How would you survive if everything eadible could scream? Also, not sure why the screaming part is important. Plants are alive, too and they do feel pain. They just can't express this, similar to autists.
You'd still choose plants, because otherwise you're eating animals that themselves must feed on plants. Even from a coldly mathematical perspective you cause less suffering eating plants than animals.

That would certainly change the conversation. But given that there is dubious support for plants "feeling" pain in a sentient way, I don't see much reason to entertain it.
That said, my diet is mostly fruit, nuts and seeds anyway.
