There isn't a huge difference. More fiber, more vitamins, magnesium, etc.
Nothing massive, especially compared to enriched white rice. But it's still better so if you can get used to it you might as well switch.
but isn't it mostly the non-soluble type fiber? I forget which one is better--fat soluble or whatever. But I seem to remember it being pointed out that this specific benefit was no benefit b/c you aren't going to metabolize it anyway.
rice-a-roni.
The white stuff has no flavor.
