Context: I ' m going to take him to an ENT and I ' m also going to try to get things better on the homefront . He has got to start eating a more varied diet . He can not live on dairy products ( especially because if we could get a phlebotomist to take his blood and get it allergy tested I bet it would show some dairy intolerance ) , especially cheese . Or cheese on top of cheese .

Question: Why ca n't he live off of dairy products ?
Options:
0. You have to have a well - balanced diet in order to be healthy .
1. Cheese by itself might be fine , but cheese on top of cheese is not good at all .
2. He is an ENT which stands for Eat No Tomatoes , so he can only eat cheese .
3. He is lactose intolerant so it hurts him to eat cheese .
