I agree that Trader Joe's meats and eggs are not ideal. They are, however, better than the supermarket. I don't buy my meats, eggs, or dairy from there. I do buy organic fruits and veggies, and they have a decent selection of organic frozen fruits and vegetables. The prices are pretty good too. It's like everything else, you have to look closely and read the labels. I can also buy some packaged foods that, although not what I would consider healthy, do pass as junk food for my kids, and they're happy. It keeps them out of McDonald's-and that's a start. It is a place where you can get some quick items if you are in a hurry, or forgot that important ingredient at the farmer's market.
Keep going, look and read. You will find some good food and some good prices.
