About this Research Topic

Background

Reactive oxygen species (ROS) and free radicals are a by-product of respiration produced by all aerobic organisms. While they play an essential role in how the cell functions, in excess they can be harmful. Oxidization of some of these biomolecules can result in cell injury. This oxidative damage is linked to the development and progression of many diseases. The mechanism is defined as an imbalance between ROS and antioxidant defense mechanism and termed oxidative stress.

Nutraceuticals are biologically active food, or parts of food, with medical or health benefits, including the prevention and treatment of diseases, especially chronic diseases. Therefore, there is a demand for such preparations; furthermore, they are more readily available than prescription drugs and can be cost-effective.

Currently, our diet is rich in sugars and saturated fats. This diet increases the prevalence of lifestyle complications, including obesity, infertility, and heart diseases. Researchers are trying to establish a relationship between nutraceuticals and their role in improving health. Past studies have indicated that fruits and vegetables decrease the risk of oesophagus, stomach, lung, endometrium, pancreas, oral cavity and colon diseases. Previous studies have established that nutraceuticals can act as free radical scavengers, metal ion chelators or regulators of the intracellular antioxidant defense system, thereby exerting their health-enhancing effects. However, the evidence in many studies are superficial and does not fully encapsulate the potential of nutraceutical in disease prevention.

Therefore, the beneficial role of nutraceuticals and their mechanism on disease activity requires further study. This Research Topic aims to better understand the role of nutraceuticals, especially in the oxidative stress condition of living cells. We also welcome manuscripts that assess the mechanism of action of these nutraceuticals on their target.

We welcome reviews, mini-reviews, and original research articles that provide an in-depth understanding of, but are not limited to, the following subthemes:

1. Nutraceutical supplementation in disease treatment or prevention for in vitro, in vivo, de novo studies.
2. Nutraceuticals usage in preclinical or clinical studies.
3. The mechanism of action underlying antioxidant effects of nutraceuticals.
4. The relationship of oxidative stress or redox status with nutraceuticals in the pathogenesis of the diseases.

All the manuscripts submitted to the collection will need to fully comply with the Four Pillars of Best Practice in Ethnopharmacology (you can freely download the full version here). Specifically, please note:
Pillar 1a) Traditional context - The traditional context must be described in the introduction and supported with bibliographical primary references. This may be based on modern uses of a plant in general healthcare.
Pillar 1b) As you will see in our guidelines and in many other journals' guidelines, chemical anti-oxidant assays like the DPPH assay are of no pharmacological relevance. These are simply chemical tests and there is no evidence for therapeutic benefits on the basis of such chemical assays. Therefore, there can be no 'IC50 values'. Therefore, they can only be included as analytical tools.

Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
