Acts 15:28, 29: “The holy spirit and we ourselves have favored adding no further burden to you, except these necessary things, to keep abstaining from things sacrificed to idols and from blood and from things strangled [and from fornication. If you carefully keep yourselves from these things, you will prosper. Good health to you!” (There the eating of blood is equated with idolatry and fornication, things that we should not want to engage in.)
Animal flesh may be eaten,but not the blood
Gen. 9:3, 4: “Every moving animal that is alive may serve as food for you. As in the case of green vegetation, I do give it all to you. Only flesh with its soul—its blood—you must not eat.”
Any animal used for food should be properly bled. One that is strangled or that dies in a trap or that is found after it has died is not suitable for food. (Acts 15:19, 20; compare Leviticus 17:13-16.) Similarly, any food to which whole blood or even some blood fraction has been added should not be eaten.
