The Claim
Red rice has a glycemic index of 69, which is statistically similar to the glycemic index of white rice at 71, despite red rice having higher amylose and antioxidant content, and this similarity is attributed to extended cooking times enhancing starch gelatinization and negating the intrinsic glycemic benefits of red rice.
What the research says
Supports is higher
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.
Red rice and white rice have nearly identical glycemic indexes, 69 and 71 respectively, even though red rice contains more amylose and antioxidants; this is because longer cooking times increase starch gelatinization, eliminating any glycemic advantage of red rice.
See the scientific wording
Red rice has a glycemic index of 69, statistically similar to white rice at 71, despite higher amylose and antioxidant content, indicating that extended cooking times may enhance starch gelatinization and negate intrinsic glycemic benefits.
Red rice has more fiber and plant compounds that normally slow sugar release, but when cooked for a long time, the starch becomes fully softened and exposed, allowing digestive enzymes to break it down quickly and release sugar into the blood just like white rice.
What the research says
1 studyRed rice has more fiber and antioxidants than white rice, but when cooked the usual way in the Philippines, it raises blood sugar almost as much as white rice—so those healthy bits don’t help much in practice.
