I read something interesting about high GI vs low GI foods that I didn't know [1]. The TL;DR "The GI value of a food is determined when it’s eaten in isolation after an overnight fast. As in, this is how this food will affect your blood sugar when it’s the FIRST and ONLY thing you’re eating after a full night of not eating anything."
So the whole high GI is bad thing taken to the extreme e.g. clean eating, is probably completely blown out of proportion. It's measured in a very isolated ring-fenced setting that most likely doesn't apply to how you eat food anyway. Put bluntly: don't fret too much about eating white rice instead of brown rice (especially if you're counting macros).
