why not black rice and black rice bran?"

"Black rice bran would be a unique and economical material to increase consumption of health-promoting antioxidants."

The scientists explained that pigments in black rice bran extracts range from pink to black.
In the study, the researchers tested black rice bran grown in the Southern United States. Although brown rice is the most common rice variety produced worldwide, Xu said the study results suggest that black rice bran may be healthier than brown rice bran in terms of antioxidants.

"If berries are used to boost health, why not black rice and black rice bran?"
Xu and colleagues analyzed samples of black rice bran from rice grown in the Southern U.S.
Black rice is rich in anthocyanin antioxidants, substances that show promise for fighting cancer, heart disease, and other health problems, Xu says.

He adds that food manufacturers could use black rice bran or bran extracts to boost the health value of breakfast cereals, beverages, cakes, cookies, and other foods.
Black Rice vs. Brown Rice
White rice is made when rice is milled more than is done for brown rice; the bran is also removed, Xu says.

So black rice bran may be even healthier than brown rice, Xu says.
