Functional Nutraceutical in the Prevention and Management of Lifestyle-Associated Metabolic Disorders — A Comprehensive Review

Odisha, a state in eastern India, is renowned for its rich agricultural biodiversity, especially indigenous rice landraces that possess high nutritional and nutraceutical potential.

This review synthesises literature on these rice varieties, their nutritional attributes, mechanisms relevant to metabolic health, and implications for dietary and public health interventions.
