^ Well, that's probably because we really don't know. We didn't see Touka using her kagune in the first half of the fight with Tsukiyama, but we don't know if that was because eating human food = damage to Kakuhou or she simply didn't have the strength to use her kagune as a result of her weakened condition.

In terms of the question about pregnancy, I'd say your idea is incredibly far-fetched simply based on how pregnancy works. A woman eating something that hurts her body is going to hurt the baby as well. So if she's poisoning herself, she's poisoning the baby as well, through the shared blood supply.

In terms of the whole issue with female Ghouls not being able to give birth to half-Ghouls, it sounds like an issue with the Immune System. Sometimes in real life, the mother's immune system will recognize the fetus as "foreign substance" and attack it. Probably, it's the same thing with the female Ghoul -- her body isn't recognizing the cells as "pregnancy" but as "nutrients".
