I have this weird thought that God gave us "cheater" foods, foods packed with protein and nutrients that we could use to supplement our diet, because He knew that it would be hard for us to cultivate our food (thru the curse). Those foods that are weird to eat: milk, eggs, honey... weird because milk is for baby goats and cows, eggs because those are for baby chicks, and honey, well, for baby bees.

And on the other hand, I think God warned us not to eat some foods because they are harmful to us. Included are animals that are scavengers like pigs, shellfish, certain birds.
