The Claim
In vitro enzymatic digestion of cold-stored and microwave-reheated cooked rice produces a resistant starch content of approximately 30.06%, which is higher than the resistant starch content observed in freshly cooked rice under identical in vitro conditions.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When cooked rice is cooled and then reheated in a microwave, laboratory tests show it contains about 30.06% resistant starch, which is more than freshly cooked rice tested the same way.
See the scientific wording
In vitro enzymatic digestion of cold-stored and microwave-reheated cooked rice results in resistant starch content of approximately 30.06%, which is higher than that of freshly cooked rice, but this finding is limited to laboratory conditions and does not reflect human digestion or metabolic outcomes.
When cooked rice is cooled, its starch molecules rearrange into tight, crystalline structures. Microwaving the cooled rice partially breaks apart some of these structures but leaves behind other dense, ordered forms that block digestive enzymes from breaking down the starch. This makes more starch pass through the digestive system unchanged.
What the research says
1 studyIn a test tube, cooled and microwaved rice has about 30% more starch that doesn’t get broken down than fresh rice — and the study confirms this, while also saying it doesn’t mean it’s better for your body.
