If a Catholic consumes animal blood, through blood sausage or just directly, do they have to go to confession?

I drink animal blood strictly for health reasons. As far as I am concerned, it is integral to being **extremely healthy**, and not just moderately more healthy than normal. I'm not particularly interested in debating the merits of that perspective here. What I am interested in is how that affects my Catholic Faith. Some have mentioned that there is a reaffirmed prohibition on the consumption of blood in Catholicism: > Acts 15:20 "abstain from things polluted by idols, from sexual immorality, from things strangled, and from blood." But the reading of that being literal seems to miss the mark. It seems to be more about the ritualistic or symbolic blood or Cannibalism, rather than say "Korean Blood Sausage" or "Blood Pudding" or drinking that from a freshly butchered animal. I am not sure if I am prepared to put my personal health below Catholic teaching. If they forced me to be a vegetarian for example, I simply would not convert, or rather I would convert with every intention to break that hypothetical commandment every day. So for Catholics, what are the relevant technicalities to my dilemna here? If I were to become a Catholic, and then subsequently consumed animal blood for health reasons, would I then have to go to confession? Could I be excommunicated from the church for doing so insolong as my genuine belief was that this was for my health and longevity? Obviously there is blood in a rare steak; but I have not heard that the consumption of this as being a problem in Catholicism. Has this been ruled against officially or included as part of their catechism in any particular context?
