse images should be sought by the authors before submitting a graphical abstract.

We recommend that only TIFF, EPS or PDF formats are used for electronic artwork. Other non-preferred but usable formats are JPG, PPT and GIF files and images created in Microsoft Word. For further information about how to prepare your figures, including sizing and resolution requirements, please see our artwork guide. The image will be scaled to fit the appropriate space on Cambridge Core, so please ensure that any font used is clear to read, and that any text is included as part of the image file (although text should ideally be kept to a minimum). There is also no need to include the title ‘Graphical Abstract’ in your image.

Introduction

It is not necessary to introduce a paper with a full account of the relevant literature, but the introduction should indicate briefly the nature of the question asked and the reasons for asking it.

Main Body

The main body of the text should use appropriate headings and subheadings to break up the text and guide the reader. Manuscripts should end with a summary of the overall conclusions.

Acknowledgments

Here you may acknowledge individuals or organizations that provided advice and/or support (non-financial). Formal financial support and funding should be listed in the following section.

Financial Support

Please provide details of the sources of financial support for all authors, including grant numbers. For example, "This work was supported by the Medical research Council (grant number XXXXXXX)". Multiple grant numbers should be separated by a comma and space, and where research was funded by more than one agency the different agencies should be separated by a semi-colon, with "and" before the final funder. Grants held by different authors should be identified as belonging to individual authors by the authors' initials. For example, "This work was supported by the Wellcome Trust (A.B., grant numbers XXXX, YYYY), (C.D., grant number ZZZZ); the Natural Environment Research Council (E.F., grant number FFFF); and the National Institutes of Health (A.B., grant number GGGG), (E.F., grant number HHHH)".

Where no specific funding has been provided for research, please provide the following statement: "This research received no specific grant from any funding agency, commercial or not-for-profit sectors."

In addition to the source of financial support, please state whether the funder contributed to any aspect of the review, including interpretation of findings or the preparation of the manuscript. If the funder made no such contribution, please provide the following statement: "[Funder's name] had no role in the design, analysis or writing of this article."

Declaration of Interests

All authors must include a declaration of interests in their main manuscript file. This declaration will be subject to editorial review and may be published in the article. 

Interests which should be declared are situations that could be perceived to exert an undue influence on the content or publication of an author’s work. They may include, but are not limited to, financial, professional, contractual or personal relationships or situations. 

If the manuscript has multiple authors, the author submitting must include interest declarations relevant to all contributing authors. 

Example wording for a declaration is as follows: “Declaration of interests: Author 1 is employed at organisation A, Author 2 is on the Board of company B and is a member of organisation C. Author 3 has received grants from company D.” If no interests exist, the declaration should state “Declaration of interests: The author(s) declare none”. 

Authorship

Please provide a very brief description of the contribution of each author to the review. Their roles in planning and writing the article should be made plain.

References

References should be numbered consecutively in the order in which they first appear in the text using superscript Arabic numerals in parentheses, e.g. 'The conceptual difficulty of this approach has recently been highlighted^(1,2)'. If a reference is cited more than once, the same number should be used each time. References cited only in tables and figure legends should be numbered in sequence from the last number used in the text and in the order of mention of the individual tables and figures in the text.

Names and initials of authors of unpublished work should be given in the text as 'unpublished results' and not included in the References. References that have been published online only but not yet in an issue should include the online publication date and the Digital Object Identifier (doi) reference, as per the example below.

At the end of the paper, on a page(s) separate from the text, references should be listed in numerical order using the Vancouver system. When an article has more than three authors only the names of the first three authors should be given followed by 'et al.' The issue number should be omitted if there is continuous pagination throughout a volume. Titles of journals should appear in their abbreviated form using the NCBI LinkOut page. References to books and monographs should include the town of publication and the number of the edition to which reference is made. References to material available on websites should follow a similar style, with the full URL included at the end of the reference, as well as the date of the version cited and the date of access.

Examples of correct forms of references are given below.

Figures

Figures should be supplied as separate electronic files. Figure legends should be grouped in a section at the end of the manuscript text. Each figure should be clearly marked with its number and separate panels within figures should be clearly marked (a), (b), (c) etc. so that they are easily identifiable when the article and figure files are merged for review. Each figure, with its legend, should be comprehensible without reference to the text and should include definitions of abbreviations.

We recommend that only TIFF, EPS or PDF formats are used for electronic artwork. For further information about how to prepare your figures, including sizing and resolution requirements, please see our artwork guide.

In curves presenting experimental results the determined points should be clearly shown, the symbols used being, in order of preference, ○, ●, ∆, ▲, □, ■, ×, +. Curves and symbols should not extend beyond the experimental points. Scale-marks on the axes should be on the inner side of each axis and should extend beyond the last experimental point. Ensure that lines and symbols used in graphs and shading used in histograms are large enough to be easily identified when the figure size is reduced to fit the page.

Images submitted with a manuscript should be minimally processed; some image processing is acceptable (and may be unavoidable), but the final image must accurately represent the original data. Grouping or cropping of images must be identified in the legend and indicated by clear demarcation. Adjustment of brightness, contrast or colour balance is acceptable if applied to the whole image and to controls and if data do not disappear as the result of the manipulation. Authors should provide sufficient detail of image-gathering procedures and process manipulation in the Methods sections to enable the accuracy of image presentation to be assessed. Authors should retain their original data, as Editors may request them for comparison during manuscript review. If such data are unavailable the manuscript may be withdrawn from the review process. If a concern is raised about possible image manipulation in an article published in NRR, this will be investigated fully and dealt with in accordance with the Committee on Publication Ethics guidelines.

Tables

Tables should be placed in the main manuscript file at the end of the document, not within the main text. Be sure that each table is cited in the text. Tables should carry headings describing their content and should be comprehensible without reference to the text. Tables should not be subdivided by ruled lines.

The dimensions of the values, e.g. mg/kg, should be given at the top of each column. Separate columns should be used for measures of variance (SD, SE etc.), the ± sign should not be used. The number of decimal places used should be standardized; for whole numbers 1.0, 2.0 etc. should be used. Shortened forms of the words weight (wt) height (ht) and experiment (Expt) may be used to save space in tables, but only Expt (when referring to a specified experiment, e.g. Expt 1) is acceptable in the heading.

Footnotes are given in the following order: (1) abbreviations, (2) superscript letters, (3) symbols. Abbreviations are given in the format: RS, resistant starch. Abbreviations in tables must be defined in footnotes in the order that they appear in the table (reading from left to right across the table, then down each column). Symbols for footnotes should be used in the sequence: *†‡§||¶, then ** etc. (omit * or †, or both, from the sequence if they are used to indicate levels of significance).

For indicating statistical significance, superscript letters or symbols may be used. Superscript letters are useful where comparisons are within a row or column and the level of significance is uniform, e.g. '^a,b,cMean values within a column with unlike superscript letters were significantly different (P<0•05)'. Symbols are useful for indicating significant differences between rows or columns, especially where different levels of significance are found, e.g. 'Mean values were significantly different from those of the control group: *P<0•05, **P<0•01, ***P<0•001'. The symbols used for P values in the tables must be consistent.

Supplementary Material

Material that is not essential to understanding or supporting a manuscript, but which may nonetheless be relevant or interesting to readers, may be submitted as supplementary material. Supplementary material will be published online alongside your article, but will not be published in the pages of the journal. Types of supplementary material may include, but are not limited to, appendices, additional tables or figures, datasets, videos, and sound files.

Although Supplementary Material is peer reviewed, it is not checked, copyedited or typeset after acceptance and it is loaded onto the journal's website exactly as supplied. Please see our general guidance on supplementary materials for further information.

Where relevant we encourage authors to publish additional qualitative or quantitative research outputs in an appropriate repository, and cite these in manuscripts.
