The Claim

Rice varieties with higher resistant starch content do not consistently exhibit slower starch digestion rates, as evidenced by Youtangdao 3, which contains 8.15 times more resistant starch than Guangluai 4 but demonstrates faster digestion due to lower cohesiveness.

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

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

In plain English

Rice with more resistant starch does not always digest more slowly; one variety with over eight times more resistant starch digests faster than another due to differences in physical structure.

See the scientific wording

Higher resistant starch content in rice does not consistently correlate with slower starch digestion, as demonstrated by Youtangdao 3, which has 8.15 times more resistant starch than Guangluai 4 but digests faster due to lower cohesiveness.

Why this might work

When rice is cooked, the starch forms a gel. If the gel is less sticky, digestive enzymes can reach the starch more easily and break it down faster, even if there is a lot of starch that normally resists digestion. The structure of the gel determines how fast digestion happens, not just how much resistant starch is present.

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

    Even though this type of rice has way more resistant starch, it breaks down faster because it’s less sticky, letting digestive enzymes get to the starch more easily. So more resistant starch doesn’t always mean slower digestion.
