Having a beer or two is not "sacrificing your health". And if liking the taste of alcoholic drinks counts as being "programmed", then so does every other preference and desire human beings have.
But it is, alcohol is very poisonous; which is why you feel like shit and loose your memory when you overdo it, and why it's so hard to hit just the right amount of poisoning to feel funny without feeling sick.
Drinking poison that tastes like shit doesn't really happen without outside pressure. That's not true of every other preference and desire.
Having a beer or two occasionally won’t kill you. But making it a working routine, even with such a small quantity that won’t even make you drunk, will definitely have some impact in your health in the long-term.
Oh, I've drunk more quality beer than most. Stop for six months and try again if you don't believe me, once the body has detoxed it's going to start putting up a fight. I can't even smell alcohol these days, even at the levels of normal beer; it smells like gasoline.
Is it really worth sacrificing your health for? It doesn't even taste nice once you cut through the cultural programming to pretend otherwise.
