Black rice, also known as purple rice, is a range of rice types of the species Oryza sativa, some of which are glutinous rice.
Glutinous rice, also known as sticky rice, does not contain amylose, which, in addition to making rice sticky, helps slow down digestion and lowers insulin levels.
However, because black glutinous rice is unprocessed, it retains more of its other nutrients, making it a healthy food choice overall.
