What's the one food you refuse to eat? Peas, tofu, liver and onions? Whatever it is, it's probably because you don't like the way it tastes, not necessarily because it contains ingredients suspected of causing cancer or because it was picked by farmers wearing Hazmat suits. Yet, there are still a lot of those foods on store shelves, and food-industry insiders, who know what goes on behind the scenes, refuse to eat them. We polled some of those insiders--people who know the business and work daily to evict pesticides, genetically modified organisms, animal cruelty, social injustice, and unhealthy foods from the food supply--to find out what they know about the dark side of "convenience" foods and what they will eat. Take note so you, too, can avoid the worst of what grocery stores have to offer.
