India’s Changing Diet: Millets, Processed Foods, and the Nutrition Crisis

Background: India’s dietary landscape has shifted markedly over the past decade, marked by a decline in traditional staples and a rapid rise in ultra-processed food (UPF) consumption. While policy-driven efforts have attempted to revive millets for their nutritional and ecological benefits, these initiatives face stiff competition from the growing demand for convenience-based, energy-dense foods. Methods: This study employed a mixed-methods approach, drawing on nationally representative datasets (NSSO, CNNS, NFHS, IFPRI) and qualitative literature from academic, policy, and limited media sources. Quantitative analysis tracked trends in cereal and UPF consumption, nutrition indicators (stunting, overweight), and household food expenditure (2011–2025). Thematic coding of qualitative data explored consumer behavior, policy interventions, and regional disparities. Results: Between 2015 and 2023, household spending on UPFs nearly doubled from 6.5% to 12%, while per capita millet consumption rose modestly from 2.1 kg/year to 3.3 kg/year. Despite these gains, child stunting remains high at 35.5%, and adult overweight rates have nearly doubled, particularly in urban areas. Only 28% of adults meet dietary diversity guidelines, and added sugar intake among children far exceeds WHO recommendations. Discussion: Urbanization, income growth, and changing lifestyles are accelerating India’s nutrition transition. While millet promotion policies show some promise, especially in states with supportive procurement and public distribution systems, barriers such as price, taste, and culinary unfamiliarity hinder broader adoption. In contrast, UPFs benefit from aggressive marketing and accessibility. The resulting double burden of malnutrition underscores the need for coordinated, multisectoral interventions. Conclusion: India’s food system is at a crossroads. Combating the dual challenge of undernutrition and diet-related non-communicable diseases demands robust regulatory action (e.g., sugar taxes), increased investment in nutrition education, and expanded support for traditional, climate-resilient crops like millets.
