Question: Does Film Taste Affect the Quality of the Film?

I know...this is a very odd question. To be honest too, I don't think that I'd ever sit there and lick a roll of film no matter how smitten I am with well exposed Portra 400. But the folks over at Not Another Gear Review decided "Screw it, why not?" Yes, they decided to see if the taste of a piece of a film affects the image quality in any way, shape or form. Why? Science? Funsies? YouTube hits? Being featured on a site like this one?
