Diet Beras Merah dan Beras Putih Pratanak Pada Tikus Hiperglikemia

Hyperglycemia is a carbohydrate metabolism disorder causing diabetes. The difference in glycemic index (GI) in red rice and white rice causes different effects on blood glucose. Precooked rice processing causes starch retrogradation which can form Resistant Starch (RS) thereby lowering the GI of rice. Resistant starch is fermented into Short Chain Fatty Acids (SCFAs) and affects the colonic microbiota population. This study aims to determine the effect of precooked red rice and precooked white rice consumption on fasting blood glucose concentration, Ferric Reducing Ability on Plasma (FRAP) concentration, Escherichia coli, and Lactobacillus populations, and SCFAs digesta in hyperglycemic Wistar rats. This study was conducted using 24 male Wistar rats aged 8 weeks with a bodyweight of 200-220 grams. The rats were divided into 4 treatment groups: healthy (S), hyperglycemic (H), a hyperglycemic diet of precooked red rice (H+BMP), and hyperglycemic rats of precooked white rice diet (H+BPP). Consumption of precooked red rice (BMP) for 6 weeks was shown to reduce fasting blood glucose concentration (57.95%), while consumption of cooked white rice (BPP) actually increased fasting blood glucose concentration (4.16%) in hyperglycemic rats. Consumption of BMP also resulted in higher blood antioxidant capacity than BPP. However, consumption of BMP and BPP had no significant effect on the E. coli population, Lactobacillus population, and SCFAs digesta levels.
