Metabolic & Cardiometabolic
Does coarse chickpea flour lower blood sugar after a meal?
The claim, precisely: cellular chickpea flour decreases postprandial glucose
Strong support Metabolic & Cardiometabolic
RefutedContestedStrong support
consensus score 1.00
Yes, when coarsely milled so starch stays locked in cells; grinding it fine erases the benefit.

What the evidence shows
Coarse, cellular chickpea flour attenuates postprandial glucose; fine milling erases the benefit (cell-wall encapsulation of starch is the active mechanism).
