Rice is such an important food in some countries that "to eat" means "to eat rice." Nearly half of the people in the world get approximately 50% of their calories from rice.
There are many varieties of rice, such as arborio, jasmine, and basmati. It also comes in red, black, and purple, with the colors coming from pigments in the bran layer.
Brown and white rice are the same grain, just milled differently. The presence of the bran layer makes brown rice more nutritious than white, although some white rice is fortified.
Brown rice can help people with diabetes control their blood sugar.
