Meh, I'm still not convinced its particularly better. Scientific studies are one thing but personal, practical application in my own dieting is more credible IMO. White digest much easier and faster (which is important as I usually like to consume it pre and post training). Sits easier in the gut, and doesn't cause as much bloat as brown from my own experience (and many others).
Though brown may be shown to have more nutrients and minerals than white, I feel its very negligible from the cosmetic perspective of looking like a bodybuilder (which is the premises behind my own eating) especially when considering the amounts of nutrients and minerals that are already consumed through the other macro sources eat'n in a bodybuilding diet.
