The deep black or the purple hue of the black rice is a marker of its high antioxidant properties. Similar to blackberries and blueberries, that appear deeper in colour because of their high content of anti-oxidants. The outermost layer of the grain (the bran and the hull), contains immense amounts of the antioxidant-anthocyanin. In fact the amount of anthocyanin contained in black rice is higher than any other grain, including brown rice, red rice, red quinoa, or other colored whole grain varieties.

White rice and other refined grains are stripped of their high nutrient content and beneficial properties in the milling process. Majority of the nutrients of rice are present in the outer layer, the hull and the bran, which are only retained in whole grains. Since black rice doesn't undergo any refining or processing, it is able to retain its antioxidants, but also vitamins, minerals, and fiber (5 g / 100 g).

Black rice also contains important Vitamin E, which is useful in maintaining eye, skin, and immune health.

To ward off the risk of diabetes and obesity, it is advised to consume whole grains instead of just refined carbohydrates. The entire bran of the grain is where the all the fiber is stored in the black rice. The fibre is able to help glucose (sugar) from the grain to be absorbed by the body over a longer duration of time, (Since fibre take the longest to digest), thereby maintaining consistent sugar levels. 

For people battling obesity, black rice is the best variant of rice to consume. Full of fibre, black rice not only gives you the feeling of being full, thus preventing overeating; studies show that the rice variant can also help prevent insulin resistance, which is often linked to the risk of developing diabetes and obesity.
