Speak unto the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat. Leviticus 7:23
Occasionally, skeptics like to pick this verse to show how ridiculous the Torah is. How can anyone eat meat without eating fat? Are you supposed to trim every bit of fat from every cut of meat? You only have to look a couple more verses down to see that that is not what God meant.
For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto the LORD… Leviticus 7:25
The particular fat that is offered by fire is the fat and glands around the kidneys and other internal organs, not the fat that is commonly found around muscles.
The command against eating blood has a similar problem, but can’t be resolved by reading a little further. It can, however, be resolved by thinking a little further. The Torah was not written for morons. It’s not complicated, but it was written for people who are at least capable of thinking their way out of a paper bag. If you follow the Torah’s instructions for killing and bleeding an animal, then whatever blood is left in the tissues is fine. Like the yeast that lives in the air at Passover, there will always be some blood in meat, and there’s nothing you can do about it. Stay away from† boudin noir, but don’t worry about a rare steak.
