The Claim
Increasing the water-to-rice ratio from 1.5:1 to 6:1 during soaking reduces total arsenic content in rice by 4.4% to 7.5% depending on soaking duration, due to dilution and leaching mechanisms 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.
Soaking rice in six times its volume of water instead of 1.5 times reduces arsenic levels by 4.4% to 7.5%, with the amount of reduction depending on how long the rice is soaked.
See the scientific wording
Increasing the water-to-rice ratio from 1.5:1 to 6:1 during soaking reduces total arsenic by 4.4% to 7.5% depending on soaking duration, demonstrating that dilution and leaching during soaking can modestly lower arsenic content in rice under laboratory conditions.
When rice is soaked in a large amount of water, arsenic dissolved inside the grain moves out into the water because the water has much less arsenic than the grain. The more water used and the longer the soaking, the more arsenic leaves the grain.
What the research says
1 studyThis study found that soaking rice in more water helps wash out some of the harmful arsenic, just like the claim says. More water = a little less arsenic, especially if you soak it longer.
