The Claim

The chain length distribution of amylopectin, specifically chains with a degree of polymerization between 13 and 36, is strongly associated with the rate and extent of rapidly digestible starch hydrolysis in cooked white rice.

Source: Fine structure of starch biomacromolecules and digestibility: The regulative role of amylose and amylopectin in the digestive hydrolysis of starch in rice.

In plain English

In cooked white rice, the specific length of starch chains between 13 and 36 glucose units is linked to how quickly and completely the starch breaks down during digestion.

See the scientific wording

The chain length distribution of amylopectin, particularly chains with a degree of polymerization between 13 and 36, is strongly associated with the rate and extent of rapidly digestible starch hydrolysis in cooked white rice.

Why this might work

In cooked rice, starch molecules with short and medium-length branches (13 to 36 sugar units) are broken down quickly because digestive enzymes can easily attach to many ends of these chains, releasing glucose fast. Longer or shorter branches are harder for enzymes to attack, so they break down slowly.

    The study found that the parts of rice starch made of 13 to 36 sugar units break down fastest in your gut — exactly what the claim says. Longer or shorter chains don’t get digested as quickly.
