The Claim

Cooking rice with a 1:6 water-to-rice ratio after five washes reduces cadmium content by 35% and lead content by 27%, and health risk assessments indicate no appreciable noncarcinogenic or carcinogenic risk from cadmium or lead regardless of cooking method, with arsenic identified as the primary toxicological concern in Bangladeshi rice.

In plain English

Cooking rice with six parts water per one part rice after five washes reduces cadmium by 35% and lead by 27%. Health assessments show no significant risk from these metals regardless of cooking method, but arsenic remains the main toxic concern in rice from Bangladesh.

See the scientific wording

Cooking rice with a 1:6 water-to-rice ratio after five washes reduces cadmium by 35% and lead by 27%, but health risk assessments indicate no appreciable noncarcinogenic or carcinogenic risk from these elements regardless of cooking method, suggesting that arsenic is the primary toxicological concern in Bangladeshi rice.

Why this might work

Washing rice multiple times and cooking it with a large amount of water removes cadmium and lead by dissolving them into the water, which is then discarded. The metals do not bind tightly to the rice grains and are washed away before or during cooking.

  1. Study: Removal of Toxic and Essential Nutrient Elements from Commercial Rice Brands Using Different Washing and Cooking Practices: Human Health Risk Assessment

    Washing rice five times and cooking it with lots of water removes about a third of cadmium and lead, but even without doing that, these metals aren’t harmful. The real danger in Bangladeshi rice is arsenic — that’s what you need to worry about.
