Healthy Diets from Sustainable Sources

This topic delves into the evidence-based definition and components of a healthy diet that is sourced from environmentally sustainable food systems, as outlined by global initiatives like the EAT-Lancet Commission. For Zambian tertiary students in nutrition, dietetics, and food science, it involves studying dietary patterns—such as flexitarian, pescatarian, and plant-based diets—that optimize human health while respecting planetary boundaries. The curriculum covers national food-based dietary guidelines, nutrient bioavailability, and the trade-offs between nutritional adequacy, environmental impact (land use, water, emissions), and economic accessibility. Students will critically analyze the affordability and feasibility of recommended diets in low and middle-income contexts like Zambia. This knowledge is vital for future nutritionists and public health professionals aiming to design culturally appropriate, sustainable, and effective dietary interventions to combat both undernutrition and diet-related non-communicable diseases in Zambian communities.
