Health and Nutrition as Drivers of Sustainable Economic Development: A Study on Millennials in Tiruchirappalli

Abstract

Health and nutrition play a fundamental role in shaping the productivity, employability and long-term economic well-being of individuals, thereby acting as key drivers of sustainable economic development. This study explores the intricate linkages between dietary habits, health outcomes and economic participation among the millennial population (aged 25–40) in Tiruchirappalli. The research is grounded in the understanding that millennials, being the largest working-age group, represent both the present and future contributors to economic growth. Adopting a mixed-method approach, the study employs structured questionnaires and focus group discussions to capture insights on nutritional practices, health awareness, lifestyle patterns and their perceived impact on income, job performance and savings. Preliminary findings suggest that inadequate nutrition and lifestyle-related health challenges such as obesity, stress and chronic illness adversely affect productivity, while balanced dietary practices and preventive healthcare significantly enhance economic resilience. The paper further examines how local socio-economic factors, urbanization and cultural food practices influence millennials’ health behaviours in Tiruchirappalli. The study also identifies key challenges such as rising fast-food consumption, sedentary lifestyles and limited awareness of nutrition literacy. Policy implications are discussed in relation to promoting affordable nutrition, workplace wellness initiatives and community-level interventions that can strengthen human capital. By situating the analysis within the broader discourse on sustainable development, this study underscores that investing in health and nutrition is not merely a social responsibility but a strategic economic imperative.
