Darker Rice Richer in Antioxidants

Scientists in Portugal studied different varieties of rice to determine which components might be linked to lower incidence of some chronic diseases in rice-consuming regions of the world. After building a database compiling information from 316 papers, they determined that black rice had the highest level of antioxidants, followed in descending order by purple, red and brown rice. Based on their findings, they advised that “rice should be preferentially consumed in the form of bran or as whole grain.” They also found, however, that many other cereal grains had higher levels of most antioxidants than rice.
