Really, it’s not much better than white rice, and has less fibre, protein and fat than all the other choices Raster mentioned, with much more starch and a considerably higher GI. Not very impressive since it tastes like crap and has a terrible texture when compared with white rice.
If there weren’t other options, maybe you could justify small quantities of something like this, but why not try buckwheat, millet, oat bran or rice bran? The prebiotic properties of these foods will actually contribute towards your recovery, whereas brown rice offers little more than a quick carb fix.
