If you are a huge fan of a certain Rockford fast food chain, an investigation may change your eating habits. 

People are very health conscious and with time never on anyone's side, fast food is usually the choice for lunch or supper. So is the food we are eating healthy?

There was an investigation done by the CBC which involved using DNA testing on chicken from various fast food restaurants. Those included Mcdonald's, Wendy's, A&W, Tim Hortons (an east coast and Canadian franchise) and two different kinds of chicken from Subway.

When you watch the commercials, they tend to say that the chicken you eat is "straight off the farm". After some testing, that is not always the case.

A researcher from a Canadian University tested the chicken and came up with some surprising results.

Here is what they found in four of the six pieces of chicken:

"   A&W Chicken Grill Deluxe averaged 89.4 per cent chicken DNA

    McDonald's Country Chicken - Grilled averaged 84.9 per cent chicken DNA

    Tim Hortons Chipotle Chicken Grilled Wrap averaged 86.5 per cent chicken DNA    

    Wendy's Grilled Chicken Sandwich averaged 88.5 per cent chicken DNA"

Since they use salt and other ingredients on the chicken, that number will be lower than 100. Then there is the other two samples of chicken.

Both the oven roasted chicken and the chicken strips had to be tested more than once because the number was lower than expected. After the second round of testing, the oven roasted chicken only tested at 53.6% and the chicken strips only tested at 42.8%. Which means that one of the chickens has less than 50% actual chicken.

So now you are wondering what is the other ingredient that fills us each day at Subway when we eat the chicken? That ingredient is Soy. It is not a bad item to eat, but too much of it could cause some effects down the road.

Here is what Subway Canada had to say about the findings:

"SUBWAY Canada cannot confirm the veracity of the results of the lab testing you had conducted. However, we are concerned by the alleged findings you cite with respect to the proportion of soy content. Our chicken strips and oven roasted chicken contain 1% or less of soy protein. We use this ingredient in these products as a means to help stabilize the texture and moisture. All of our chicken items are made from 100% white meat chicken which is marinated, oven roasted and grilled. We tested our chicken products recently for nutritional and quality attributes and found it met our food quality standards. 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."

Will this change your eating habits? I am still a fan of the food, but this could change the way food is processed. This is not the first time Subway has been called out. Back in 2015, the fast food chain said it was going to stop using antibiotics in its food.
