The Claim

Consuming cooled long-grain white rice increases the incidence of postprandial hypoglycemia (≤3.9 mmol/L) by 300% (from 9% to 38%) in adults with type 1 diabetes using insulin pumps with fixed insulin doses, due to reduced digestible carbohydrate content from retrogradation.

Cause and effect

In plain English

Eating cooled long-grain white rice causes a threefold increase in low blood sugar after meals in adults with type 1 diabetes who use insulin pumps with fixed doses, because cooling reduces the amount of digestible carbohydrate.

Why this might work

When rice is cooled after cooking, its starch changes structure and becomes hard to digest. The body cannot break down this changed starch into sugar, so less sugar enters the blood after eating. But the insulin dose stays the same as if the rice were freshly cooked. This causes too much insulin to act on too little sugar, dropping blood sugar to dangerous levels.

  1. Study: Influence of resistant starch resulting from the cooling of rice on postprandial glycemia in type 1 diabetes

    When people with type 1 diabetes eat rice that was chilled overnight and then warmed up again, their blood sugar drops much more than when they eat freshly cooked rice—even if they take the same insulin dose. This study found they were more than three times as likely to get dangerously low blood sugar after eating the cooled rice.
