The Journal of the Academy of Nutrition and Dietetics is the official research publication of the Academy of Nutrition and Dietetics. The purpose, expressed in the mission statement, is to be "the premier peer-reviewed journal in the field of food, nutrition, and dietetics." The Journal is published in both print and electronic formats and publishes Articles in Press (articles posted on the Journal's website before the print version).The Journal publishes manuscripts that advance knowledge across a wide range of research and practice issues in nutrition and dietetics. Evidence-based contributions of original research; focused meta-analyses of cohort and randomized clinical trials; systematic reviews; and innovative research applications are welcome. Topics include foods and nutrients and their implications in health and disease; dietary patterns and dietary interventions; nutritional science, nutrigenomics, and medical nutrition therapy; translational research; dietetics practice and public health; nutrition epidemiology and bio-statistical applications in nutrition research; food science and biotechnology; foodservice systems; leadership and management in food and nutrition systems and application to public policy; and medical nutrition and dietetics education. International contributions on global topics of nutrition interest are also welcome, providing there is relevance to the largely US readership and findings are placed within that context. Major trends that impact research and practice in the fields of food, nutrition, and dietetics may also be considered if placed in appropriate contexts for the Journal's readership (eg, population demographic transitions, environmental trends, health care advancements).
The Journal does not publish market research studies; studies that lack testable hypotheses or measureable objectives; studies that use un-validated scientific methods; sections from theses or dissertations unless systematic and rigorous in their design. The Journal does not publish animal studies, studies lacking scientific rigor and quality control, studies without a control group when indicated by study design, or studies with random findings or author opinions. Abstracts that were presented at a scientific meeting do not preclude a manuscript from consideration for publication.Manuscripts reporting survey data should have sufficient response rates and appropriate characterization of non-responders to ensure that nonresponse bias does not threaten the validity of the findings. For most surveys, such as those conducted by telephone, personal interviews, mail, e-mail, or via the web, authors are encouraged to report the survey outcome rates using standard definitions and metrics, such as those proposed by the American Association for Public Opinion Research. Clinical trials should be registered at the ClinicalTrials.gov. It is strongly encouraged that behavioral studies include a behavioral theory/framework.
The Academy of Nutrition and Dietetics offers an online toolkit designed to help authors understand and embrace nutrition research. The toolkit helps the reader, and potentially a new investigator or budding author, learn how to evaluate and use published research; the basics of conducting a research project; and how to interpret research articles effectively. It includes several "how to" modules, reference articles and is free to members of the Academy. The Journal's publisher, Elsevier, also offers information and a toolkit for authors on Ethics in Research and Publication.
The following publications have been developed by the Journal's Board of Editors' Statistics Team to further support Journal readers and authors in nutrition research.

Peer Review Process
The Journal conforms to guidelines of peer review as promulgated by the International Committee on Medical Journal Editors. Peer review for all articles undergoing review is double-blinded and reviewers are required to maintain confidentiality about the manuscripts they review and must not divulge any information about a specific manuscript or its content to any third party without prior permission from the Journal editors. The reviewers evaluate each manuscript on the basis of content, originality, scientific accuracy, clarity, and contribution to the field of nutrition and dietetics. The Journal's checklist system described in the article categories section will be used by peer reviewers to complete the review. Manuscripts are accepted at the discretion of the reviewers and the Journal editors. After peer review (usually 6 to 8 weeks after the date of submission), the corresponding author will be notified whether the manuscript has been accepted with revision or rejected.
These evidence-based manuscripts include hypothesis-driven, randomized controlled clinical trials; intervention studies; prospective cohort studies; case-control studies; comparative effectiveness research; epidemiologic assessments; other population-based observational studies with large sample sizes and representative of a population of interest; validated surveys with high response rates from verified participants; cost-effectiveness studies and decision analyses; and research on the validation of novel screening and diagnostic tests as well as unique dietary assessment methodologies. These reports are expected to utilize rigorous research designs with appropriate statistical analyses and validated research methods. Original Research manuscripts, in general, range between 3,500 and 5,000 words, not including abstract, tables/figures, or references. Figures and tables range from two to six and should be limited to those most pertinent to the study without duplicating findings in the text.
These evidence-based research articles are shorter reports of research findings that are typically hypothesis-driven and may include secondary and/or cross-sectional analyses from larger population-based studies; epidemiological and survey research with relatively large sample sizes representative of a population of interest; observational studies; randomized clinical trials using smaller sample sizes; pilot studies; case series investigations; and validation studies of established dietary or clinical assessment techniques in new populations. These reports are expected to utilize rigorous research designs with appropriate statistical analyses and validated research methods, although some of these reports may also be methodological validation studies. Brief articles are typically 2,500-3000 words, not including abstract, tables/figures, or references. Figures and tables range from one to three and should be limited to those most pertinent to the study without duplicating findings in the text.
All Original Research and Original Research: Brief articles are reports using one of the study designs listed below and are representative of a population of interest. Authors submitting to either of these two categories must select the appropriate study design and checklist. Links are provided below each study design and authors are strongly encouraged to review all the information provided in the corresponding link(s) prior to writing their manuscript. Authors are required to upload a copy of the checklist with their submission and indicate on the checklist the page and/or line number where the requested elements are located. The checklists are part of publicly available websites and are not unique to the Journal with the exception of the EAL and Narrative review checklists Peer reviewers will use the checklist as part of their review process. If elements from the checklist are missing or it is felt they are not applicable, a statement of explanation must accompany the manuscript regarding the reasons for the exclusion. Omission of the checklist may delay manuscript review.Original Research and Original Research: Brief manuscripts should include:
- structured abstract included as the first page of the manuscript body;
- introduction stating the purpose and relevance of the study and the testable hypotheses and/or measurable objectives underlying the study design;
- clear and full description of materials and methods, including criteria for participant selection and reasons for excluding any data or subjects, sample size computation or how sample size was determined, referenced measurement instruments and quality control measures, summary details of statistical methods, and for randomized clinical trials include method of randomization;
- report of the results following the same order presented in the methods for clarity;
- discussion of the results should be compared with other published data of a similar nature using current literature along with implications of the results for further research or possible clinical application. For example, what do the results mean for the topic being investigated? In addition, a paragraph describing the strengths and limitations of the study should be included;
- conclusions should be succinctly stated and drawn only from reported results. They should not go beyond or overstate them. Implications for further research might be included;
- current and relevant peer-reviewed scientific references; and
- tables/figures with clearly written titles, headings, and footnotes that permit full interpretation without accompanying text.
Please select the appropriate study design and review the information in the link(s) provided. Checklists will need to be copied from the site, completed with line and/or page information, and uploaded as a separate file along with the manuscript.Study Design and Checklists
- Observational (eg, Cross-Sectional, Case-Control, Cohort)
- Experimental (eg, Randomized Clinical Trial, Crossover Design)
- Cost-Effectiveness Analysis
These articles should address topics with an extensive body of primary source literature to provide a critical summary of the current evidence and applications using the appropriate software (eg, Cochrane, Comprehensive Meta-Analysis). In some cases, these articles may also address an emerging topic with limited literature to better demonstrate the need for more research. Systematic reviews that include meta-analyses are encouraged. Systematic Review manuscripts, in general, will range between 4,000-5,000 words, not including abstract, tables/figures, or references. Figures and tables range from two to six and should be limited to those most pertinent to the review without duplicating information in the text.
These articles answer a precise series of questions related to a specific food and nutrition topic. Through a predefined approach and criteria, objective and transparent methodology is used to judge food and nutrition-related science. Manuscripts are submitted by expert workgroup members who have evaluated, synthesized and graded the strength of the related science to support conclusions. Evidence Analysis Library Review manuscripts, in general, will range between 4,000-5,000 words, not including abstract, tables/figures, or references. Figures and tables may range up to six to eight and should be limited to those most pertinent to the review without duplicating information in the text. J Am Diet Assoc. 2010;110(12):1852-1889.
Narrative review manuscripts are unbiased reviews on specific nutrition topics with public health, clinical, management, or educational relevance. These review articles should address topics with an extensive body of primary source literature to provide a critical, balanced summary of the current evidence and applications. The data sources should be as current as possible, ideally with the search having been conducted within several months of manuscript submission. In some cases, Narrative Review articles may also address an emerging topic with limited literature to better demonstrate the need for more research. Narrative Review articles can range from 4,000-5,000 words and may include two to six tables or figures, as appropriate. J Acad Nutr Diet. 2013;113(3):416-430.
Specific guidelines in writing a Systematic Review include:
- Clearly define and clarify the topic being addressed.
- When presenting studies, organize by conceptual subheadings and themes rather than discussing one after another.
- Identify relations, contradictions, gaps and inconsistencies in the literature.
- Include specific questions left to answer with future research.
- Detail the process used in finding sources and screening the literature for the best studies.
- Describe the process for grading the literature, prioritizing studies by rigor of the study design and methodology.
- Present both pro and con sides of the literature base regarding a particular problem.
- If possible, summarize results from large numbers of publications in a table.
- Include practical recommendations for the practice of dietetics based on the reviewed literature.
Study Design and Checklists
- Systematic Review- Randomized Control Trials
- Systematic Review- Observational
- Checklist (see the Table)
- Evidence Analysis Library
- Narrative Review
Commentaries are scholarly papers that address topics of interest to the dietetics profession and often reflect matters of emerging importance or of a controversial nature that require additional research or policy development. Such topics may have been previously published in the Journal or foreshadow emerging science or practical applications. Commentaries may be invited or spontaneously submitted and should focus on matters of nutrition research, the practice of dietetics, or related areas with rigorous attention to matters of study design, the quality of existing data, and relevant limitations as well. Commentaries are approximately 2,500 words in length (excluding reference, tables/figures) and are expected to be balanced, unbiased, and well documented with quality references. Commentaries may include one or two tables or figures as appropriate, and should reflect a substantive area of concern. Subjective, anecdotal, or purely descriptive data are not publishable in this context. For an example of a Commentary, please refer to: J Acad Nutr Diet. 2012;112(9):1330-1333.
A Research Editorial is written in conjunction with an upcoming publication of an Original Research paper. Well-documented, evidence-based editorials on relevant subject matter of key interest to the readership are invited. Editorials are expected to contribute substantive evidence regarding the topic of specific interest, not simply descriptive or subjective material, nor a summary of the paper involved. These manuscripts average in length around 2,500 words (excluding references, tables and figures) and may include up to two tables and/or figures. For an example of a Research Editorial, please refer to: J Acad Nutr Diet. 2013;113:1153-1154.
These news- and information-driven articles offer authors an opportunity to discuss cutting-edge or emerging nutrition topics, scope of practice-related topics, emerging dietetics issues, current media topics, and prevalent client communication issues. Topics of Professional Interest articles are not research summaries or briefs. Particular areas of interest include:
- management in dietetics
- operations in all areas of practice (eg, sustainability within operations, outcomes assessment)
- media interest/what to tell patients/clients about hot topics (eg, allergies)
- foodservice, retail food service, and food safety and biosecurity
- standardized language
- quality measures and outcomes (eg, customer satisfaction)
- emerging areas of competency development (eg, cultural competency, leadership qualities/opportunities)
- job/career satisfaction and career path research
- human resource management in all areas of dietetics
Articles are expected to keep the registered dietitian nutritionist (RDN)/nutrition and dietetics technician, registered (NDTR) informed on health issues in nutrition that are becoming increasingly important to the profession. These manuscripts may range in length from 1,000 to 3,500 words, including references and can include up to four tables and/or figures. For an example of a Topics of Professional Interest article, please refer to: J Am Diet Assoc. 2011;111(3):340-353.Business of Dietetics
This section provides practical and how-to insights into the workings of the business field, such as resume writing, legal knowledge, career tips, professional economic issues, mentoring issues, and leadership training. These manuscripts average between 850 and 2,000 words and can include up to four tables and figures. For an example of a Business of Dietetics article, please refer to: J Acad Nutr Diet. 2012;112(11):1718-1723.
These articles focus on nutrition-related case studies and novel scientific or conceptual advancements within the field of dietetics that are vital to providing timely support for promising areas of future research and practice. Case studies should include: (1) an introduction and general description of the pathophysiology of the disease or disorder and its nutritional relevancy; (2) a brief but thorough description of the clinical case (eg, patient profile, presenting symptoms, relevant past medical/surgical history, hospital or treatment course, laboratory results, tests or procedures) with utilization of the Nutrition Care Process (J Am Diet Assoc. 2008;108(7):1113-1117) , International Dietetics and Nutrition Terminology (J Am Diet Assoc. 2008;108(8):1287-1293), and using de-identified data to protect the patient or patients' right to privacy; (3) the interventions and medical nutrition therapies and evidence-based guidelines employed; and (4) a discussion and conclusion, which includes outcome data (if available), lessons learned for the subsequent management of similar cases and emphasis on future directions for applicable research. These manuscripts can have a word count up to 2,000. For an example of a Case Study article, please refer to: J Acad Nutr Diet. 2013;113(2):213-218.
These brief articles communicate novel scientific or conceptual advancements within the field of dietetics that are vital to providing timely support for promising areas of future research and practice. As formal research manuscripts or briefs may not yet be fully developed, progress reports reflecting emerging science and innovative findings specific to dietetics issues are welcome to help keep food and nutrition practitioners apprised of important new developments in the field. Brief summaries should be written in a narrative format with specified subheadings that progress in a logical order: (1) introduction (succinctly summarizing in a few sentences the relevant science and the novelty of this new emerging area: Why is this new or innovative? What gap in research or practice does this attempt to address?); (2) body (describe the concept, idea, or new area of interest and how it is being tested: What technique, methods, or approach to the problem is applied? Briefly, in a few sentences, summarize the developmental process and/or improvements to previous versions, practices, or techniques: What is the new area/item? How is it different? How does understanding the new area/item enhance nutrition and dietetics?); (3) conclusions (describe future research implications or direct applications to the field of nutrition and dietetics-in a few sentences, explore the potential impact this is likely to have and offer website or other access to ongoing progress reports: How does this change future research, practice, or educations efforts?). These brief reports are typically around 800-1,200 words with up to one table or figure (optional) and only key references. For an example of an Emerging Science and Translational Applications article, please refer to: J Acad Nutr Diet. 2012;112(8):1134-1137.

The Journal follows the AMA Manual of Style, 10th ed, for references and citations. Number references consecutively in the order they are mentioned in the text. References should be cited in text, tables, and figures with superscript Arabic numerals. References cited only in a table or figure are acceptable if they are in sequence with references cited in the text. References should be typed double space on pages separate from the manuscript's main text. Reference management software, such as EndNote, or Reference Manager, is accepted. Note: Do not use the footnote function in Microsoft Word for references. Include references at the end of the manuscript.
Authors should use relevant, current citations from scientific peer reviewed literature. Peer reviewed scientific papers are papers published after they have been reviewed by other scientists, knowledgeable in the field of inquiry, to determine whether the studies they describe are of reasonable quality and the conclusions reported are supported by the evidence. References from nonscholarly publications are not acceptable; however, exceptions may be made based on the context in which the reference is included. Updated references (including access dates for website sources) are expected for manuscripts that have undergone a long turn-around time for review and/or revision. No matter how well known a book or source material (eg, Dietary Reference Intakes, Dietary Guidelines for Americans, MyPlate), it must be included in the list of references if it is mentioned in the manuscript. Avoid using abstracts or presentations as references; full reports, either published or in press, are preferred. Personal communications may not be cited as references but may be noted parenthetically in the text. All personal communications should be dated, and authors must secure the approval of the person quoted. Unpublished data, such as an article submitted for publication but not yet accepted, should be cited parenthetically in the text with the names of the authors, date, and the notation "unpublished data." Articles accepted for publication but not yet published can be included in the list of references with the notation "In press." Inclusive page numbers must be provided for all periodical articles cited. Page numbers are not required when an entire book is cited, but specific page numbers are needed when only a chapter or section of a book is cited. Provide a page number for all material quoted directly from any source. Authors are responsible for the accuracy and adequacy of all references cited in their manuscript.Example of Periodical Reference:
King DE, Mainous AG,3rd, Lambourne CA. Trends in dietary fiber intake in the United States, 1999-2008. J Acad Nutr Diet. 2012;112(5):642-648.

Tables and figures should be limited to those required to clarify an article. Each table or figure should be understandable by itself and not require the reader to refer to the text. Present data only once, either in tabular or graphic form or in the text. Each table and figure, with table/figure number and title/legend included, should be submitted on a separate attached page with the manuscript. Acceptable file types for figures are: TIFF, EPS, PDF, and Microsoft Office files (Word, PowerPoint, Excel). Tables should be submitted as Microsoft Word files. The preferred font type for tables and figures is 12 point Times New Roman. Spell out all acronyms and/or abbreviations within the body of the table/figure or cite and define with superscript footnoes (eg. a, b, c).
Tables should be double spaced and limited to one per page. Number tables consecutively (according to the order they are cited in the text) with Arabic numbers. Table titles should be detailed enough to stand alone from the manuscript text. For example, a table titled "Demographic characteristics of focus group participants" is not detailed enough to be understood apart from the text of the manuscript. A more descriptive title that would stand alone from the text would be "Demographics of a cohort of 35 African American women with type 2 diabetes mellitus participating in focus group data collection on initiative eating practices."
For numerals less than 1.00, insert a zero to the left of the decimal point (eg, 0.95). Use a hyphen to indicate ranges (eg, 75-100). Identify statistical measures of variations (eg, standard deviation or standard error of the mean). When the designation line at the left-hand side of a table (stub) requires two lines, values in that horizontal row should align with the second line of the designation. Align columns vertically on decimal points, hyphens, or "Â±". Use superscript letters to indicate footnotes (eg, a,b,c); however, use the standard * for P < 0.05, ** for P < 0.01, and *** for P < 0.001. The asterisks indicating P values are only needed if the P values are not provided in the table. Cite and define all acronyms or abbreviations used in the table as superscript footnotes (eg, a, b, c). Footnote order is determined by the first appearance of footnoted material in a horizontal row.Authors who incorporate data from another published or unpublished source in a table must cite the original source in a reference or footnote. If a table is reproduced in its entirety, revised, modified, or adapted from another published source authors must obtain permission from the copyright holder of the table and indicate in a table footnote the source of the original table.
Authors should submit figures as separate attached documents when submitting a manuscript online. Bar graphs are used to show proportions or percents within categories, and line graphs are used to show data that are related such as serial observations. Three-dimensional figures are appropriate for simultaneous display of three but not two proportions or percents within categories (eg, height, weight, and percent body weight). Number figures consecutively (according to the order they are cited in the text) with Arabic numbers and supply a brief legend for each.
A figure legend should be brief yet make an illustration fully intelligible by itself. Cite and define all acronyms or abbreviations used in the figure in the legend as superscript footnotes (eg, a, b, c).If a figure is reproduced in its entirety, revised, modified, or adapted from another published source, the authors must obtain permission from the copyright holder of the figure and indicate in the figure legend the source of the original figure.
Including Practice Implications with a manuscript submission is voluntary. Practice Implications is designed for authors of Original Research and Systematic Reviews to convey the core findings of their research and the potential bridge it provides to dietetics practice. Authors should briefly answer the following three questions for Practice Implications:
- What is the current knowledge on this topic?
- How does this research add to knowledge on this topic?
- How might this knowledge impact current dietetics practice?
Authors may acknowledge persons other than coauthors who have made substantial contributions to the development of their study or manuscript. Permission from all persons named in the acknowledgments must be obtained prior to submission to the Journal and authors must inform the Editor-in-Chief in writing that such permission has been obtained. This statement can be included in the "Comments" section in EES when submitting a manuscript.

Authors' rights are explicitly detailed on the copyright form and on the Author Rights section of Elsevier's website.The Transfer of Copyright, Authorship Agreement, and Conflict of Interest Form can be submitted via EES, emailed to firstname.lastname@example.org, or sent via mail to Lois Ahrens RDN, LD, Journal of the Academy of Nutrition and Dietetics, University of Iowa, 200 Hawkins Drive E257 GH, Iowa City, IA 52242.
In addition to the Transfer of Copyright, Authorship Agreement, and Conflict of Interest Form, all financial and material support for the research and the work should be clearly and completely identified and submitted in EES as a separate attached page with the manuscript. If there is no funding or support, a page should be attached stating as such. Inclusion of an external Data Safety and Monitoring Board is strongly recommended for all industry-sponsored research.
A conflict of interest may exist when an author (or the author's institution or employer) has financial or personal relationships or affiliations that could influence (or bias) the author's decisions, work, or manuscript. All authors are required to disclose all potential conflicts of interest, including specific financial interests and relationships and affiliations (other than those affiliations listed in the author page of the manuscript) relevant to the subject of their manuscript. Authors should err on the side of full disclosure and should contact the editorial office if they have questions or concerns.
In addition to the Transfer of Copyright, Authorship Agreement, and Conflict of Interest Form, all such disclosures must be submitted in EES as a separate, unsigned, attached page with the manuscript. Authors without conflicts of interest, including specific financial interests and relationships and affiliations relevant to the subject of their manuscript, should include an unsigned statement of no such interests along with their manuscript. Failure to include this information in the manuscript may delay the review of the manuscript.Authors are expected to provide detailed information about all relevant financial interests and relationships or financial conflicts within the past 5 years and for the foreseeable future (including, but not limited to employment/ affiliation, grants or funding, consultancies, honoraria, speakers' bureaus, stock ownership or options, expert testimony, royalties, or patents filed, received, pending, or in preparation), particularly those present at the time the research was conducted and through publication, as well as other financial interests (such as patent applications in preparation), that represent potential future financial gain. Although many universities and other institutions have established policies and thresholds for reporting financial interests and other conflicts of interest, the Journal of the Academy of Nutrition and Dietetics requires complete disclosure of all relevant financial relationships and potential financial conflicts of interest, regardless of amount or value. If authors are uncertain about what constitutes a relevant financial interest or relationship, they should contact the editorial office.
For all accepted manuscripts, each author's disclosures of conflicts of interest and relevant financial interests and affiliations and declarations of no such interests will be published. Decisions about whether such information provided by authors should be published, and thereby disclosed to readers, are usually straightforward. Although editors are willing to discuss disclosure of specific conflicts of interest with authors, the Journal's policy is one of complete disclosure of all potential conflicts of interest, including specific financial interests and relationships and affiliations (other than those affiliations listed in the author page of the manuscript) relevant to the subject of their manuscript. If an author's disclosure of potential conflicts of interest is determined to be inaccurate or incomplete after publication, a correction will be published to rectify the original published disclosure statement, and additional action may be taken as necessary, as outlined by and in compliance with the Committee on Publication Ethics.
Manuscript content and accuracy are the authors' responsibility.
Permission to Reprint
Any direct quotations, figures, or tables that have appeared in copyrighted material must be accompanied by written permission for their use from the copyright owner, along with full source information. Images of brand name products must have written consent from the manufacturer to be reproduced. Any photographs of identifiable persons must be accompanied by signed releases showing informed consent. Since articles appear in both the print and online versions of the Journal, the permission must specify "permission to publish in all forms and media." Failure to obtain print and electronic permission may result in the image or information not appearing in the print and/or online version.
In instances where plagiarism is suspected, the Journal follows the protocol set forth by the Committee on Publication Ethics.
The Journal does not ordinarily have publication charges for authors. However, authors can opt to make articles open access for a fee of $2,500 payable by the author or research funder to cover the costs associated with publication, unless otherwise specified by our publisher's agreement with your funding body. For information about funding body agreements and policies or other mandates that may apply visit the Funding Body Agreements section of Elsevier's website. Authors will be prompted to indicate whether they intend to publish as open access upon submission of their manuscripts. Authors' publication choice has no effect on the peer review process or acceptance of manuscripts.
Software developers are cited parenthetically in the text after the first mention of a software package. Software citations should include the name, version number, and release date of the software as well as the name of the software developer. [Example: All statistical analyses were conducted using SAS (version 9.1.3, 2006, SAS Institute Inc).] If software incorporates a nutrient database, provide information in the text about the database. This should include the release date for the database, a description of substantial modifications made to the database, and an explanation of how missing nutrient data for foods were handled (ie, indicate whether values were extrapolated and evaluate the effect of any missing values on dietary totals for the nutrients of interest). Do not include information about software or databases in the list of references or the abstract.
Footnotes should be kept to a minimum and indicated consecutively, with superscript symbols (*, †, ‡, §, etc), throughout the text. Double space footnotes on a separate sheet of paper. Footnote citations should read from top left to bottom right. All text in the footnote section of a table should be properly cited in the table. All abbreviations and acronyms in a table or figure must also be footnoted with the correct expansion.
Use of NCP and NCPT
For topics that are addressing dietetics and nutrition care provided by dietetics practitioners, authors should use the Nutrition Care Process (NCP) as a framework for describing the nutrition assessment, nutrition diagnoses, nutrition intervention, and nutrition monitoring/evaluation that was included in the research and use the Nutrition Care Process Terminology (NCPT) to describe the aspects of care within each of the above steps. Additional information on the NCP and NCPT is available under "Resources for Health Practitioners" on the Academy's website.
Bylines are a general indicator for indexing purposes of authors' contribution to the published work. Journal style is to list the highest academic degree(s) of each author followed by any/all credentials and certifications from the Commission on Dietetic Registration (eg, RD, RDN, DTR, CSP, CSR, CSG, CSO, CSSD, FAND); and if desired by the author, state licensure (LD, LDN, or CDN) and fellowships. If an author has a doctorate, master's level degrees should not be included unless the master's degree is in a different or specialized field. Academic degrees below the master's level are omitted unless they are the highest obtained degree. For credentials issued outside the United States, indicate the country of origin in a footnote.
Note: For articles that relate to specialist or advanced practice credentials, which appear in the "From the Academy" section, some author credentials may relate to specialist or advanced practice credentials obtained from another organization, and these can be included in the author byline. Non-CDR credentials received by the RDN/DTR author in these "From the Academy" articles will be verified by the Quality Management Team (for SOP/SOPP in focused areas of practice) or the HOD Governance Team (for Academy of Nutrition and Dietetics position or practice papers). These credentials include: CDE, BC-ADM, CNSS/CNSD, CHES, CLC, SNS, and others, which authors may inquire about at the time of submission. Authors from other fields such as nursing, medicine, surgery, etc., are asked to provide verification at the time of submission regarding their advanced practice credentials (these include, but are not limited to APRN-BC, CIC, NP, OCN, RM(C), RPh-BC-ADM).
Numbers below 10 are spelled out unless followed by a unit of measure or a percentage. Express all numbers 10 or larger as Arabic numerals. Numbers that begin a sentence are always spelled out. The number of significant digits reported should be realistic and supported by the original data (eg, 2,125 kcal, not 2,124.8 kcal; 105 lb, not 105.734 lb). For sample sizes smaller than 100, frequency must be given (eg, two of seven, not 29%); percent may also be provided if necessary. Also, do not include a decimal and zero after a whole percent number (Correct: 72%, Incorrect: 72.0%).
Abbreviate units of measure when used with numerals (5 g, 1,000 kcal). Chemical formulas should be written out, unless they are used to economize space in the column headings of a table; however, the formulas should be expanded in the footnotes. Always provide the complete form of an acronym the first time it is mentioned in the text (note that if an abbreviation has been spelled out in the abstract, it still must be spelled out in the text on first-time use). An acronym or abbreviation is permitted if it is used three or more times within the manuscript text. Avoid excessive use of acronyms and abbreviations. Avoid author-invented abbreviations and acronyms.
All clinical laboratory values must be expressed in Conventional Units, (eg, lipids should be expressed in mg/dL) with SystÃ¨me International (SI) units in parentheses in the manuscript text, for example: triglycerides 100 mg/dL (1.13 mmol/L). Authors must provide the conversion factor to SI units as a footnote in tables and figures. The exception to this is the use of kilocalories; the Journal will continue to use kilocalories instead of kilojoules. The metric system is preferred for the expression of length, area, mass, and volume. A table of normal values in both Conventional and SI units and the appropriate conversion factors appears on Oxford University Press website. Authors should refer to this table when converting data and use it as a guide for choosing the appropriate number of significant digits.
When specific products used in the research are referred to by a trade name, give the manufacturer's name parenthetically after the first mention. When possible use generic names for food and drugs. Registration or trademarks are not required.
Dietary Reference Intakes
Authors must use the Dietary Reference Intakes (DRIs), not the 1989 Recommended Dietary Allowances. Information on the DRIs can be found through the Institute of Medicine. If for any reason an author wishes to report nutrient intakes without using the stated DRIs, intakes may be reported, but adequacy should not be assessed.
Personal pronouns (eg, I, our, we) should be used sparingly, if at all, in Journal submissions except Letters to the Editor.
Race and Ethnicity
The Journal follows the guidelines set forth by the National Institutes of Health.
EDITORIAL PROCESSING AND PUBLICATION
Article content is the authors' responsibility. Accepted manuscripts are copyedited to conform to Journal style and to meet space limitations. Authors should note that the editing process is separate from and occurs after the peer-review process. The corresponding author will receive an electronic proof of the article and have an opportunity to review editorial changes and to double-check accuracy of content, tables, and statistics before publication. However, a change made by copyeditors for style, grammar, and readability should not be altered by authors unless a scientific error has been introduced. Authors will be expected to review galleys promptly (within 4 business days of receipt). If the corresponding author is not available to receive or review proofs at any given time, a back-up should be identified and contact information provided to the editors.
Embargo Policy/Articles in Press
For the protection of each author's work, the Journal does not allow the unauthorized pre-publication of any materials slated for publication. All articles accepted for publication are posted online in their corrected format as Articles in Press, and are subject to embargo until such date the articles are available online. The timetable for online publication is approximately 8 weeks from acceptance.
Authors wanting to coordinate press activity with their institutions should consult the contact provided in their proof communication to confirm embargo information.Translation Services
