Pop quiz! Which has been reported to contain the most sodium: a serving of beef, a serving of baked all-natural chicken, a large McDonald’s french fries, or a serving of salted pretzels? The answer? Chicken. The poultry industry commonly injects chicken carcasses with salt water to artificially inflate their weight, yet they can still be labelled “100 percent natural.” Consumer Reports found that some supermarket chickens were pumped so full of salt that they registered a whopping 840 mg of sodium per serving—that could mean more than a full day’s worth of sodium in just one chicken breast.
