Does she mind what to eat? In fact, she can't feel anything now, as if she has fallen into a strange loop where nothing seems to matter to her, except when Atlas Hallow comes close, she becomes very sensitive.
All of her senses are gone; music is no longer melodious, colors are no longer dazzlingly attractive, even delicious food tastes like wax in her mouth. It seems all the lost feelings have concentrated on Atlas Hallow, like a huge invisible black hole, slowly sucking away her senses toward the external world, focusing all her feelings onto him.
She's more sensitive to his every move than ever before, no matter how small. She doesn't know why her feelings are so intense, perhaps because of her little child who has eyes just like his, but whereas the child's eyes were as clear as black crystal, Atlas Hallow's eyes are pitch black, revealing nothing, just an abyss.
