Since it's the tenth draft, many scenes and bits of dialogue were cut during the writing process and Neil Gaiman explains about those cuts and why they were made :
Anything that wasn't moving the plot forward has gone. Lots of interesting chatty background conversations in the TARDIS, gone. Lines of dialogue that were fun in themselves but weren't really needed? Gone. And the food scene? Very gone indeed. It's been gone since draft six. Given that it's not there any longer, and that that tells you absolutely nothing about the story except that it now doesn't have a scene with a bowl of food in it, I thought I'd borrow it back from Lucien's library.And here is the scene that was cut from draft six, in which the Doctor has been given something possibly alien to eat :
AMYIs it something people can eat?
Shouldn’t you scan it with your screwdriver or something?
THE DOCTORWhy would I scan food with my screwdriver?
AMYSee if it’s safe?
The Doctor leans over, dips his finger into his bowl, tastes it.
THE DOCTORSome unusual trace elements, smidge too much background radiation, but, yeah, very yummy.
Amy is about to try some of his food... he stops her.
THE DOCTOR (cont’d)No. Don’t put it in your mouth.
AMYNot for humans?
THE DOCTORNot for you. Tastes like Marmite on socks.
