Travel Channel should add a warning before airing "Bizarre Foods" promos

I like watching shows on Travel Channel, but I get seriously nauseated by the promos for the show "Bizarre Foods, America". Every commercial break, I am exposed to promotional advertising for this show, which includes animal guts, blood, and graphic images of animal mutilations. I would like for Travel Channel to air a warning before these promos air that would warn viewers that graphic images of animal mutilation and gore are going to be aired. This would  give viewers the opportunity to either change channels or turn their heads until the commercial is over.
