McDonald's is unhealthy. However, if you eat other healthy food and exercise regularly, then you can still eat McDonald's. I honestly think McDonald's food tastes good if you only eat it once in a while.
Well, of course McDonald's is unhealthy. But, they are good. Just don't eat them every time you go out to eat. Try Subway. (Club, everything on it, black olives, pickles. Oh, it makes my mouth water just thinking about it.)
If you think about it enough. The food could go through the government. They could be causing the obesity epidemic in the U.S. Don't know why, yet.
I suppose making the majority of your citizens fat obese balls of grease with massively increased chances of heart, liver, kidney failure that hinders your economy and pulls down your medical system is a good enough idea that the government wants to adopt it!
Conclusion: Americans are willing to take anything as a conspiracy just as much as they're willing to eat anything dipped in butter and deep fried.
