The more you learn what the codes really mean, the more discouraged you are.
Food listed as natural means nothing at all. It is willfully misleading the consumer. This food is conventional and most likely GMO as well. Natural has zero regulation.
You don't even want to know how they "make" commercial orange juice. It's appalling what is allowed, and nothing you should consume, if you care about ingesting synthetic chemicals.
Cage-free means hundreds are crammed in a large building with cement floors and perches, but they are not separated by cages.
Free-range has its downsides too, and might mean hundreds of chickens have access to a door to a small space outside that is just dirt, but nothing to graze upon.
Vegetarian fed hens could still include GMO feed. And I wonder why the big deal about vegetarian fed anyway? Chickens love eating snails, and that's the proper circle of life anyway if you want your garden to grow. Snails eat gardens, but chickens eat snails, and then we can eat their eggs.
Although corn is on the Clean Fifteen list, and therefore okay to buy conventional, ALL corn that is not organic is GMO corn (has to do with cross-pollination).
Pasteurized dairy is bad enough in terms of removing important health-giving qualities, but UHT milk (high heat processed) makes this milk bad for you. It doesn't offer a thing for your health. Oh, but it does seem to last a couple months in the fridge, even after opened.
Despite how regulated the one poster said organic food is, there are still plenty of problems with it. That said, it's still safer to buy organic, which will definitely be ahead of conventionally grown food. Whenever possible, buy directly from farmers (ask questions at farmers' markets - some have conventional food, and some are big corps setting up a stand without signage and allowing you to assume it's just a small organic farmer).
I can get organic beef that is grass-fed and grass-finished for $4.29/lb delivered to my home, and that includes the most expensive cuts of steak. How? I go in on half a cow with a few friends and buy direct from the farmer. Everything is packaged well. We freeze it and have tasty meat with superb texture for some months (depending how often we eat beef, of course). Before doing this, we never bought steak, because it is many times more per pound at the store. Feel free to contact this farm at the link. If you want to make healthy delicious broths, the bones are only $0.75/lb. Also, even if you aren't in Oregon, maybe they could give you a referral to a trustworthy ranch / farm where you live.
