LEV747 It is a negative commandment not to eat the kind of food eaten by a wayward and rebellious son for it as stated, You shall not eat over blood [this verse], which is understood to mean, "You are not to eat the kind of meal that leads to bloodshed"--and that is the food eaten by a wayward and rebellious son. This verse of Scripture is also an injunction not to eat [any flesh] of an animal before its life expires. It is also an injunction not to take any food before we pray.
