Aim & Scope
The International Journal of Nutrology (IJN) is the official scientific journal of the Brazilian Association of Nutrology (ABRAN). Established in 2011, IJN is a quarterly, open-access, peer-reviewed journal focused on clinical nutrology, nutrition-related medical care, nutritional assessment, metabolism, and evidence-based dietary approaches to disease prevention and treatment.
Nutrological Science encompasses the scientific investigation of nutrients, foods, dietary patterns, metabolism, nutritional status, body composition, biological mechanisms, and their relationships with health and disease. Nutrological Health encompasses the assessment, prevention, diagnosis, treatment, monitoring, and rehabilitation of nutrition-related conditions and the promotion of human health through evidence-based nutrological and dietary care.
Centered on Nutrological Science and Nutrological Health, IJN welcomes multidisciplinary research from Agricultural and Biological Sciences, including Food Science and agronomy; Medicine, including Medicine (miscellaneous) and all medical specialties; Nursing; Nutrition and Dietetics; Dentistry; and related health, biomedical, and life-science fields, provided that the manuscript makes a direct, explicit, and substantial contribution to nutrology, nutrition, metabolism, dietary care, or nutrition-related human health.
IJN publishes clinical, epidemiological, translational, preclinical, and experimental research when the manuscript addresses a clearly defined nutrological, nutritional, metabolic, or diet-related question. Studies from medicine, nursing, dentistry, sports, food science, microbiology, pharmacology, genetics, public health, or omics are considered when nutrition, dietary exposure, metabolism, body composition, Nutrological Science, or Nutrological Health is a central element of the objectives, methods, results, and conclusions.
General health, agricultural, industrial, laboratory, educational, or product-development studies without a direct nutritional or human health outcome are outside the journal's scope.
Publication Formats
IJN publishes original articles, review articles, case reports, and letters to the editor. Journal content may be organized in regular issues, supplements, and special issues, each clearly identified in the issue title and publication metadata.

Preprints
Posting a manuscript on a recognized preprint server does not by itself constitute prior publication. Authors must disclose any preprint at submission and provide its DOI or persistent link. If the article is published by IJN, the authors should update the preprint record with a link to the Version of Record. The preprint policy does not permit simultaneous submission to more than one journal.

IJN's mission is to serve the scientific and clinical communities by publishing rigorous, relevant, and ethically conducted research that advances Nutrological Science, Nutrological Health, evidence-based nutritional care, and their contribution to human health.
Recognition of Editors and Reviewers
IJN recognizes the essential contributions of editors and peer reviewers to the quality and integrity of the journal. Reviewers may receive documentation of their completed review activity, subject to the journal's confidentiality requirements. Review activity may be recorded through compatible third-party recognition services only when confidentiality is preserved and no manuscript, author, reviewer, or editorial information is improperly disclosed.
