The Claim
Cold storage of cooked rice reduces pore size in the rice matrix and increases the number of nanoscale pores, which correlates with reduced enzymatic hydrolysis of amorphous starch regions and higher levels of slowly digestible starch.
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.
Chilling cooked rice changes its internal structure to create more tiny pores, which is associated with slower breakdown of starch during digestion and higher levels of slowly digestible starch.
See the scientific wording
Cold storage of cooked rice reduces pore size in the rice matrix and increases the number of nanoscale pores, which correlates with reduced enzymatic hydrolysis of amorphous starch regions and higher levels of slowly digestible starch.
When cooked rice cools down, the starch molecules rearrange into tighter, more ordered structures, creating more tiny pores but making them smaller and harder for digestive enzymes to enter. This blocks the enzymes from breaking down the starch quickly, so the starch digests slowly and turns into slowly digestible starch instead of being absorbed as sugar right away.
What the research says
1 studyCooling cooked rice changes its tiny internal structure, making it harder for digestive enzymes to break down the starch, which means your body absorbs the sugar from it more slowly. The study found this actually happens — cooled rice has more tiny pores and slower-digesting starch.
