LOOK AFTER YOURSELF (UNIT 2 NS)

A healthy diet is a balanced diet. 

Fruit and vegetables are full of vitamins, minerals and fibre. Fruit has quite a lot of sugar ,so try to eat more vegetables than fruit. Some examples include: broccoli, onion, pepper, carrots, spinach, apples, bananas, cherries, oranges, and many more!

Dairy products are made from milk .They are rich in calcium, which keeps our bones and teeth healthy. Cheese, yoghurt, and milk are dairy products.

Proteins and Iron help us build muscle and make us strong. Meat, fish, beans and eggs contain proteins and iron.

Carbohydrates give us lots of energy. Fibre is good for our digestion. Some examples include: bread, pasta, rice, and other grains. 

Fats help our brain and nervous system .Some fats are better for us than others. Good fats include olive oil, salmon, nuts and avocados.

We have three main meals every day: breakfast, lunch and dinner. We also have two snacks, in the morning and in the afternoon. 

DON'T FORGET...

Water is very important. About 75% of our bodies is water. We should drink 1.5 litres of water every day (that's 6 glasses)!

Circulatory system

The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body's tissues. With each heartbeat, blood is sent throughout our bodies, carrying oxygen and nutrients to all of our cells.

Human Digestive System 

Our body needs food to provide it with energy, vitamins, and minerals. However, in order use food, we must first break it down into substances that the various organs and cells in our body can use. This is the job of our digestive system. The digestive system acts in stages to digest our food.

Respiratory system

Humans breathe through something called the respiratory system. This system is made up primarily of our lungs and windpipe. 

Our body is a very complex system. One of the main things it needs is energy. We get the oxygen to our cells with the respiratory system and by breathing.
