Some have atrocious ingredients. But some are just rice and sea salt. Although most use whole grain brown rice.
Do you think the whole grain aspect of some puffed rice is all that terrible? I ate one the other day and these things are as light as a feather. Incredibly bland and boring by themselves, but the crispy-ness aspect is sometimes appealing to use as a vehicle.
Do you ever eat rice cakes? If you do, what do you eat your rice cake with?
