Just to take up Barb's point a little bit, I would go back to the issue of education. Somebody once said “You give me the child, and I'll give you the man”. Essentially, if you go back to school and can become a health-literate graduate of high school, by which I mean someone who understands enough to navigate the information that's out there, you've probably done as much as you can.
The background to healthy eating is sometimes actually economic. I've worked in areas where it is cheaper to buy two bags of chips and a can of Coke than it is to buy a glass of milk and an apple. When you are on a very limited income—and I come from a province whose average income is lower than the Canadian average, and the population I refer to has a lower average income than that even—that makes a huge difference. You go with what will fill your belly on that day, not necessarily what's going to be good for you over the long term. A hungry kid at school is not going to learn, either, so a school breakfast program might be something you would want to think about.
I'm talking outside my field of expertise. I'm a general surgeon. I'm a disease expert, and I've gone right back to now talking about education and clean water and those kinds of things. That's just my two cents' worth, but I'm off my home patch.
Maura, on the other hand, is right on her home patch.
