Rice of different varieties forms the staple food of more than half of the population in the world and is the leading cereal crop in many developing countries of the world. About half of the world population consumes rice as their major source of carbohydrate however it is also consumed as a source of protein in many countries. Rice comes in many shapes, sizes and color and thus its nutritional quality, cooking and uses vary accordingly. It is not only the white rice which contributes to these production figures, but it are available in many colors and pigments including black, purple, brown and red. The yellow, green, brown, red, purple and black colors of the rice have neutraceutical properties and hold the potential to promote health and improve metabolism. Black rice, also called "emperor's rice," has a thin layer of black bran, due to the presence of the purple/ black pigment biochemically termed as 'anthocyanin'. It is a rich source of antioxidants along with other nutrients including B vitamins (thiamine, niacin), vitamin E, magnesium, phosphorous, iron and dietary fibers. Similar to normal white rice, pigmented/ black rice is also glutinous and is relished for its nutritional significance of being low in fat, sugar and salt it is also free from gluten and cholesterol. Not only the historical evidence but modern research findings also support the claim of pigmented rice being 'super food' of twenty-first century. It has wide health benefits including lowering risk of obesity, anti-ageing, anti-cancerous, anti-diabetes and many more. Its consumption even in limited amounts acts as a savior from many serious diseases and illnesses. Due to its nutritional composition and various health benefits, it is considered as a functional food. The presence of anthocyanin, the pigment that imparts it a specific colour and holds antioxidant properties supports health and longevity. The present review reflects the nutritional profile and significant benefits of pigmented rice including its food uses so that the commodity can be popularized and utilized by the population for gaining various health benefits.
