The Claim
The optimal cooking process reduces inorganic arsenic in brown rice to 56.1% of original levels and in 10DOP% white rice to 42.0%, indicating that polishing white rice enhances arsenic reduction compared to brown rice under laboratory 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 using an optimal method, white rice with 10% bran remaining has 42.0% of the original inorganic arsenic, while brown rice retains 56.1%, showing that removing more bran reduces arsenic levels more effectively.
See the scientific wording
The optimal cooking process reduces inorganic arsenic in brown rice to 56.1% of original levels and in 10DOP% white rice to 42.0%, suggesting that polishing white rice significantly enhances arsenic reduction compared to brown rice under laboratory conditions.
When the outer layers of rice are removed, more arsenic washes out during cooking because those layers hold most of the arsenic and cooking water can now reach and carry away more of it.
What the research says
1 studyWhen you cook rice the best way, white rice (which has its outer layer removed) loses more arsenic than brown rice, and this study shows that’s true because it looked at how different cooking methods reduce arsenic in both types.
