Eating brown rice can lead to significant arsenic risk for children under five compared to white rice, according to research by Michigan State University (MSU) in the US. Arsenic is a natural component of the earth’s crust and is poisonous to humans and animals. Due to growing conditions, rice takes up nearly ten times more arsenic content than other grains. Rice is often grown in continually flooded fields, and wet soils can absorb arsenic favorably and transmit it to plants.
