According to my doctor, eating this kind of food is like poisoning yourself. Not much in the way of nutrients is left after the food have been processed then frozen for a few years.
One of the guys who work for me worked for Burger King for years as a manager at one of their facilities, any idea what kind of perservatives they put in that garbage they call food? America has one of the worst diets in the entire world, this is why more than half of us are obese.
I used to eat this junk myself, when I came off it and started eating real human food, like mediteranian and other Asian ethnic cuisine, I lost a ton of weight, I used to have skin issues, it all went away.
Do yourself a favor and eat right, in my opinion McDonalds and Burger King food is not fit for dogs let alone humans.
