The Claim

In healthy adults with elevated fasting glucose, consuming 10 grams of 1-kestose with a 75-gram carbohydrate rice meal reduces postprandial glucose incremental area under the curve by approximately 18% and insulin incremental area under the curve by approximately 16%, without increasing GLP-1 levels.

In plain English

When healthy adults with high fasting blood sugar eat a rice meal with 10 grams of 1-kestose, their blood glucose and insulin levels rise less after eating compared to eating the meal without 1-kestose, and this effect does not involve increased GLP-1 hormone levels.

See the scientific wording

In healthy adults with elevated fasting glucose, consuming 10 grams of 1-kestose with a 75-gram carbohydrate rice meal significantly reduces postprandial glucose and insulin incremental area under the curve by approximately 18% and 16%, respectively, without increasing GLP-1, suggesting a mechanism distinct from incretin stimulation.

Why this might work

When 1-kestose is eaten with a starchy meal, it slows down how fast food moves through the intestine. This causes glucose from the meal to be absorbed more slowly, so blood sugar and insulin do not spike as high.

    When people with slightly high blood sugar ate rice with 10 grams of 1-kestose, their blood sugar and insulin didn’t spike as much as usual — just like the claim says. And it wasn’t because of a fullness hormone called GLP-1, since that didn’t go up.
