How do you guys separate lifestyle from religious beliefs?

A friend of mine asked me if I would ever be open to trying meats like beef and pork. I have no answer because I am not really sure if it is my religious beliefs or my pickiness to eat food which is infringing here. If it is the former, how do you guys navigate around it?

Like there are certain choices I would never make, like smoking or drinking because objectively they are bad for health. Not judging people who indulge, I'm just the designated driver of my group lol. So how can I be sure if I ever want to try these foods out?

Edit: I see some very interesting, insightful and polarizing comments here. But I got the gist, thank you!
