Feb. 28, 2017 -- DNA tests of grilled chicken sandwiches from 5 major fast food chains revealed that chicken accounts for half or less of the ingredients in some of them.
The CBC consumer affairs show Marketplace asked scientists to conduct DNA tests of the products. They found that the average chicken DNA content was: 84.9 percent in A&W Chicken Grill Deluxe; 84.9 percent in McDonald's Country Chicken; 86.5 percent in Tim Hortons Chipotle Chicken Grilled Wrap; 88.5 percent in Wendy's Grilled Chicken Sandwich; 53.6 percent in Subway's oven roasted chicken; and 42.8 percent in Subway's chicken strips.
The majority of the remaining DNA in the Subway chicken products was soy.
In a statement, Subway said it disagrees with the test results, CBC reported.
"Our recipe calls for one per cent or less of soy protein in our chicken products," according to the statement."We will look into this again with our supplier to ensure that the chicken is meeting the high standard we set for all of our menu items and ingredients."
The chicken products included in the testing had a combined total of about 50 ingredients, and each one had an average of 16 ingredients. Many of those ingredients are variants on salt or sugar, according to nutritionist and registered dietitian Christy Brissette.
"People think they're doing themselves a favor and making themselves a healthy choice," when selecting these chicken sandwiches, she told CBC. "But from a sodium perspective you might as well eat a big portion of poutine."
