The Claim
In healthy Filipino adults, consuming 25 grams of available carbohydrate from black rice produces a glycemic index of 49, which is significantly lower than the glycemic index of 71 produced by consuming 25 grams of available carbohydrate from white rice, and this difference is associated with higher fiber and polyphenol content in black 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.
When healthy Filipino adults eat 25 grams of digestible carbohydrate from black rice, their blood glucose rises less than when they eat the same amount from white rice, due to the higher fiber and polyphenol content in black rice.
See the scientific wording
In healthy Filipino adults, consuming 25 grams of available carbohydrate from black rice results in a significantly lower glycemic index (49) compared to white rice (71), suggesting that unpolished pigmented rice may produce a more favorable acute postprandial glucose response due to higher fiber and polyphenol content.
The outer layers of black rice contain fiber and natural compounds that block digestive enzymes from breaking down starch quickly. This slows the release of sugar into the blood, resulting in a smaller and slower rise in blood glucose after eating.
What the research says
1 studyWhen healthy Filipinos ate black rice instead of white rice, their blood sugar rose much less after eating, likely because black rice has more fiber and natural compounds that slow down how fast sugar enters the blood.
