The roots of food

Where does our food come from and how do we know this. Does the label on the package ensure truth, or can mommathon grocer switch labels. And don't we all want the prettiest fruits and vegetables - how much grocery produce goes to secondary use, because it won't sell retail. This article bring up some interesting points, but i can't help but think that group certification is a form of circling the wagons for the in crowd. If i as a farmer am willing to place the food on my own dinner table, that should be certification enough.
