Stupid question

Hello there. I've to know that it's a stupid question for somebody but it's my trouble. Where to find food ? Most (super)markets sell packaged food that I don't consider healthy : are rich in calories while poor in nutrients; pizza is a classic example in my Italy (where "Mediterranean diet" is utopia). It is also very tasky to prepare at home complete meals from ingredients which are however sold. Even I can't afford the purchase so my father broughts to me junk food which he considers healthy because he sees infamous trademarks. My father eats only breadsticks. Restaurants are worse and very very expensive so I couldn't know why they exist. I thought to search for a diet supplement but I discarded idea : as name suggest it may not be a food surrogate. It it the last resort to open a legal issue against my father and go to live from myself? It would happen in a very long time!!! Help me, especially you women.
