Before I get to the reasons you might want to think about it, here are two opinions I'm not going to consider at all:
- God doesn't exist, so it doesn't matter anyway. This is both untrue and off topic.
- God never cares about what people eat. You may argue that's true now but there certainly at least dietary laws in the Old Testament. It is not beyond God to care about what we put in our bodies.
- Black pudding is a kind of sausage, particularly popular in the north of England and Scotland. The reason I'm bringing this up is that it is made, in part, from pork blood.
- Pork is clearly declared allowable for Christians (including Jewish Christians) to eat, in Peter's vision (Acts 10). This is part of what might be called the ceremonial law of Israel (in the law revealed to Moses), which dealt particularly with setting the Israelites apart from the nations around them. As gentiles and Jewish new testament believers are united into one new humanity (the Church), these clean/unclean distinctions no longer exist.
- Restrictions on eating blood, however, do not solely belong to the ceremonial law. In Genesis 9, Noah is, for the first time, allowed to kill and eat animals - even ones that would later become unclean. Yet God bans him from eating animals with 'the lifeblood' in them.
- In Acts 15, the first Christian council, gentiles are recognised as belonging to the Church in the way I point out above. But they are specifically banned from eating blood (amongst other things).
- The early Church (post Bible times) seemed to follow this command as well.
