Nutrient Dense Traditional Foods for Healthier Diets: Linking Indigenous Crops, Food Processing, Packaging, Quality, and Value Chains

The research field of traditional foods and indigenous crops has gained relevance in the context of global nutrition transitions and efforts to build healthier and more sustainable diets. While many indigenous crops and traditional food products are naturally rich in essential nutrients, they remain at the periphery of both academic research and modern food systems integration. Key questions persist regarding how these culturally significant resources can be leveraged to address nutrition deficiencies, support dietary diversity, and enhance food security. Recent studies demonstrate the extraordinary potential of indigenous foods in nutrient composition, climate resilience, and positive community health outcomes, yet persistent barriers, including inadequate processing methods, insufficient packaging, market access limitations, and fragmented value chains, continue to impede their broader impact.Emerging evidence reveals the need for holistic approaches that link crop biodiversity with food science, technology, consumer research, and value chain development. Important work is underway to document nutritional benefits and to optimise processing for nutrient retention, safety, and taste. Advances in sustainable packaging and storage are beginning to address shelf life and food safety concerns for traditional products. However, crucial gaps remain, particularly regarding integrated models that combine indigenous food biodiversity with innovative processing, packaging solutions, and commercial pathways, while upholding food heritage and community benefits. Comprehensive investigation into how value can be added at each stage, the quality and safety can be assured, and equitable commercialisation supported, is still urgently needed to fully realise the public health and socio-economic promise of these foods.This Research Topic aims to foster interdisciplinary research and collaboration that illuminate pathways for mainstreaming nutrient dense traditional foods based on indigenous crops. The goals are to understand and advance how these foods and their associated processing, packaging, and quality assurance methods can be developed, optimised, and scaled within sustainable value chains. The research will seek answers to pressing questions such as how nutrient content and bioavailability can be preserved or enhanced through processing, how packaging innovations can improve shelf life and consumer acceptance, what barriers and enablers affect quality and safety, and how local enterprises and communities can lead and benefit from commercialisation efforts, ensuring the cultural integrity and public health value of traditional food systems are protected. To gather further insights in these areas, we welcome articles addressing, but not limited to, the following themes:o The nutritional, functional, and health-promoting properties of indigenous crops and traditional foodso Innovative food processing and preservation methods that maintain or improve nutrient density and qualityo Packaging designs and materials that augment shelf life, safety, and authenticity for traditional foodso Aspects of food quality, safety, sensory characteristics, and consumer acceptance in diverse settingso Challenges and opportunities in developing sustainable, equitable value chains for traditional and underutilised foodso The roles of women, smallholders, Indigenous communities, and local enterprises in value addition and market expansiono Sustainability dimensions, including environmental impact, postharvest losses, and biodiversity conservationo Policy frameworks, standards, labelling, governance, and community participation to support commercialisation and cultural continuity Topic editors: Fernande Honfo, Dr. Collins Afriyie Appiah Source: https://www.frontiersin.org/research-topics/82288/nutrient-dense-traditional-foods-for-healthier-diets-linking-indigenous-crops-food-processing-packaging-quality-and-value-chains
