The Key to Your Health
A car needs gas to run and your body also needs food to work for you. Eating the right kind of food is very important. It can help your body grow strong to take care of what you eat.
There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all these food together, you will be given enough energy during the day.
It is easy to get into bad eatinghabits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to. But you will find yourself tired in these days and you can not think quickly.
Watching what you eat will help your body remain healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.
