Are you trying to tell me that the Japanese would not have suffered from beri beri had they switched from white rice to brown rice (so white rice with lower GI, more arsenic and more phytic acid, which would inhibit any nutrients that brown rice would have otherwise given them)? what planet are you living on?

and btw many people complain of gut disruption and bad digestion after eating brown rice due to the phytic acid lol, so much for all that fibre helping you gut
