The Claim
Cooking traditional rice with a 1:6 water-to-rice ratio after five washes reduces inorganic arsenic content by 20–39%, while rice cooker methods using a 1:2 water-to-rice ratio reduce inorganic arsenic by 1–17%, demonstrating that higher water volume and discarding cooking water are key factors in reducing inorganic arsenic in 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.
Cooking rice with six times its volume in water and discarding the water after five washes removes 20–39% of inorganic arsenic, while using a rice cooker with twice its volume in water removes only 1–17%.
See the scientific wording
Traditional rice cooking with a 1:6 water-to-rice ratio after five washes reduces inorganic arsenic by 20–39% compared to 1–17% reduction with rice cooker methods using a 1:2 ratio, indicating that water volume and discarding cooking water are key factors in reducing the most toxic form of arsenic in rice.
When rice is washed multiple times and cooked in a large amount of water, the inorganic arsenic dissolved in the grain moves out into the water. When the water is poured out, the arsenic is removed from the rice entirely, leaving behind less of the toxic substance.
What the research says
1 studyCooking rice in lots of water and pouring out the water after cooking washes away more of the harmful arsenic than cooking it in just enough water to soak up. This study proved that the old way removes more poison.
