The Claim

The japonica rice variety Youtangdao 3 has a 36% shorter active digestion duration and a 24% faster glucose production rate than the indica rice variety Guangluai 4, despite comparable amylose content, due to reduced cohesiveness in the cooked grain that enhances enzyme accessibility to starch.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When cooked, the rice variety Youtangdao 3 breaks down starch into glucose faster and for a shorter time than Guangluai 4, even though both have the same amount of amylose, because its cooked grains are less sticky and allow digestive enzymes to reach the starch more easily.

See the scientific wording

Among high-amylose rice varieties, the japonica variety Youtangdao 3 exhibits a 36% shorter active digestion duration and a 24% faster glucose production rate than the indica variety Guangluai 4, despite having similar amylose content, due to lower cohesiveness in the cooked grain, which increases enzyme accessibility to starch.

Why this might work

When the rice grain is cooked, less stickiness allows digestive enzymes to reach the starch more easily, breaking it down faster and releasing glucose more quickly, even though some starch resists digestion.

1 study
  1. Study: Contrasting starch digestion and physiochemical characteristics between japonica and indica rice varieties with comparable high-amylose content

    Even though both rices have the same amount of amylose, the japonica rice (Youtangdao 3) is less sticky when cooked, so digestive enzymes can break it down faster and release glucose more quickly than the indica rice (Guangluai 4).
