ABSTRACT
Background:
People in Kerala and Tamil Nadu consume Matta rice (MR) and White Ponni rice (WPR) respectively. Less evidence available on the effect of these rice consumption on postprandial blood glucose levels in people with type 2 diabetes (T2DM). Hence, this study aimed to see the effect of post-lunch blood glucose (PLBG) levels after consumption of these rice in people with T2DM.
Methods:
A randomized crossover study was conducted in a tertiary care center for diabetes. A total of 70 Individuals with T2DM who were on oral hypoglycemic agent (OHA) and not on insulin were included. Group 1 (n = 35) received MR for first 2-weeks and WPR for the subsequent 2-weeks. Group 2 (n = 35) received WPR for first 2-weeks and later MR for the subsequent 2-weeks after 1-week washout period. PLBG levels were measured at baseline (BL), 7th and 14th day. Calorie intake using 24 hr-dietary recall was assessed at BL and 14th day. VAS was used to assess satiety and acceptability of the rice.
Results:
Median PLBG levels significantly reduced from MBL (Matta baseline) (195.5 mg/dl) to M7th day (164.5 mg/dl, p = 0.03) and further to M14th (159.5 mg/dl, p = 0.02), WP7th day (160 mg/dl; p = 0.02) and WP14th day (158 mg/dl; p = 0.01), but no difference from MBL to WPBL (196 mg/dl, p>0.05) in group 1. While significant reduction observed from WPBL to M14th day (167 vs. 152 mg/dl; p <0.01) in group 2. Mean difference of PLBG (–31.5 vs. –6.5 mg/dl; p = 0.007) and calorie intake (220 vs. 136 kcal) between MBL-M14th day and WPBL-WP14th day was highly significant. Study participants reported higher satiety (Matta vs. Ponni; 63.8 vs. 6.4%; p < 0.001), and fullness (68.1 vs. 4.3%; p <0.001) after MR consumption while they were very satisfied (Ponni vs. Matta; 66 vs. 23.4%; p <0.001) and stated very tasty (80.9 vs. 21.3%; p < 0.001) with WPR.
Conclusion:
The consumption of Matta rice showed potential reduction on PLBG levels and helped to restrict calorie intake with good satiety and fullness when compared to white rice among participants with T2DM.
