A study by Consumer Reports Magazine says eating rice once a day can drive up arsenic levels in your body by 44 percent. A second portion could lead to a 70 percent increase.
Researchers say the worrisome levels of inorganic arsenic are linked to lung and bladder cancer.
Nutritionists say what's important is to eat rice and rice-products in moderation.
"This doesn't mean people should stop eating rice,” said nutritionist Trish Kazacos, “or even quinoa or barley."
Consumer Reports indicated that it's important for young children and infants not to eat more than one serving of rice or rice products per day.
