Summative Assessment “Sport, Health and Exercise”

Task 1. Read the text.
Matter and Energy: The foods we need to keep our bodies in tip-top shape!
There are many foods that people can eat. They can eat plants, like spinach or corn. Or, they can eat other animals. Chicken and beef come from animals. Some food choices are good for you. Others are not very healthy.
Eat Healthy, Get An Energy Boost!
Food gives your body energy. Say you are tired from running and playing. You can eat something healthy. It will give you an energy boost.
The energy in food is measured in calories. These are like invisible bits of energy. Your body burns them to make energy. Then you will feel like going out to play again!
Everybody needs a different number of calories. It is important to eat the right amount. If you do not eat enough, you may feel tired and sick. But you do not want to eat too many, either.
Some people are very active. They move around all the time. Sports stars are one example. These people need more calories.
Other people sit down all day. They work at a table or desk. They may be office workers, for example. These workers do not need as many calories.
Nutrients Help The Body Do Its Job
Foods gives us nutrients. Nutrients help the body do its job. You cannot see nutrients. Yet you cannot live without them.
Protein is one nutrient. It helps the body grow. You can get it by eating animals like meat or fish. You can also get it from many plants. Beans and nuts have lots of protein.
Carbohydrates are another nutrient. They give us a lot of energy. You can get them by eating starches. Rice and bread are two examples.
People also need minerals. Calcium is one example. It keeps your bones and teeth strong. Calcium is found in milk and cheese. You can also get it from leafy greens like spinach.
You have probably heard of vitamins. There are many different vitamins. They do many big jobs in our bodies. Vitamin C is one. It keeps your gums healthy. Vitamin D is another. It gives you strong bones and teeth.
It is important to eat well. To do this, you just have to follow a few simple rules. Scientists came up with the rules. They studied what foods make healthy bodies. The rules are: Eat lots of vegetables and fruits. Stay away from too much fat. Skip sweets and salty snacks, too. These treats taste good, but they are not good for you.
