The Claim

Boiling rice in water or soaking it in hot water results in arsenic concentrations in the rice water exceeding the World Health Organization’s drinking water limit of 10 ng/mL, with measured levels of 15–19 ng/g in rice water derived from white and jasmine rice, which constitutes a health risk when consumed regularly.

In plain English

Boiling or soaking white and jasmine rice in water releases arsenic into the water at concentrations higher than the World Health Organization’s safety limit for drinking water, and consuming this water regularly exposes people to unsafe levels of arsenic.

See the scientific wording

Boiling rice in water or soaking it in hot water results in arsenic concentrations exceeding the World Health Organization’s drinking water limit of 10 ng/mL (10 ppb), with levels reaching 15–19 ng/g in rice water derived from white and jasmine rice, posing a potential health risk if consumed regularly.

Why this might work

When rice is boiled or soaked in hot water, arsenic stored inside the rice grains dissolves into the water, making the water contain more arsenic than safe drinking limits.

  1. Study: Rice Water—More a Source of Nutrition Elements or Toxic Arsenic? Multi-Element Analysis of Home-Made (Natural) Rice Water and Commercialized Rice-Based Products Using (HG)-ICP OES

    When you boil or soak rice in hot water, it releases arsenic into the water—more than if you soak it in cold water. This rice water can have more arsenic than what’s considered safe to drink, so it’s not safe to consume.
