The Claim

Consumption of Koshinokaori rice results in a significantly lower glycemic response compared to standard rice at 60, 90, and 120 minutes post-consumption in healthy Japanese adults, with a delayed and blunted postprandial glucose peak.

In plain English

Koshinokaori rice causes a smaller and slower rise in blood sugar after eating compared to regular rice in healthy Japanese adults.

See the scientific wording

The glycemic response to Koshinokaori rice is significantly lower than standard rice at 60, 90, and 120 minutes after consumption in healthy Japanese adults, indicating a delayed and blunted postprandial glucose peak.

Why this might work

The rice has a special type of starch that stays tightly packed even after cooking, so digestive enzymes cannot break it down quickly. This means glucose is released slowly into the gut, leading to a gradual rise in blood sugar instead of a sharp spike.
