Thai Brown Rice is whole grain rice with the edible brown (or bran) layer left on the rice seeds. It is very nutritious - a good source of magnesium, phosphorus, selenium, thiamine, niacin, vitamin B6, an excellent source of manganese and high in fiber. If you observe Thai brown rice you can find a few varieties of brown rice. Certain types keep the entire bran layer while others, are partially polished and leave some portion of the bran on the rice seed. It has a mild, nutty flavor, and is chewier than white rice. Thai Direct's frozen brown rice is freshly made, microwave ready in 3 minutes.
