The Claim

Rinsing rice in excess water and discarding the cooking water reduces arsenic content by 42.3%, lead by 42.9%, and cadmium by 27.6% compared to the conventional Kateh method, which reduces arsenic by 26.9%, lead by 26.9%, and cadmium by 20.9%, indicating that cooking method significantly influences the residual concentration of toxic metals in cooked rice.

In plain English

Rinsing rice thoroughly before cooking and discarding the water lowers the levels of arsenic, lead, and cadmium in the cooked rice more than the traditional Kateh cooking method.

See the scientific wording

Rinsing rice in excess water and discarding the cooking water reduces arsenic content by 42.3%, lead by 42.9%, and cadmium by 27.6% compared to the conventional Kateh method, which reduces arsenic by 26.9%, lead by 26.9%, and cadmium by 20.9%, indicating that cooking method significantly influences the residual concentration of toxic metals in cooked rice.

Why this might work

When rice is cooked in a large amount of water and the water is thrown away, the toxic metals inside the rice grains dissolve into the water and wash out, leaving less metal behind in the cooked rice.

  1. Study: The reduction of toxic metals of various rice types by different preparation and cooking processes - Human health risk assessment in Tehran households, Iran.

    Boiling rice in lots of water and throwing out the water takes out more harmful metals like arsenic and lead than cooking it in just enough water to soak up. This study proved it works better.
