The Study
Effects of Consuming Heat-Treated Dodamssal Brown Rice Containing Resistant Starch on Glucose Metabolism in Humans
This study is like a fair test where two groups of people ate different kinds of rice, and one group had a special kind that doesn't digest easily. After two weeks, the group with the special rice had slightly better blood sugar numbers. But it's not proof it will fix diabetes — it just shows a small hint that it might help.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
This study tested a special kind of brown rice that has a type of starch your body can't digest, called resistant starch.

Key takeaways
Summary
Based on the study abstract and findings.
- 1These changes suggest the rice helps your body use insulin better and reduces sugar damage, even if you don't lose weight.
- 2People who ate 19.6 grams of this rice daily for 2 weeks saw their insulin resistance drop by 1.5%, their skin AGEs (harmful sugar compounds) drop by 0.06%, and their fasting insulin drop by 5.71 uU/dL — but their weight didn't change.

Some types of starch pass through the small intestine without being broken down, so no glucose is absorbed from them.
Obese adults who ate 19.6 grams of resistant starch from Dodamssal rice daily for two weeks had a measurable drop in fasting insulin levels, while those who did not consume it showed no change.
Eating 19.6 grams of resistant starch daily from heat-treated Dodamssal brown rice for two weeks reduces insulin resistance by 1.5% in obese adults, as measured by HOMA-IR, without requiring weight loss.
Eating 19.6 grams of resistant starch from heat-treated Dodamssal brown rice daily for two weeks lowers skin autofluorescence by 0.06% in obese adults, indicating reduced levels of advanced glycation end-products.
Consuming 19.6 grams of resistant starch from Dodamssal rice for two weeks does not change body weight, waist size, or body fat percentage in obese adults.
Heat-treated Dodamssal brown rice has 11.4% resistant starch and a glycemic index of 56, compared to 70.5 for regular rice, and causes a lower rise in blood glucose after eating.
