You won’t find even a single grain of rice at the home of Aubrey Graf-Daniels. The grain is off limits for dinnertime.

On a recent night, she was busy preparing the dish for her family. “I stopped eating rice about 2 to 3 years ago because I'd heard about the arsenic,” she told CBS News.

In recent years, there's been concern about this contaminant in rice. Arsenic is to cause health problems. The U.S. Food and Drug Administration has been monitoring levels for decades and has said the arsenic levels found in rice products are too low to cause short-term issues.

But research is also finding that arsenic can have a longer-term impact on health, and is linked to certain cancers and heart disease.

“The number of health effects we contribute to arsenic has grown over time,” Dr. Joseph Graziano said. 

Graziano’s lab at Columbia studied arsenic in water and its effects on pregnant women. He found higher levels can be particularly problematic for the newborns. “We’ve learned arsenic can change the DNA,” he said. “It may influence the health outcomes later in life.”
