People adapt to what they know
I laugh at all the experts while I'm standing in the local fast food joint. Proper diet habits start with training mom and dad who pass on those habits to children at a very young age. Children eat through life what is comfort food. That is what mom and dad provided them when they were very young. My children love salads and veggie plates. Why? Because it was the treat they got when they were young. They also received candy and soda but by that time there habits were formed and those treats were on the same footing as the healthy ones. Two boxes of hamburger helper with the cheap meat will make you fatter then the soda. Want to fix it, teach it, and teach parents how to eat healthy. Otherwise you are just passing the behavior on to generation after generation and the problems multiply. Look at the family; you can see the eating habits they have from a block away. A lifetime of habits isn't going to be changed by an increase in cost. Ask the folks driving the SUV's and big 4x4's. Gas prices stink but, can't take the Mini Cooper hunting, mud running or to pick up plywood at the local hardware store! At least not yet!
