In what ways?
For one their dairy cows aren't allowed to be injected with hormones Prooven to cause cancer and mental issues in baby's who were exposed to milk in the womb.
You can read more about it but I'm on my phone and cant cite sources.
This hormone has been banned in Canada and Europe to give to dairy cows, but here we still do it.
Also we spray our foods with deadly pesticides than also cause cancer. I'm not sure if Canada uses what we do, but our pesticides aren't really safe for human consumption, they cause cancer too and because nobody has died directly from pesticide poisoning they still say its safe.
You also have the widespread use here of high fructose corn syrup which is our leading cause for obesity, aside from people shoving whatever they want in their mouths. If we took everything with corn syrup and either changed it to sugar, or took it out compeletly, we would still have an obesity problem because people are uneducated about proper health, but we would have far less people who are morbidly obese and a lot less people who are overweight as a result of soda, snacks, and everything else we eat that contains it.
Government really doesn't care to regulate what is put on our plates. You see a lot more people having their own gardens, snacking on nuts and fruits instead of chips, and cutting soda back because the population is starting to realize the poison that we are fed.
I'm not a vegitarian, and I love fast food, I love burgers and fatty foods and soda. But instead of denying myself the foods I'm addicted too (yes the majority of us are addicted to these foods) I allow myself to have a soda when I go out, I allow myself to eat some chocolate every now and then.
I cant live off a full raw organic diet, but I do what I can to be as healthy as I can in this world we live in. America is really bad about what we eat, and our government is hardly stepping in and doing something about it. That's why we are obese, and Canada, Europe, and a lot of Asian countries don't have that problem. their government does better at protecting the food that they consume.
