Studies Claim U.S. Rice Has Less Poisonous Arsenic

May 2, 2008

According to new studies published by the journal Environmental Science and Technology, United States rice contains more methylated arsenic compared to the rice from Europe and Asia which has more inorganic arsenic. Arsenic is less poisonous in its methylated form.

The two studies entitled “Arsenic Speciation in USA Grain and Implications for Human Health” and “Estimating Normal Levels of Total Arsenic in Rice Grain”, revealed that arsenic speciation varies with the type of rice. Moreover, scientists from Cornell University were able to categorize rice into dimethyl arsenic acid (DMA) and inorganic arsenic types. Results of the studies show that DMA rice type is likely to be less of a health risk than the inorganic type.
