The Claim

Boiled or pureed green lentils significantly reduce postprandial blood glucose response compared to potato-based meals in healthy adults, with relative glycemic responses averaging 40% versus 73% for potato.

Cause and effect

In plain English

When healthy adults eat boiled or pureed green lentils instead of potato-based meals, their blood glucose levels after eating are lower, averaging 40% compared to 73% with potatoes.

See the scientific wording

Boiled or pureed green lentils significantly reduce postprandial blood glucose response compared to potato-based meals in healthy adults, with relative glycemic responses averaging 40% versus 73% for potato, indicating that lentil-based foods can attenuate acute blood sugar spikes when substituted for high-glycemic ingredients.

Why this might work

When lentils are boiled or pureed, their natural cell walls stay mostly intact, forming a physical barrier that blocks digestive enzymes from breaking down starch quickly. The high fiber and protein in lentils also make the contents of the intestine thicker and slower to move, which delays how fast glucose enters the bloodstream. This results in a much smaller and slower rise in blood sugar compared to potatoes, which have no such barriers and release glucose rapidly.

  1. Study: Effect of Processing on Postprandial Glycemic Response and Consumer Acceptability of Lentil-Containing Food Items

    When people ate meals made from boiled or blended lentils, their blood sugar rose much less than when they ate meals with instant potatoes. The study proved lentils help keep blood sugar more stable after eating.
