Some strains of red rice, when eaten dehusked (analogous to ordinary brown rice), have 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
