I didnt quite get it when Edward ব্যক্ত to Bella in the fist movie.."It's not like drinking ur blood for instance"

If I understand আপনি correctly Edward means that drinking animal blood is not the same অথবা as good as drinking a human's blood, namely Bellas. He's comparing it to how it would be for humans eating tofu. It's খাবার and it sustains আপনি but it's not the same as eating something else আরো appealing. So while Edward drinks animal blood he would much rather drink human blood especially Bellas.
