I bought a bag of brown Basmati rice a few days ago. When I opened it, I found that about a quarter of the grains were green/greenish. Not clumped together like mold, just green grains. Is it safe to eat? Also, while we're on the subject ... Anyone know which variety of rice has the least arsenic? And which has the lowest glycemic index? Do you have any other info about rice you'd like to share? Thank you! .
