Are people aware of how poor the American food supply is?

Well I guess we should all just stop eating then. Last I checked we are eating a lot cleaner than we were 100, 50, or even 20 years ago. The food industry has standards and association's like SQF (Safe Quality Foods), ABI (American Bakers Institute) and GMP (Good Manufacturing Practices) and the ultimate authority the FDA (Food and Drug Administration). Any one of those violations you mentioned would be cause for a loss of certification as well as a HEFTY FINE. You know the government doesn't pass up on the chance to issue a fine. So maybe you better double check your info and be sure your not talking about China.

Most of what you allege is either false or you misunderstand it. On the contrary, the American food supply has never been better or safer.

I don't know what's so bad about GMO.
So it's genetically modified. Big deal.
The FDA makes sure that the content of rat hair and such isn't extreme, and that shows because people would get sick if they ate raw rat junk, and yet we manage to stay healthy eating regular food.
Our epidemic in America is malnourishment and obesity (and the two can actually happen at the same time), but we've always known that MacDonalds is bad for us. The pop science uses the same terms a lot, but everything is still about fatty meat, sugary drinks, not enough vegetables.
You can live a long time eating regular, non-organic green beans and FDA graded Tyson meat.
People are in trouble just as much because of sedentary lifestyles, the unnaturally high stress lives we often lead because of financial woes, and other life-shortening events like, for example, crashing a motorcycle.

If you want to eat all organic, then I guess that's fine. You're not going to cut out the presence of extra bugs and rodent residue that way though. I used to work on an organic farm. I know the silly-*** methods they use for cleaning their vegetables.
Everything is all things, and we all die. Usually it isn't because of FDA approved food or a little rat guts. Ultimately, it's up to you whether you want to pay extra for organic or buy yourself a gym membership. If you manage your own garden, wake up early for a morning jog, and buy free range eggs, then maybe you can spend that money on an Xbox so you can sit for 5 hours a day and pretend to be a deadly assassin or something.

People care more about money than others health. Just how it is, sad world we live in.

I think a lot of people are becoming aware of it. I know many who are changing their diets but you even need to be careful with food labelled as organic, its sometimes a trick. My father always encouraged me to have my own garden and grow my own fruits and vegetables. He said, "Pretend you don't have access to the markets. What would you do? How would you feed yourself? Go from there." I swear if all of sudden we didn't have access to supermarkets and such, my dad would survive just fine. He grows his own fruits and vegetables, hunts and fishes, and he even has a well in our backyard he drinks from. I want to live this way.

I was looking into which regions have the most longevity and I do believe, besides other factors, it's linked to their diets, look at how they eat and live:

Yes, I am - that's why I bought a 55 acre farm and raise my own chickens, goats, a nice pond full of fish, and a 3 acre vegetable plot, plus 140 fruit trees of different sorts.

The sad truth is that the major supermarkets have so screwed over the farmers that they make so little profit, if they do, from their produce that they can't afford qualified workers or machinery

I think people are aware, that's why the mainstream supermarkets were forced to offer organic foods when they started losing market share to Trader Joe's, Whole Foods, etc. Do you know about carrageenan, carmine, l-cysteine? If not, research them, more disgusting stuff contaminating our food supply, disgusting isn't it!
