请以“A healthy diet”为题,写一篇英语文章.要求：60词左右,短文中应该讲到健康饮食的重要性；一日三餐所吃

A healthy diet can provide the necessary energy for us,so to keep us fit.But it is not very easy to make your diet always healthy.In my view,people need to spend time on thinking about how to eat every meal.One of the principles is that we should not eat too much or too less.The other is that the junk food should be thrown away.For example,vegetable,fruits which contain high vitamin,and low fat meat,such as chicken ,fish are good choicies.Food like french fries,hamburgur,and other high-fat and low protein food should be avoided.People can look up the calorie of each kind of food online and arrange their meals in a very healthy way.
