High-resistant starch rice lowers blood glucose in diabetes
Last updated August 23, 2026
Key finding
The increments of the postprandial blood glucose levels for high-RS rice were significantly lower than that for ordinary rice, i.e., 2.80 ± 1.38 mmol/L vs. 3.04 ± 1.50 mmol/L (P = 0.043)
A study evaluated the effects of high-resistant starch rice on postprandial glycemia in type 2 diabetes patients, finding it significantly reduced blood glucose levels compared to ordinary rice.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
A study evaluated the effects of high-resistant starch rice on postprandial glycemia in type 2 diabetes patients, finding it significantly reduced blood glucose levels compared to ordinary rice.
Clinical relevance
These findings are clinically significant as they suggest that incorporating high-resistant starch rice into the diet of patients with type 2 diabetes may help in better managing postprandial blood glucose levels. This could lead to improved overall glycemic control, potentially reducing the risk of diabetes-related complications and enhancing quality of life for patients.
Keep in mind
Limited to a specific population of type 2 diabetes patients. Results may not be generalizable to other populations or dietary contexts. Potential confounding factors not fully controlled.

Main Effects
High-resistant starch rice reduced postprandial blood glucose increment at 30 min by 0.24 mmol/L (P = 0.043).
High-resistant starch rice reduced postprandial blood glucose increment at 60 min by 0.31 mmol/L (P = 0.036).
High-resistant starch rice decreased the incremental area under the blood glucose curve at 120 min by 25.17 mmol/(L·min) (P = 0.042).
