Purple rice and black rice are the same thing

From Google AI overview:

• Purple rice bran contains more phenolics
  
  According to a USDA publication, purple rice bran has three to 25 times more total phenolics than blueberries. 
• Purple rice bran contains natural antioxidants
  
  A study found that purple rice bran extract contains high amounts of natural antioxidants, including water- and lipid-soluble compounds. 
• Purple rice contains anthocyanins
  
  Purple rice is a source of natural anthocyanin compounds, which are major antioxidant compounds that protect against cellular damage. 

Blueberries are also a well-known source of antioxidants, and one cup of wild blueberries contains about 10 times the USDA's recommendation. However, blackberries and other berries may also contain high levels of antioxidants.

Purple rice and black rice are the same thing, but differ in color when raw and cooked:

• Raw: Black rice is black, while purple rice is also black.
• Cooked: Black rice turns deep purple when cooked, while purple rice also turns purple when cooked. 

Black rice is a type of Oryza sativa rice that's high in anthocyanins, an antioxidant pigment that gives it its distinctive color. It's also a good source of protein and fiber. Black rice is often sold as a whole grain, with the bran intact, making it technically a type of brown rice. 

Here are some other characteristics of black rice and purple rice:

• Flavor
  
  Black rice has a mild, nutty flavor. 
• Nutrition
  
  Black rice is a good source of protein, fiber, and nutrients like vitamin E, riboflavin, niacin, and potassium. 
• Origin
  
  Black rice is grown primarily in Asia, while purple rice is an heirloom variety of rice that's indigenous to Asia.

The black color of black rice is not due to dyeing; it is a natural characteristic of the rice. The color comes from anthocyanins, which are natural pigments found in the outer husk of the rice. Anthocyanins are the same type of pigments that give certain fruits and vegetables, like blueberries, red cabbage, and purple grapes, their distinctive color.

When you wash black rice, the water turns black because the anthocyanin pigments leach out into the water. This is a normal process, and the color is natural, not artificially added. The black color of black rice also indicates that it is a whole grain, with its husk intact, which preserves the nutrients and fiber.

Black rice, often referred to as "forbidden rice," is prized for its high levels of antioxidants, fiber, and various micronutrients, making it a healthy choice.
