It may not be only the preservatives, (they'll need to do more research to figure it out), but I'd be willing to bet money that they're at least partly responsible. Preservatives are designed to keep bacteria from growing. If you eat nothing but McDonald's food, they're bound to have an effect on the bacteria in your digestive system.
I'm studying microbiology in college and I have done preservative challenge tests in the lab.
And I agree about there being much healthier options out there. I call McDonald's "food" edible food-like substances.
I'd have to agree, even if its not the only cause the preservatives are certainly a factor, and yes edible food like substances seems a better description for their 'food'.
