Let's begin our adventure to becoming health superheroes!


Part 1: Your Amazing Body and How to Protect It

Our bodies are incredible! They have many different parts that work together as a team. Let's meet a few of them and learn how to be their bodyguard.

Our Super Parts and Their Jobs

Every part of your body has a special job to do.

• Eyes: These are your body's cameras! Their main job is to see the world around you, from the bright colours of a rainbow to the words in your favourite book.
• Teeth: Chomp, chomp! Your teeth are for chewing food into small pieces so you can swallow and digest it easily.
• Spine: This is the tall tower of bones in your back. Its job is to support your body and help you stand up straight. It’s like the main pole holding up a tent!

How to Be a Bodyguard for Your Body

Protecting our body parts is super important so they can keep working well.

Caring for Your Eyes

• Don't read in places that are too dark.
• Take breaks when using a computer or tablet. Look at something far away for a few seconds.
• Never look directly at the sun!

Keeping Your Teeth Strong

• Brush your teeth at least twice a day (in the morning and before bed).
• Don't eat too many sugary sweets and drinks.
• Visit a dentist to check that your teeth are healthy.

Good Posture: Stand and Sit Tall!

Posture is the way you hold your body when you are standing or sitting. Good posture protects your spine!

• When sitting, keep your back straight and your feet flat on the floor. Imagine a string is pulling the top of your head up to the ceiling.
• When standing, stand up tall with your shoulders back. Try not to slouch like a wet noodle!

Did you know? Good posture can make you feel more confident and helps you breathe more easily!

Key Takeaway

Our body parts, like our eyes, teeth, and spine, have important jobs. We can protect them by practising good habits like taking screen breaks, brushing our teeth, and sitting up straight.


Part 2: The Four Big Secrets to Being Healthy

Scientists have found that there are four big secrets to a healthy life. If you practice them, you'll feel great!

1. Balanced Diet: Eating a variety of healthy foods.
2. Regular Exercise: Moving your body every day.
3. Adequate Sleep: Getting enough rest at night.
4. Happy Mood: Keeping your mind and feelings happy.

Key Takeaway

To be truly healthy, we need to do more than just one thing. We need to eat well, move often, sleep enough, and stay happy. It's all about balance!


Part 3: The Food Adventure - Fuelling Your Body

Don't worry if this seems tricky at first! Learning about food is a fun adventure. Let's become food experts and learn how to give our bodies the best fuel.

The Healthy Eating Food Pyramid

Imagine a pyramid! The foods at the big bottom part are the ones we should eat the most of. The foods at the small top part are the ones we should eat the least of.

• Eat Most (Bottom Layer): Grains like rice, bread, and noodles. They give us energy to run and play.
• Eat More (Next Layer): Fruits and Vegetables. They are full of vitamins that act like a shield to protect us from getting sick.
• Eat Moderately (Middle Layer): Meat, fish, eggs, beans, and milk. These are "builder" foods that help us grow and make our bones and muscles strong.
• Eat Least (Top Layer): Fats, oils, and sugar like sweets, fried food, and soft drinks. These are okay as a small treat sometimes, but not too much!

Meet the Nutrients: The Magic Inside Our Food

Nutrients are the special substances in food that our bodies need. There are six main types:

• Carbohydrates: These are the 'Go' foods. They are the main source of energy for our body. Think of them as the petrol for a car! Found in: rice, bread, potatoes.

• Proteins: These are the 'Grow' foods. They are the building blocks that help build and repair our body, like our muscles. Found in: meat, fish, eggs, tofu, beans.

• Fats: These give us a lot of energy and help keep our bodies warm. We only need a small amount of healthy fats. Found in: cooking oil, nuts, butter.

• Vitamins and Minerals: These are our body's 'Shields'. They protect us from sickness and keep our eyes, skin, and bones healthy. We need many different kinds! Found in: fruits and vegetables.

• Dietary Fibre: This is the 'Cleaner'. It helps to clean our digestive system and keeps everything moving smoothly. Found in: vegetables, fruits, whole grains.

• Water: The 'Super Helper'! Water is essential for our whole body. It helps carry the other nutrients around and keeps us cool.

Quick Review Box

Carbs = Go!
Protein = Grow!
Vitamins = Shield!
Remembering this simple trick can help you make healthy choices!

Keeping Food Safe and Yummy

It's not just about what you eat, but also how you prepare and store it!

• Handling Food: Always wash your hands with soap before you touch food. It's also a good idea to wash fruits and vegetables before eating them.

• Storing Food: Some foods, like milk and meat, need to be kept in the refrigerator to stay fresh and stop bad germs from growing. Other foods, like bread, can be stored in a cool, dry place.

Key Takeaway

A balanced diet means eating different types of food from the Healthy Eating Food Pyramid. Food contains different nutrients (like carbohydrates for energy and protein for growth) that our body needs. Always handle and store food correctly to keep it safe.


Part 4: Things to ALWAYS Say 'No' To

Part of a healthy lifestyle is knowing what is harmful to our bodies. There are some things we must always avoid to stay safe and strong.

Harmful Habits and Substances

• Smoking: Smoking tobacco is very bad for the lungs, the parts of our body that help us breathe. It can make it very difficult to breathe and causes serious diseases.

• Alcohol Abuse: This means drinking too much alcohol. It can damage important organs in our body like the liver and the brain.

• Drug Abuse and Illicit Drugs: Using harmful drugs is extremely dangerous. They can severely damage your body and your mind, and make you very sick. It is important to always say NO if anyone ever offers you drugs.

Key Takeaway

To protect our health, we must always avoid harmful substances. Saying 'no' to smoking, alcohol, and drugs is a powerful way to take care of your one and only body!
