Rice has recently been in the spotlight for containing trace amounts of arsenic from the soil and water in which it grows. To reduce the arsenic that may be in rice, you can soak rice in water for 15-30 minutes before cooking and discard the water, or rinse the rice through a mesh colander or strainer until the water runs clear. White rice tends to have less contamination than brown rice. I'd recommend not eating rice every day, and maintaining a varied diet to reduce exposure.
