About this Research Topic

Background

The global food system has undergone significant transformations due to changes in economic and political status, the built environment, and lifestyle shifts, particularly impacting low- and middle-income countries. These changes have contributed to the emergence of pandemics such as malnutrition, obesity, and food insecurity, which are exacerbated by social and territorial inequalities. Space plays a crucial role in the distribution of goods and services, influencing the quality of human life and the inclusion or exclusion of communities. Current research highlights the need to address the social, structural, and commercial determinants of healthy eating to improve public health outcomes. Despite the recognition of these issues, food insecurity and malnutrition remain prevalent, affecting over a quarter of the global population and contributing to the rise in obesity rates. The agro-industrial food system, characterized by the high availability of ultra-processed foods, perpetuates these challenges by influencing dietary choices and exacerbating poverty and inequality. There is a pressing need for studies that consider local contextual characteristics to develop effective public policies that address these determinants and promote healthy eating.

This research topic aims to explore the complex interplay between food insecurity, malnutrition, and the food environment in low- and middle-income countries. The objective is to provide a comprehensive overview of the latest findings, analyze existing data, and offer new perspectives on the challenges and opportunities within this field. By examining the local social, commercial, territorial, and structural determinants of healthy eating, the research seeks to identify effective policy interventions and measures that can strengthen food systems and environments, ultimately improving public health outcomes.

To gather further insights in the context of low- and middle-income countries, we welcome articles addressing, but not limited to, the following themes:
- Assessment of food insecurity in different populations
- Unhealthy food environments that promote malnutrition and/or food insecurity
- Evaluation of the food environment across various dimensions
- Strengthening food systems and environments to protect public health
- Nutritional status and the relationship between food insecurity and the food environment
- Food choices and their association with the food environment
- Policy interventions and measures around this topic
- Spatial analyses regarding the distribution of goods and services, particularly in LMICs.

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.
