Special Issue Information
Dear Colleagues,
In recent years, the concept of “healthy longevity” has received widespread attention due to its focus on both increasing an individual’s overall life expectancy or longevity, on extending life without serious chronic diseases, and on “health span”. The U.S. National Academy of Medicine defines health span as “good health, close to biological lifespan, with physical, cognitive, and social functioning, and the ability to achieve well-being”.
Various components of the diet play a crucial role in regulating the aging process and longevity, as well as the development of age-related diseases. Dietary interventions and functional foods help to promote healthy aging and longevity. In addition, the risk of malnutrition among older adults has emerged as a significant concern, contributing to an enhanced risk of chronic diseases and affecting their overall well-being. Innovative foods that are designed to specifically target the nutritional deficiencies prevalent among older adults—such as insufficient protein, fiber or antioxidants—can play a critical role in enhancing their overall health status.
On the other hand, biomarkers of aging are important tools that enable these objectives to be achieved over realistic time frames. However, the current lack of standards and consensus regarding the properties of a reliable aging biomarker hinders their further development and validation for clinical applications.
The effects of chronic diseases and multimorbidities include disability, a reduced quality of life, frailty, a shorter life expectancy, and a greater need for healthcare resources. On the other hand, sarcopenia, which is characterized by the age-related loss of skeletal muscle mass and strength, is a natural consequence of aging. While it is a normal part of aging, the rate of muscle loss can be influenced by factors such as physical activity, nutrition, and other health conditions. Identifying risk factors that adversely affect the quality of life of older individuals is a critical public health concern.
This Special Issue aims to enhance our understanding of the role of nutritional biomarkers in healthy aging. The scope of this Special Issue includes, but is not limited to, the following topics:
- The effects of macro and micronutrients on the metabolism and biological markers of aging adults.
- Associations between nutritional biomarkers and biological aging.
- The mechanisms by which functional nutrients may prevent age-related diseases.
- The identification of novel aging biomarkers from omics technologies and their association with nutrition.
- The impact of dietary interventions on healthy longevity.
- New fortified food designs that specifically target healthy aging.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
