You missed my point, or something. Candy, sodas, chips and other junk foods are not less expensive than nutritional food. No, I have never had to subsist on ramen noodles, nor would it have entered my mind to do so. I was taught the old ways as a child and wouldn’t have even known what ramen noodles were. I did know how to hunt and trap game, grow food, and even go to the forest and get some possum grapes for grape dumplings for dessert. So, don’t chide me because you obviously misinterpreted what I wrote and have no idea about what I have had to “subsist” on.
I did not misinterpret what you wrote. My point is that it's not necessarily candy, soda, chips, and junk foods. While I agree that many are taking the path you mentioned, the fact is that it's not necessarily that way.
I did know how to hunt and trap game
The traps that allowed my family to survive have been passed down through the generations, and I still use my grandpa's rifle, but as the article states, the problem is with "...socially acceptable..." means of sustenance. It's awfully tough to run a trap-line or live off hunting or gardening these days, if one is in an urban or suburban setting (where the jobs tend to be). And heck, people thought I was joking when I was in grad school and mentioned eating squirrel.
So my point stands, it is difficult for many people to eat nutritiously, without obesity, on low income, even if they eschew "junk foods."
