From Leftovers to Lifelines: Unava Marunthu and the Cultural Ecology of Fermented Rice in Rural Tamil Nadu

Abstract

Fermented rice is a traditional cereal-based food widely consumed across South and Southeast Asia, valued for its simplicity, digestibility, and cultural significance. In Tamil Nadu, fermented rice locally known as pazhaya sadham is closely associated with the indigenous food philosophy of unava marunthu, which views food as both nourishment and medicine. Rooted in everyday rural life, this practice reflects an intimate relationship between diet, climate, labour, and sustainability.
The present study documents household-level preparation methods, consumption practices, and commonly used accompaniments of fermented rice in the Chunampet area of Tamil Nadu. The study focuses on how inherited culinary knowledge is practiced in contemporary rural settings through routine food habits. Fermented rice continues to be prepared using simple household methods and consumed primarily as an early-day meal, reflecting its role as a cooling, filling, and easily digestible food.
The study underscores the relevance of fermented rice as an expression of unava marunthu, where leftover utilization, bodily well-being, and cultural continuity converge. Documenting such indigenous food practices contributes to the preservation of traditional knowledge systems and highlights their role in promoting sustainable and health-supportive diets.
