It’s a cereal killer. 🙂
Rice cereal is a popular first food for babies. It’s also kind of high in arsenic, says the Food and Drug Administration, so if your kid gets a steady rice cereal diet, it’s time to diversify.
Boiling it and discarding the water (like how you make pasta) reduces the arsenic content, so that might help. The FDA’s fact sheet has some more info. I’ve covered arsenic in rice in the past.
