Assessment of the nutritional value of selected wild food plants in Türkiye and their promotion for improved nutrition

Türkiye represents one of the world’s biodiversity hotspots, containing over 11,000 species of plants, with an estimated 10% being edible. Wild food plants, especially in rural areas, are collected and eaten or sold in local markets, complementing people’s diets, and represent a source of additional income for foraging households. Yet, the use of wild food plants is declining, with both their dietary and cultural values being undermined. Wild food plants can be used as a healthy dietary alternative to imported and ultra-processed foods, particularly as the Turkish population increasingly suffers from diet-related diseases. Using a unique and innovative approach to mainstream biodiversity for food and nutrition, wild food plants from five different regions of Türkiye were analyzed to determine their nutrient composition, and to evaluate their contribution not only to diets and nutrition, but to promoting a more sustainable food system. Examples are presented of how the approach was put into practice and how action was taken to (i) strengthen the evidence of the nutritional value of wild food plants; (ii) use this knowledge to shape new policies and identify emerging markets for food biodiversity; and, (iii) improve awareness of consumers, using capacity building and farmer training, gastronomy, and cultural events

The potential of neglected and underutilized species for improving diets and nutrition

The paper highlights the novel and ingenious approaches Brazil, Kenya, Sri Lanka and Turkey used to prioritize a rich diversity of NUS for healthier diets and improved nutrition, and how this knowledge was used to mainstream these plant species into production and consumption systems. The paper concludes with some perspectives on the way forward for NUS and the community working on them in meeting the challenges of malnutrition and environmental sustainability in the 2030 sustainable development context
