Many studies, including one in Environmental Health Perspectives in 2009, indicate that exposure to arsenic-contaminated food and water during pregnancy can also lead to miscarriage or low birth-weight and developmental difficulties in babies.Arsenic in rice is a real concern, but that doesn't mean you should cut this staple grain out of your diet. Be more choosey with the type and origin of your rice, always rinse and cook it with excess water, and be aware of how much you're consuming.
