Rice Bran - National Nutrition Articles Rice bran is the hard outer layer of rice grains that can be left intact and milled along with the rest of the grain to produce brown rice. The bran is not the same thing as the rice husk, which is not used as a food source. Rice brain can also be separated from the rice and milled to create a source of fibre, essential fatty acids, vitamins and minerals. In fact, the rice bran contains over 60% of the nutrients contained in rice. The remaining grain after the bran is removed is commonly known as white rice. https://www.nationalnutrition.ca/articles/supplements/rice-bran/ #ricebran
