The Claim

In rats with induced diabetes, consumption of wheat chapati stored at room temperature for 24 hours reduced blood glucose levels from 291.0 mg/100mL to 225.2 mg/100mL over a 28-day period.

In plain English

In rats with induced diabetes, eating wheat chapati that had been stored at room temperature for 24 hours lowered blood glucose levels from 291.0 mg/100mL to 225.2 mg/100mL over 28 days.

See the scientific wording

In rats with induced diabetes, consuming wheat chapati stored at room temperature for 24 hours reduced blood glucose levels from 291.0 mg/100mL to 225.2 mg/100mL over 28 days, suggesting a potential glucose-lowering effect of retrograded starch.

Why this might work

When wheat bread is cooked and then cooled, the starch inside changes shape and becomes hard to digest. This undigested starch passes through the small intestine and reaches the colon, where gut bacteria break it down into acids. These acids signal the body to release more insulin and less glucagon, which tells the liver to stop making sugar and store more sugar as glycogen. At the same time, the hard starch slows down how fast sugar enters the blood from the small intestine, keeping blood sugar levels lower.

  1. Study: Effect of cooking and storage temperature on resistant starch in commonly consumed Indian wheat products and its effect upon blood glucose level

    When diabetic rats ate wheat flatbreads that had been left out overnight, their blood sugar went down. The study shows this happened because cooling the bread made a type of starch that digests slowly, helping control blood sugar.
