@never give up,
Actually there is no such thing as a fast food culture. Everyone chooses his way of life, whether he wants to be healthy, eat good food, perform exercises, or repeating the actions of someone. The fact that fast food is commercialized everywhere doesn't mean you have to eat it. Globalization is another thing. Globalization is good to some extent if handled properly.
There is no or very little relationship with globalization and fast food. Food can be properly chosen. The commercials do all the bad stuff.
