Revealing The Nutritional, Antioxidant and Antidiabetic Potentials of Kattuyanam- An Indigenous Rice Variety Of Tamil Nadu
Abstract
Diabetes is a chronic metabolic disorder which occurs when the body fails to utilize glucose properly. Even though a number of factors are associated with the cause of diabetes, higher consumption of polished white rice is related with an increased risk of it in recent years. On the other hand, the pigmented rice varieties are getting research of interest since are enriched with a number of phytoconstituents and antioxidants. Kattuyanam, one such pigmented rice variety of Tamil Nadu is very well known for its antidiabetic property and low glycemic index. But scientific knowledge about the rice variety is not reported till date. The present study was aimed at revealing the nutritional property of Kattuyanam rice along with its antidiabetic efficiency. To our best knowledge, the present work is the first description on the nutritional and antidiabetic potential of Kattuyanam rice. The nutritional profiling of the Kattuyanam rice showed that it contained lowered sugar levels and fat content, increased dietary fiber and protein content. The scavenging assay of the extracts of Kattuyanam rice exhibited good antioxidant properties with significantly higher inhibition rate. Since the antidiabetic property residing in the Kattuyanam rice is not yet revealed scientifically, this study aims in evaluating the same through in vitro methods. The glucose diffusion inhibition, significant glucose adsorption capacity and enhanced uptake of glucose by the extracts of Kattuyanam rice proved its antidiabetic properties. The results of the present study will pave a way for developing a diet strategy for managing Diabetes mellitus.
