the problem is,you automatically are assuming that
1) people on medicaid are not having a healthy lifestyle. No every one on medicaid does not spend their days at fast food sitting in front of a tv. plenty of them do the best they can.
2) you're assuming they don't know about proper nutrition. They are poor not stupid. My dh knew a boat load about nutrition and he was amateur cyclist. he still got luekemia. My mother was a very healthy women up until the time she got breast cancer.
many folks on medicaid are working poor with high school educations. many folks living in poverty are poor but still read labels and try to eat as healthy as possible.
Not everyone who is poor doesn't know about healthy eating. There are lots though who do not. Is it wrong to educate them? Is it wrong to want them to have a healthier lifestyle?
