Junk food has for a long time been eaten by people.  It is considered easy to get and cheap to buy.  Lots of commerciasl every day are broadcast  on the radio and TV. 
I strongly believe that advertizing junk  and unhealthy food should be prohibited.  Doctors say that junk food leads to obesity and serious diseases.  Children like it because it looks nice and smells nice.  But they are not aware of the danger. 
Some people may think that such a ban on junk food advertisement is a  violation of rights.  It also poses danger to freedom of speech and mass media, they may think. 
But I consider that our nation's health is more important.  So we must do all we can to teach people to choose healthy food for themselves and their children. Results of scientific research in this field should be made public.  So the people will  finally make the right choice!
