Is this rude?

I live with my hubby, my daughter (18 months) and a roommate/friend we all share food but I buy food out of my pocket to satisfy my cravings (15 weeks pregnant) is it rude to buy my goodies and food I want to eat and tell them to not eat it?? I get so irritated when I go to eat something I want and it's already been eaten.
