American Journal of Clinical Nutrition

American Journal of Clinical Nutrition is a prominent monthly peer-reviewed medical journal covering all aspects of human nutrition. It is published by the American Society for Nutrition and serves as a leading forum for the publication of primary research and critical reviews in the field. The journal is widely recognized for its rigorous scientific standards and its influence on public health policy and clinical practice guidelines globally.

History and background

The journal was established in 1952, originating from the proceedings of the annual meetings of the American Institute of Nutrition, which later became the American Society for Nutrition. Its founding was part of a broader post-war scientific expansion, coinciding with increased research into vitamin metabolism and protein requirements. Over the decades, it evolved from a society proceedings publication into a premier independent research journal, reflecting the growing sophistication of nutritional science and its intersections with fields like endocrinology and epidemiology. Key figures in its development have included editors from major institutions such as the Harvard T.H. Chan School of Public Health and the United States Department of Agriculture.

Scope and editorial focus

The journal's scope encompasses original research on human nutritional physiology, dietary assessment, nutrient requirements, and the role of diet in the prevention and management of chronic disease. It places a strong emphasis on studies involving human subjects, including randomized controlled trials, cohort studies, and meta-analyses. Core areas of focus include obesity, cardiovascular disease, type 2 diabetes, micronutrient deficiencies, and lifecycle nutrition from pregnancy to old age. The journal also publishes scholarly reviews and editorials that address contemporary controversies and synthesize evidence for translation into practice.

Abstracting, indexing, and impact

The journal is abstracted and indexed in major scientific databases including PubMed, MEDLINE, Science Citation Index Expanded, and Scopus. According to the Journal Citation Reports, it consistently holds a high impact factor, ranking it among the top journals in the categories of Nutrition & Dietetics and Endocrinology & Metabolism. Its high citation metrics underscore its authority and the widespread influence of its published research on subsequent scientific inquiry, National Institutes of Health funding priorities, and international bodies like the World Health Organization.

Notable articles and research

The journal has published numerous landmark studies that have shaped nutritional science and public policy. Seminal work includes pivotal research on the Mediterranean diet and cardiovascular health, influential trials on folic acid supplementation and neural tube defects, and definitive studies on dietary fiber and colorectal cancer risk. It has also featured critical papers debunking popular diet myths and clarifying the roles of saturated fat and dietary cholesterol in disease etiology, often involving large cohorts like the Nurses' Health Study or collaborations with the Framingham Heart Study.

Editorial policies and peer review

The journal employs a rigorous single-blind peer review process overseen by an international editorial board comprising experts from institutions like the University of Cambridge and the Johns Hopkins Bloomberg School of Public Health. It adheres to the International Committee of Medical Journal Editors recommendations for publication ethics. All clinical trials must be registered in repositories such as ClinicalTrials.gov, and the journal mandates strict conflict of interest disclosures. It supports initiatives for data sharing and open science, offering various publication tracks including traditional subscription and open access options.

Related publications

The American Society for Nutrition also publishes several other journals that complement its scope. These include the Journal of Nutrition, which focuses more on basic nutritional biochemistry and animal studies, and Advances in Nutrition, which publishes comprehensive review articles. Other notable related publications in the broader field include the British Journal of Nutrition, the European Journal of Clinical Nutrition, and the Annual Review of Nutrition, each contributing to the diverse ecosystem of scholarly communication in nutritional science.
