Nutrition

We need food, water and oxygen to live. Nutrients are the substances which our body needs to live, grow, and make repairs. Nutrients also give us energy.

The main nutrients are:

1- Carbohydrates give us energy. We need energy for everything we do, such as running around, talking, thinking etc. We can nd carbohydrates in bread, potatoes, rice, fruits, cakes, and other sweet foods.

2- Proteins. Our body uses them to grow and repair itself. We can nd proteins in meat, sh, eggs, nuts, milk and beans.

3- Fats are needed by your body for energy and warmth. There are two types of fats: saturated and unsaturated. Saturated fats are in animal products, such as butter and fatty meat. Unsaturated fats are found in non-animal products such as olive oil and nuts.

4- Vitamins and minerals. Vitamins are essential for our bodies to function well. Minerals are nutrients that plants get from the soil and pass on
to you. Fruits and vegetables are good sources, but minerals and vitamins are also found in other foods. Milk gives us calcium for our bones.

5- Fibre is a type of carbohydrate found in wholemeal bread, fruits and vegetables. We cannot digest bre, so it helps the muscles of your intestines to move food ef ciently through your digestive system.

6- Water is vital for life. Most of our body is made up of water, so it is essential. We drink water, and our body also obtains water from food.

3) If we have to lunch a ham and cheese sandwich with salad, say the main composition (carbohydrates, proteins and fats) and the juices which work in the digestion.
