Whether you buy rice at the grocery store or order a side of it while dining out, do you prefer brown rice or white rice? Or do you exclusively choose brown rice over white rice because you want to eat healthier, as brown rice contains more nutrients and fiber? Well, the answer to this question is not as simple as you might have thought, as it ignores a potential food safety concern.

According to new research from Michigan State University, published in the journal Risk Analysis, brown rice was found to contain higher levels of arsenic content and inorganic arsenic concentration than white rice among American populations.

While there are no major health risks for the general American public, there are potential health concerns for infants and children under age 5, as they consume more food relative to their bodyweights than adults.

Specifically, after comparing the nutritional aspects of brown and white rice, Wu and Scott used data courtesy of the “What We Eat in America” database of the U.S. Environmental Protection Agency and Joint Institute for Food Safety and Applied Nutrition to calculate average daily intake mean rice values for both brown and white rice.
