I’m not entirely sure why Isabel wants to be difficult about what she eats. The meatballs in her spaghetti are not going to hurt her. That macaroni and cheese is actually good and contrary to belief does not contain flesh eating bacteria or alien worms, and the yellow sauce is really just cheese. Besides, apparently she has ingested her own pee in utero.
