I'm a bit lost with the comments about the amount - a percentage of 80 means that if you eat 100 gm, 80 gm is carb, if you eat 50 gm, 40 gm is carb, and for 25 gm, 20 is carbs - it is a percentage.....
Eating brown rice mans that the impact is just a tiny bit less - personally I'd rather eat something with a bit of colour and flavour than any sort of rice.
How about eating a salad with coleslaw walnuts radishes celery tomato beetroot, finely sliced onion, a bag of salad, sweet pepper - rather than a spoonful of rice?
I know which I'd opt for. Don't forget the EV olive oil and a nice wine vinegar and some herbs as dressing.
