My family would do this to me too, I moved out with my brother who ate crap all the time. I finally said... I am cleaning out this place and we are going Paleo. I threw out all pasta bread grains and processed food. Funny thing is my brother now follows the diet because he eats what I make and doesn't complain. If he wants something bad he has to go out and get it himself which is rare. Try getting your family to start eating better with you. Or cook your meals for yourself
