Regarding what is appropriate to eat, well, every moving thing that is alive, the Bible says. One restriction is present, though, not the blood of anything. We now know that specifically through blood, diseases are spread. The source of HIV was from Chimpanzee meat consumption. The source of Ebola appears to be from Fruit Bats. Now, how were these foods prepared? Researchers should look into that.
Gen 9:3 “Every moving thing that is alive shall be food for you; I give all to you, as I gave the green plant.
Gen 9:4 "Only you shall not eat flesh with its life, that is, its blood. (NASB)
