There is no uniform definition of the classification of food flavors and there is insufficient evidence on this. Black rice is neither cold nor hot, it is a food and can provide some nutrients to the body when eaten in moderation. Black rice is a food, not a drug, and cannot be used to treat diseases. Black rice is rich in carbohydrates, protein, zinc, iron, phosphorus, potassium, magnesium, selenium, also contains crude fiber, fat, niacin and other nutrients. The high content of carbohydrates can provide a source of energy for the human body, to a certain extent, to help maintain the normal life activities of the human body. Therefore, eating black rice in moderation is beneficial to human health, but too much eating is easy to increase the burden on the gastrointestinal tract, bloating and other discomforts.
