The best solution is to control all the ingredients in your own kitchen. Relying on labeling to protect your health is insufficient. If you select your produce, you can prefer Jim Bob's local farm over the Monsanto option. You can sidestep entire categories of health risk. I'll sometimes buy a full hand basket worth of one thing like onions or limes depending on availability and quality.
There are still some shelf stable goods that you can buy without getting screwed. But it's exceedingly rare now. Peanut butter is a good example. 99% the inventory is JIF with palm oil and added sugar in a plastic container, but on the very top (or bottom) shelf you can often find a glass jar that contains only peanuts and salt. It took me a month to get used to peanut butter like this. The exercise of stirring it almost ruined it for me. I can't imagine going back to the other stuff now. I tried JIF again recently and it tastes like a product you'd buy from Home Depot to do a drywall job.
