Food gives energy to the body. Food contains many different substances that keep the body fit and healthy.

Carbohydrates and fats give energy to the body. Carbohydrates are found in potatoes, rice, and bread. Fats are found in milk, butter, and cheese.

Proteins help the body grow and repair worn out or damaged parts. These are found in meat, eggs, milk, and grains.

Vitamins and minerals in food keep the body healthy. They are found in fresh fruits and vegetables.

Food also contains fiber. That part of the food which cannot be broken into simple substances by the body is called fiber. Fiber keeps the intestines in good working order. Vegetables, fruits, and grains have fibers.

Food has water in it. We also drink water. Water helps blood carry all the substances around the body.

Food and Health:

To stay healthy, you must eat meals that contain all the food substances in the right amounts. Eating such foods is called a "balanced diet".

While you are growing, you need proteins. You also need fresh fruits and vegetables. You should eat meals regularly and should not remain hungry for long periods of time.
