Red rice is a variety of rice that is colored red by its anthocyanin content. It is usually eaten unpolished or partially polished, and has a red bran layer, rather than the more common pale brown. Red rice has a nutty flavor. It has the highest nutritional value^[quantify] among rices eaten with the bran intact.^{[citation needed]}

Health claims

Some strains of red rice, when eaten dehusked (analogous to ordinary brown rice), has a lower glycemic index compared to white rice (Basmati and Jasmine), which is polished. However, research also indicates that polishing red rice removes this difference.^[1]

Red rice contains higher antioxidant levels compared to white rice,^[2] though what they actually do in the human body is unclear.

Dehusked red rice is also a richer source of iron, magnesium, calcium and zinc than white rice.^[3] The same can be said of ordinary brown rice.^[4]
