The Claim
Cooling long-grain white rice for 24 hours at 4°C and reheating it before consumption reduces the maximum postprandial blood glucose increase by 31% (from 3.9 to 2.7 mmol/L) and decreases the area under the glycemic curve by 60% (from 336 to 135 mmol/L·180 min) in adults with type 1 diabetes using insulin pumps with fixed bolus doses, due to increased resistant starch content from retrogradation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Cooling long-grain white rice for 24 hours at 4°C and reheating it before eating lowers the peak rise in blood glucose by 31% and reduces the total blood glucose exposure over 180 minutes by 60% in adults with type 1 diabetes who use insulin pumps with fixed doses, because the cooling process increases resistant starch.

When rice is cooled after cooking, its starch molecules rearrange into a tight, crystalline structure that the body cannot break down. This means less sugar is released from the rice during digestion, so less glucose enters the bloodstream after eating.
What the research says
1 studyChilling rice overnight and reheating it makes some of its starch harder to digest, so less sugar enters the blood after eating. This study proved it cuts blood sugar spikes by about one-third and total sugar exposure by 60% in people with type 1 diabetes who don’t change their insulin.
