Having travelled to some northern communities first-hand, I can say that the intent is there. There are programs to teach individuals and families about healthy living. However, it's very difficult for individuals to leave, for example, a workshop on healthy living and healthy eating, and go to the grocery store where a quarter of a watermelon is almost $16, two apples are $4, but an extra large chocolate bar is 99ยข.
Paired with the programming that I think is already there, and if resources are provided to be able to deliver these as needed, I think that the other side of it has to be policy that will impact what is available and at what cost because it's very difficult to tell somebody to eat healthy, but give them no access to those healthy foods.
