The (un)affordability of healthy diets in South Asia and the implications for nutrition-sensitive food policies

The agrifood system in South Asia: Pathways to sustainable healthy diets

South Asia is home to an estimated 2.08 billion people, making it the most densely populated region on the planet. This places immense pressure on the region’s agrifood systems to ensure that healthy and affordable food is available for all, a goal that can only be met by addressing today’s multiple interconnected challenges. Overcoming bottlenecks in agrifood systems — the networks of actors, activities, infrastructure, and policies that are involved in getting food from farms to mouths — requires data and evidence on the many elements of these complex systems. Moreover, that evidence must serve as a catalytic driver of change, which further requires strong partnerships between donors, researchers, civil society, industry, and policymakers. This report begins with a summary of the latest evidence on diets in the region, and then traces the drivers of current diets, starting from the food environment experienced by consumers, back through the diverse markets and farm production, and finally looks at the role of social protection and agrifood policy. The chapters on diets include close looks at consumption of unhealthy foods, the (un)affordability of healthy diets, and behavioral and environmental drivers of food choice. Production-related chapters consider trade-offs between production and consumption as well as how farming households adapt to climate shocks. Other chapters review evidence on the roles of men, women, and adolescents at different points in agrifood systems. The final chapters address lessons learned from social protection and on structural variations in India’s agricultural value chains. Many of the chapters draw from surveys recently conducted in Bangladesh, India, and Nepal under the CGIAR Research Initiative on Transforming Agrifood Systems (TAFSSA).

Nutrition and dietary quality in Sri Lanka: Insights from the 2024-2025 BRIGHT survey

Key findings and policy implications • Dietary quality in Sri Lanka – defined in terms of consumption levels of different healthy food groups – falls well short of the Sri Lankan Ministry of Health’s 2021 Food-Based Dietary Guidelines (FBDG) targets, with clear imbalances across food groups. • Heavy dependence on starchy staples. Starchy foods dense in calories but sparse in nutrients provide over 60% of total energy consumption, highlighting a strong over-consumption of rice. • Low consumption of nutrient-rich foods. Intakes of fruits, dark green leafy vegetables (DGLVs), and legumes are at only about one-third of the recommended levels. • Some households report zero consumption of healthy food groups. More than 30% of households report zero consumption of dairy foods in the past 7 days, while 15% report zero consumption of dark green leafy vegetables, and 5% zero fruit, indicating that important foods are absent from many household diets. • Multidimensional dietary deprivation. Nearly all Sri Lankan households are deprived in at least one food group. A typical deprived household falls below the reference threshold in six to seven of eight food groups and consumes only about 37% of the recommended amounts for the foods in which consumption is lower than recommended. • Significant dietary inequality across sectors. Dietary deprivation is most acute in the estate sector, while rural and urban areas fare moderately better. • There is a clear need to promote healthy dietary diversification, especially higher consumption of fruits, legumes, vegetables and dairy, while moderating excess consumption of starchy staples. • Institutionalize regular monitoring of diet deprivation, using the Reference Diet Deprivation (ReDD) index and other dietary indicators to guide targeted nutrition interventions. • Support further research on the drivers of dietary patterns in Sri Lanka to better understand its determinants and differences between sectors.
