Is it extra protein, if they lived only off the rice in the bag? Presumably all the protein inside of them came from rice that would have otherwise been there.
I guess it helps digest and synthesize some of the proteins for you.
We eat grazing animals because they turn grass into muscles (proteins). It's similar for insects. That said, I don't know how the protein amount in one insect compares to the protein amount in rice.
