In the last years, this kind of food has become very important in the society through big fast food restaurants, like McDonald and Burger King, which are the most famous.

In general, the importance of fast food is because a lot of people haven´t got time to cook in their regular lives, but some studies made by several universities show that these foods have become the favorite for worldwide population although sometimes these foods are making to increase the number of illnesses year by year.

Young people prefer the fast food before food made by their parents and they are the main buyers of this kind of food, I think that people should eat healthier food and be aware of the risks that its excessive consumition involves because, day by day, children's lives are changing, and it could produce some physical changes in their bodies or their own mouths, like in their teeth.
