Health is very important to everyone and we all want to keep healthy. But in a world full of junk food(垃圾食品)，it is not very easy to do so. Now let me tell you some useful ways to keep healthy.
First, we should eat right kinds of food. As we all know, eating lots of fruit and vegetables is good for our health. because they are rich in fiber(纤维素)and low in fat(脂肪). A cup of milk a day can help make us healthy too. And we shouldn't eat too much meat or candy, because too much meat may make us fat and too many candies may be bad for our teeth. And don't drink too much coffee.
Second, we should eat in a right way. We can't eat too little or too much. That can make us sick. And we must have meals three times every day on time too.
It's necessary(必要的)for us to have right food and healthy eating habits.
