Subway's oven-roasted chicken may not be what you think it is
Researchers in Canada tested the DNA in multiple products from the fast-food chains and found that Subway's oven-roasted chicken is only 53.6% chicken and the sweet onion chicken teriyaki strips are only 42.8% chicken, the Canadian Broadcasting Corporation reports.
Most of the remaining DNA in the Subway items belongs to soy, according to test, which was conducted by DNA researcher Matt Harnden at Trent University's Wildlife Forensic DNA Laboratory.
In a statement to the CBC, Subway said that its recipe "calls for 1% or less of soy protein in our chicken products." The company said it will "look into this" with its supplier to make sure the chicken is meeting its standards.
The researchers also found that Wendy's grilled chicken sandwich contains 88.5% chicken DNA and McDonald's grilled chicken sandwich contains 84.9% chicken DNA.
The remaining ingredients in the sandwiches are seasonings like honey and onion powder, as well as industrial ingredients that are safe for human consumption, according to the CBC.
Wendy's and McDonald's responded to the report in statements to CBS Los Angeles:
