Does McDonalds sell 'junk' food?

The CEO (Chief Executive Officer - the top person/leader at McDonalds) claims that they do not sell 'junk food.'  He claims that all of the ingredients of the food at McDonalds are 'real' ingredients. 

What do you think? To be honest with you, I stopped eating at McDonalds a long time ago.  I am not sure they care about my health.

junk food - junk means garbage. Junk food would be food that does not provide nutrition or food that can be used effectively by the body.  'Waste' food might also be a term for 'junk' food.

AIDs is a kind of epidemic in Africa.

This sentence in the article is written in REALLY bad English.  It doesn't make any sense:

"My medical and public health colleagues the world over have repeatedly acknowledged the science I think McDonald’s-style fast food and the fast food practices to the decline in children’s health and McDonald’s has yet to make substitute changes," the doctor, Andrew Bremer, said to Thompson. 

I think the sentence should be:  My medical and public health colleagues (co-workers) the world over have repeatedly (over and over again) acknowledged the scientific fact that McDonalds harms children.  I think McDonalds style fast food and the fast food practices are leading to a decline (decrease) in children's health and McDonald's doesn't care and isn't changing anything.
