Nowadays,fastfood becomes a part of people's life.
When everyone is busy working,fastfood is the first choice,for it's quite convenient and cheap.People can eat it in the car,or on the road or take it to home.It saves much time.So it's popular with modern people.
However,there are also disadvantages of the fast food.First,fast food is often rich in fat.It can make people fat.Second,fast food is not good for people's health.It often lacks of useful things which is good for keeping health.Besides,fast food may cause cancer.So it's very dangerous to eat fast food.
In my opinion,we don't eat too much fast food.We should eat more vegetables and friuts.
