Submit Your Research in These Areas:
Pre-Submission Checklist
Manuscript File Ready
Complete manuscript in Word (.doc/.docx) or LaTeX format. Include title page with all author names, affiliations, and corresponding author contact details (email, ORCID iD recommended).
Structured Abstract (250-300 words)
Include Background/Objectives, Methods (specify dietary assessment tools, study design, statistical analyses), Results (key nutritional findings with effect sizes), and Conclusions. For intervention trials, describe participant characteristics and primary outcomes.
Keywords (4-6 terms)
Use MeSH terms where applicable. Examples: "dietary intervention", "micronutrient deficiency", "nutritional biomarkers", "food frequency questionnaire", "nutrigenomics", "Mediterranean diet", "nutrition policy", "food environment", "health equity", "implementation science".
Figures and Tables
High-resolution figures (TIFF/EPS, 300 DPI minimum) showing dietary intake data, biomarker results, forest plots for meta-analyses, or metabolic pathway diagrams. Tables with nutritional composition, anthropometric measurements, or statistical results. All with descriptive captions.
Ethics Approval Documentation
For human nutrition studies: IRB/ethics committee approval number and informed consent statement. For animal studies: IACUC approval and adherence to ARRIVE guidelines. Include ethics approval letter if requested.
Clinical Trial Registration
For dietary intervention trials and nutrition RCTs: Provide trial registration number from ClinicalTrials.gov, WHO ICTRP, or equivalent registry. Registration must occur before participant enrollment.
Detailed Methods Section
Describe dietary assessment methods (24-hour recalls, FFQ, diet records), nutrient analysis software used, biomarker assays, statistical approaches, and sample size calculations. For intervention studies, detail the dietary protocol, compliance monitoring, and any blinding procedures used; for pragmatic or real-world interventions where blinding is not feasible, clearly describe measures taken to minimize bias.
Conflict of Interest Statement
Disclose any relationships with food industry sponsors, dietary supplement companies, nutrition product manufacturers, or relevant commercial entities. Include funding sources and role of sponsors in study design and data analysis.
References in Vancouver Style
Numbered citations in order of appearance. Include DOIs for all references where available. Ensure nutrition-specific journals and databases are properly cited.
Cover Letter
Address to Editor-in-Chief. Explain the novelty of your nutrition research, significance to the field, and why IJN is the ideal venue. Highlight how your work advances understanding of diet-health relationships or nutritional science methodology.
Nutrition-Specific Requirements
If your manuscript involves dietary supplements or functional foods, provide detailed composition information including bioactive compound concentrations. For dietary assessment studies, describe validation procedures for food frequency questionnaires or dietary recall methods. Include portion size references (e.g., food models, photographs) and specify nutrient calculation software used (e.g., Nutritionist Pro, NDSR, ESHA Food Processor).
For intervention trials, provide complete dietary protocols including meal plans, recipes, or supplement formulations. Describe compliance monitoring methods (e.g., food diaries, biomarkers, pill counts) and report adherence rates.
Reporting Guidelines
CONSORT Reporting for Clinical Trials
The International Journal of Nutrition requires all randomized controlled trials and other prospective intervention studies involving human participants to adhere to the CONSORT (Consolidated Standards of Reporting Trials) guidelines, including the CONSORT extension for cluster or pragmatic trials where applicable. Authors must submit a completed CONSORT checklist and a participant flow diagram at the time of initial submission, clearly indicating where each checklist item is addressed in the manuscript.
Manuscripts that do not follow CONSORT structure and content (e.g., clear description of randomization, allocation concealment, blinding, sample size calculation, and handling of missing data) may be returned to authors for revision prior to peer review. CONSORT documents should be uploaded as supplementary files during submission and will be made available to reviewers and, where appropriate, to readers.
STROBE Reporting for Observational Studies
For observational research, including cohort, case-control, and cross-sectional studies in nutrition, the International Journal of Nutrition requires adherence to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. Authors should structure their manuscripts to address key STROBE items such as study design, setting, participants, variables, data sources and measurement, bias, study size, statistical methods, and limitations.
A completed STROBE checklist indicating page numbers where each item is reported must be submitted with the manuscript as a supplementary file. Submissions that do not adequately address STROBE items may be returned for revision before peer review proceeds.
SAGER Guidelines for Sex and Gender Reporting
The International Journal of Nutrition expects authors to follow the SAGER (Sex and Gender Equity in Research) guidelines when designing, analyzing, and reporting studies involving human participants, animals, cells, or tissues. Authors should clearly state whether sex and/or gender were considered in the study design, describe how these variables were measured and analyzed, and report sex- and gender-disaggregated results where appropriate.
When sex or gender analyses are not conducted, authors must provide a brief justification in the Methods or Limitations section. Manuscripts that ignore relevant sex or gender dimensions without justification may be returned for revision. Editors and reviewers will assess compliance with SAGER recommendations as part of the evaluation of methodological rigor and interpretability.
Data and Code Availability
To promote transparency and reproducibility in nutrition research, the International Journal of Nutrition requires authors of empirical studies to provide a data availability statement in their manuscript. This statement should describe whether de-identified data, analytic code, and other materials are available; where they can be accessed (e.g., institutional repository, public data archive); and any conditions for access consistent with ethical and legal requirements.
Wherever possible, authors are encouraged to deposit de-identified datasets and analysis code in recognized repositories prior to publication and to include persistent identifiers (e.g., DOIs) in the manuscript. If data cannot be shared, authors must clearly explain the reasons (e.g., participant confidentiality, legal restrictions). Editors and reviewers may request access to data or code during peer review or post-publication. Suspected image manipulation may lead to rejection, correction, or retraction in line with publication ethics guidelines.
Image and Figure Integrity
The International Journal of Nutrition requires that all figures, images, and graphical data accurately represent the original findings without inappropriate manipulation. Adjustments to brightness, contrast, or color balance are permissible only if applied uniformly to the entire image and do not obscure, eliminate, or misrepresent any information.
Authors must not splice, rearrange, or selectively enhance images (e.g., gels, blots, microscopy) in ways that could mislead readers. Any necessary image composites must be clearly indicated in the figure and legend. Editors may request original, unprocessed image files during peer review or post-publication. Suspected image manipulation may lead to rejection, correction, or retraction in line with publication ethics guidelines.
Statistical Methods and Review
Manuscripts submitted to the International Journal of Nutrition must describe statistical methods in sufficient detail to allow replication, including model specifications, handling of missing data, adjustment for confounders, and approaches to multiple comparisons where relevant. Authors should justify their choice of statistical tests and provide information on sample size calculations for intervention and observational studies.
The editorial team may seek input from statistical reviewers for manuscripts with complex or novel analyses. Authors may be asked to provide analysis code, statistical output, or additional clarification during peer review. Submissions with inadequate or inappropriate statistical methods may be returned for revision or rejected on methodological grounds.
