The Claim
Boiling, soaking, or washing rice with arsenic-contaminated water does not reduce arsenic levels in rice and may result in no change or increased arsenic content under these conditions.
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.
Boiling, soaking, or washing rice with water that contains arsenic does not lower the amount of arsenic in the rice and might leave it unchanged or even increase it.
See the scientific wording
There is no evidence from this study that boiling, soaking, or washing rice reduces arsenic levels when performed with arsenic-contaminated water, and the methods may be ineffective or counterproductive under these conditions.
When rice is boiled, soaked, or washed in water containing arsenic, the arsenic dissolves into the water and gets absorbed into the rice grains through their outer layers. The rice does not expel arsenic during these processes, and the amount of arsenic that enters the grain exceeds any that might be washed away, leading to higher arsenic levels in the cooked rice.
What the research says
1 studyIf you wash or boil rice with water that has arsenic in it, the rice can end up with more arsenic than before — so these methods don’t help and might even make it worse.
