Good question, you seem to be just trying to stir up an emotional argument for no reason. Nobody said he should give it up. Someone simply pointed out that he doesn't need it like he claims he does.

Try it. Taste isn't just a case of "this contains calories so it tastes good". I like the taste of broccoli, and it has very little sugar and fat. Many people have the experience of not consuming milk for a while, then finding they don't like it any more.
