Welcome to the world of being a mom. Some of mine never slept through until over a year. The problem is not that she is hungry, she has developed a habit of waking up. Even adult do it. You will have to train her not to expect you to come in whenever she wants. As long as you are sure that she really doesn't need anything, don't go in her room, and she will learn how to comfort herself and fall asleep on her own. It's a very hard thing to do, but after a time pays off for the both of you. Good luck.
As a side note, make sure you are not trying to make her sleep too much or too little. Check for the recommended amounts of sleep time for naps and nightime sleeping.
