Brown Rice: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Brown rice is the dehusked seed of the rice plant (Oryza sativa). It contains nutrients such as fiber that are often removed from white rice.

Brown rice retains the bran, germ, and endosperm from the seed of the rice plant. This means that brown rice contains higher amounts of fiber, unsaturated fatty acids, protein, minerals, vitamins, and starch than white rice.

People use brown rice for diabetes, prediabetes, obesity, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse brown rice with rice bran, rice protein, black rice, or red yeast rice. These are not the same.
