The Claim

The glycemic response to meals containing lentils varies by formulation, with lentil side dishes producing a lower relative glycemic response (30 ± 4%) compared to lentil meatloaf and vegetarian meatloaf, indicating that non-lentil ingredients in the formulation influence postprandial glucose levels.

In plain English

Meals made with lentils as a side dish cause a lower rise in blood sugar than lentil meatloaf or vegetarian meatloaf, and this difference is due to the other ingredients in the dish.

See the scientific wording

The glycemic impact of lentil-containing meals varies significantly based on formulation, with lentil side dish showing the lowest relative glycemic response (RGR) of 30 ± 4%, while lentil meatloaf and vegetarian meatloaf showed higher RGR values, indicating that ingredient composition beyond lentils influences postprandial glucose.

Why this might work

When lentils are eaten in whole or minimally processed forms, their natural cell walls and fiber trap starch inside, making it hard for digestive enzymes to break it down. This slows the release of glucose into the gut, so blood sugar rises slowly and stays low. When lentils are ground into fine flour or cooked in ways that break open their cells, the starch becomes easy for enzymes to reach, causing a fast spike in blood sugar.

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

    The study found that how lentils are cooked or processed changes how much they raise blood sugar—boiled lentils cause a small spike, but powdered lentils cause a bigger spike. So yes, what else is in the meal and how the lentils are prepared really matters.
