GENERAL
Manuscripts for The Journal of Nutrition must be based on original, unpublished research and will be peer reviewed. Submission implies that the data have not been published (other than in abstracts), are not under consideration by another journal, and will not be released before publication.
Regional correspondents, whose role is to assist authors outside the United States, are listed with the editorial staff at the front of The Journal. If requested by authors, they will review manuscripts for appropriateness, scientific merit, methodology, form, and use of English. Acceptance for publication will be subsequently determined by the usual peer review and editorial processes.
The Journal publishes receipt date, date of completion of the initial review, and date of acceptance of the revised manuscript for each research article. Manuscripts not revised and returned within 120 days will be treated as new submissions. The date of acceptance will be the date when all requested revisions have been returned to the editorial office.
TYPES OF MANUSCRIPTS
Research articles.
Reports of original research of interest to the general community of nutritional scientists will be published as research articles. Studies of the biochemical and molecular action of nutrients, nutrient-gene interaction, nutrient metabolism, nutrient requirements, interactions and toxicity, human nutrition and metabolism, community and international nutrition, nutritional epidemiology, nutritional neurosciences, nutrition and aging, and methodological developments will be considered.
Research communications.
Manuscripts that concisely describe the results of studies that are complete but limited in scope will be published as research communications. These manuscripts will be limited to four Journal pages and will have a special format available from the editorial office or under publications at http://www.faseb.org/asns.
Reviews.
Most reviews published in The Journal of Nutrition will be part of a series entitled "Recent Advances in Nutritional Sciences" in response to invitations by the editor. These reviews will be published in a four-page format and will provide a recent rather than historical review of the subject matter. More comprehensive reviews and commentaries will be published as "critical reviews."
Issues and opinions.
Short essays presenting scientific viewpoints on issues in nutrition and limited to three Journal pages may be submitted.
Letters to the editor.
Comments on recently published Journal of Nutrition articles and other issues will be considered. Both the letter and the reply, including references, are limited to one Journal page and will be reviewed prior to acceptance.
Biographies and historical perspectives.
These manuscripts are invited by the biographical or historical editor. Suggestions of subjects and authors are welcomed by the editor.
Other.
Extensive reports of research, monographs, compendia, proceedings of symposia, etc., will be reviewed and considered for publication in The Journal or as a separately bound supplement. Initial contact and arrangements to cover the cost of publication should be made with the American Society for Nutritional Sciences (ASNS) headquarters.

As publisher of The Journal of Nutrition, the ASNS holds the copyright on all Journal articles. The 1978 copyright law requires that specific copyright transfer be obtained from all authors of each manuscript. Transfer of copyright forms that can be photocopied are printed in the January issue of The Journal. An original signature is required from each author. Copies of the completed form may be signed by each author independently, if necessary. All signed transfer of copyright forms should be included when manuscripts are submitted.
MANUSCRIPT PREPARATION
Papers should be completely double-spaced with numbered lines and
submitted in the format indicated below. Authors should consider
papers published in recent issues of The Journal of
Nutrition as models and should consult the CBE Style Manual
(Huth, 1994
). Specific items to include in
manuscripts are:
Title page.
Include a title which is a declarative statement of key findings and
which includes the species studied and footnotes to the title
(financial support of the research and previous publication or
presentation of data). List all authors (first name, middle initial,
last name) including their departmental and institutional addresses.
Indicate which authors are associated with which institutions by
footnotes. Identify a corresponding author and provide a complete
mailing address, telephone, fax, and e-mail address. Provide a running
title of 
48 characters.
Abstract page.
The abstract must be a single paragraph of no more than 250 words summarizing the relevant problem addressed by the study and the theory or hypothesis that guided the research. The abstract should include the study design/methodology and a clear statement of the results and conclusions. Three to five key words for indexing purposes must be listed at the end of the abstract.
Introduction.
Background to the research conducted and specific objectives should be clearly indicated.
Materials and methods.
Documentation of methods and materials used should be sufficient to permit replication of the research. State the source of specialized materials, diets, chemicals, and instruments and other equipment, with model or catalog numbers, where appropriate. Specify kits, analyzers, and commercial laboratories used. Describe modifications of standard assays. Include the name, city, and state or country of the supplier parenthetically in the text.
Human and animal research.
Reports of human studies must include a statement that the
protocol was approved by the appropriate institutional committee or
that it complied with the Helsinki Declaration as revised in 1983.
Research on animals should include a statement that the protocol was
approved by the appropriate committee or complied with the Guide for
the Care and Use of Laboratory Animals (NRC 1985
).
Describe how animals were killed. Describe control and experimental
subjects giving age, weight, sex, race, and for animals, breed or
strain. Give the name, city, and state or country of the suppliers of
experimental animals.
Diets.
Composition of control and experimental diets must be presented. When a
diet composition is published for the first time in The Journal
of Nutrition, utilize a table or a footnote to provide complete
information on all components. If previously described in The
Journal, a literature citation may be used. The proximate
composition of closed formula diets should be given as amounts of
protein, energy, fat, and fiber. Components should be expressed as g/kg
diet or µmol/kg diet rather than as percentages. For a discussion of
the formulation of purified animal diets, refer to Baker (1987)
and to a series of ASNS publications (AIN 1977
, AIN 1980
, AIN 1987a
, and AIN 1993
).
Statistical methods.
Describe all statistical tests utilized and indicate the probability level (P) at which differences were considered significant. Indicate whether data were transformed before analysis. Specify any statistical computer programs used.
Present the results of the statistical analysis of data in tables and
figures in the body or use superscripts to indicate significant
differences and define the superscripts in a table footnote or the
figure legend. Provide the appropriate statistics of variability. An
estimate of the error variance (SD or SEM) of group means should be
displayed in figures. Standard ANOVA methodology assumes a homogeneous
variance. If error variance is tested and found to be heterogeneous,
data should be transformed before ANOVA, or nonparametric tests should
be used. For a discussion of variability calculations and curve-fitting
procedures, see Baker (1986)
.
Units of measure.
Most measurements should conform to le Système
Internationale d’Unités (SI) (Young 1987
). The
metric system and the Celsius scale (°C) must be used. Concentrations
should be expressed on a molar basis. Except for diet composition,
convert to substance concentration, e.g., mol/L. The denominator should
be L. Do not use M, mM, N, etc. Use one of three acceptable options to
express measurements. (1) Use SI units exclusively. (2) Use SI units;
and, if appropriate, provide conventional units parenthetically in the
text and give conversion factors in table footnotes and figure legends.
(3) Use conventional units, if appropriate, and provide SI units
parenthetically in the text and give conversion factors in table
footnotes and figure legends.
Nomenclature.
Chemical and biochemical terms and abbreviations and identification of
enzymes must conform to the recommended usage of the International
Union of Biochemistry and Molecular Biology (IUBMB 1992
). Names for vitamins, related compounds, and abbreviations
for amino acids should follow the ASNS nomenclature policy (AIN 1987b
, AIN 1990
).
Abbreviations.
Use only standard abbreviations (see Huth 1994
and current issues of The Journal). If others are used, define each the first time it is used in the text and prepare an abbreviation footnote. The footnote should be associated with the first abbreviated term in the text and should be an alphabetized listing of all
author-defined abbreviations and their definitions. Units of time
should be abbreviated as: s, min, h, d, wk, and y. Units of length as:
nm, µm, mm, cm, m: units of mass as Da, µg, mg, g, kg.
Radioactivity should be expressed as becquerels (disintegration per
second) or as dpm. Standard abbreviations for SI prefixes and other
units can be found in Young (1987)
. Abbreviations and
unit symbols should not be followed by a period or pluralized.
Acknowledgments.
Technical assistance and advice may be acknowledged in a section at the end of the text.
Literature cited.
The list of references must begin on a new page. Personal
communications and unpublished data cannot be included in the
Literature Cited section but should appear parenthetically in the text.
Personal communications must be written and the affiliation of the
person providing the communication indicated in the text. Articles
accepted for publication but not published when final revisions are
completed on the current article may be cited as "in press."
Abbreviate journal names according to BioSciences Information Service (1994)
. In the text, cite references by author and year
of publication. In the Literature Cited section, cite references
alphabetically, without numbering. Do not use "et al." but include
all authors’ names for every article. See current issues of The
Journal for style.
TABLES, FIGURES, AND AUXILIARY PUBLICATION
Tables and figures.
See current issues of The Journal for style.
Each table (one per page) should have a title that concisely describes the contents. Information concerning methods or explanatory material should be in a footnote to the table rather than in the title. Units of measure should be clearly indicated above the first value in each column or centered over all columns to which the unit applies. Statistics of variability (e.g., SD, pooled SEM) and the significance of differences among the data should be shown.
Tables should be sequentially cited in the text, and the first reference to each table should be in bold face. References cited in tables should be included in the Literature Cited section.
All figures will be reproduced at one-column width (9 cm) unless complexity of the figure demands a two-column width (18.5 cm). Affix a label to the back of each figure with the manuscript title, author’s name, and figure number, and clearly indicate the top. Each copy of the manuscript should have photocopies of figures attached.
Legends for all figures in the manuscript should be compiled and typed double-spaced on a separate page and not on the figures themselves. Titles should be in the legend and not on the figures. Each legend should contain enough detail, including statistics, to ensure that the figure is interpretable without reference to the text.
Tables or figures adapted or reproduced from another source must acknowledge that source in a footnote and be accompanied by written proof that the copyright bearer has granted permission for use of the table.
Auxiliary publication.
Unusually lengthy descriptions of experimental procedures, extensive data, extra figures, etc. may be deposited with the American Society for Information Science, National Auxiliary Publications Service (NAPS). Information on submitting this material can be obtained from the editorial office. A footnote in the publication will give information on the availability of photoprint or microfiche copies at moderate cost.
CHARGES TO AUTHORS
Authors will be billed for the following items: color reproduction costs, author alterations to manuscript proofs, reprints, and page charges at $60 per page. Page charges may be waived by the Society for acceptable reasons such as the lack of funding from grant or institutional sources as verified by an institutional official. Requests for waivers will not affect review of manuscript or delay publication.
A reprint order form with rate list will be sent with author proofs. Reprints are prepared only when ordered by authors and are printed when The Journal is printed. If authors order at least 100 reprints and their supply subsequently becomes exhausted, they may request permission to reproduce a specific limited number of additional reprints.
