Nutrition and Healthy Aging is an international forum for research on nutrition as a means of promoting healthy aging. It is particularly concerned with the impact of nutritional interventions on the metabolic and molecular mechanisms which modulate aging and age-associated diseases, including both biological responses on the part of the organism itself and its micro biome. Results emanating from both model organisms and clinical trials will be considered. With regards to the latter, the journal will be rigorous in only accepting for publication well controlled, randomized human intervention trials that conform broadly with the current EFSA and US FDA guidelines for nutritional clinical studies. The journal will publish research articles, short communications, critical reviews and conference summaries, whilst open peer commentaries will be welcomed.

SUBMISSION OF MANUSCRIPT

By submitting my article to this journal, I agree to the IOS Press License to Publish: https://www.iospress.nl/service/authors/author-copyright-agreement/ and the IOS Press Privacy Policy: https://www.iospress.nl/privacy-policy/.

Authors are requested to submit their manuscript electronically to the journal’s editorial management system.
Note that the manuscript should be uploaded as one file with tables and figures included. This file can be a Word document, a PDF, or a zip file.

Peer Review Process and Process for Appeals
Nutrition and Healthy Aging operates a rigorous, timely, blinded peer review process (with an option for double-blind if requested) by experts in the field. Manuscripts submitted to Nutrition and Healthy Aging will be assessed for suitability for publication in the journal by the Editors-in-Chief. Manuscripts that are deemed unsuitable may be rejected without peer review by the Editors-in-Chief and/or the Associate Editors, and the author will be informed as soon as possible. Manuscripts that are deemed suitable for peer review are forwarded to an Associate Editor with expertise in that area who then recruits appropriate anonymous referees (a minimum of two) for confidential review. Referee reports are then assessed by the Associate Editor, who makes a decision which is then subject to approval of the Editors-in-Chief. Once approved this decision is then conveyed to the author along with the referee’s anonymized reports. The initial decision will be one of the following: rejection, acceptance without revision, or potentially acceptable after minor or major revisions. Revised manuscripts will be appraised by the Associate Editor, who may seek the opinion of referees (prior or new) before making a decision, which again is subject to approval of the Editors-in-Chief. Once approved, this decision is then conveyed to the author along with the anonymized referee’s reports. Once accepted, manuscripts are normally published on-line without delay and appear in the next available print issue (published quarterly). The Editors-in-Chief have ultimate responsibility for what is published in the journal. Authors may appeal decisions by contacting the Editors-in-Chief (at editorial@iospress.com). Authors will be informed in writing of the result of their appeal.

Required files
After the article has been accepted, the following electronic files are required:
1. a word processor file of the text, such as Word or LateX (If using LaTeX, please use the standard article.sty as a style file and also send a pdf version of the LaTeX file)
2. separate files of all figures (if any); see "Preparation of manuscripts" for the required file formats.

Submission of an article is understood to imply that the article is original and unpublished and is not being considered for publication elsewhere. Any possible conflict of interest, financial or otherwise, related to the submitted work must be clearly indicated in the manuscript. Procedures involving experiments on human subjects should be in accord with the ethical standards of the Committee on Human Experimentation of the institution in which the experiments were done or in accord with the Helsinki Declaration of 1975. Procedures involving experimentation on animal subjects should be in accord with either the guide of the institution in which the experiments were done, or with the National Research Council’s guide for the care and use of laboratory animals.

If the address to which proofs should be sent is different from the correspondence address, authors are kindly requested to indicate this. Both the editor and the publisher should be informed of any changes in either or both of these addresses. Please also supply a direct telephone number and a fax number, if available.
