What is Food?
For a Class 4 student, the definition of food can be very simple. Food is anything that we eat and drink to get the energy and nutrients our body needs to live, grow, and stay healthy. Think of food as the fuel for your body, just like petrol is fuel for a car. Without it, you wouldn't have the energy to run, jump, play, or even think in class.
Where Does Our Food Come From?
Most of the food we eat comes from two main sources: plants and animals.
- Food from Plants: We eat many different parts of plants.
- Roots: Like carrots and potatoes.
- Stems: Such as celery.
- Leaves: Including spinach and lettuce.
- Fruits: Apples, mangoes, and oranges.
- Seeds: Like rice, wheat, and pulses.
- Food from Animals: Animals provide us with a variety of food products.
- Milk: From cows, goats, and buffaloes, which we can also make into cheese and yogurt.
- Eggs: From birds like chickens.
- Meat: Such as chicken and fish.
The Main Nutrients in Our Food
Food is made up of different important parts called nutrients. A balanced diet includes all these nutrients in the right amounts to keep your body working well.
- Carbohydrates: These are the body's main source of energy. They are often called "energy-giving foods" and are found in things like bread, rice, potatoes, and sugar.
- Proteins: These are the "body-building foods." They help you grow taller, build strong muscles, and repair any damaged parts of your body. Good sources are milk, eggs, pulses, and meat.
- Fats: Fats also give us energy, even more than carbohydrates. They keep our bodies warm and help to cushion our organs. You can find fats in butter, oil, and nuts.
- Vitamins and Minerals: These are like special helpers that keep you fit and healthy. They are often called "protective foods" because they protect you from getting sick. You get them from fruits and vegetables.
- Water and Roughage: Water is important for digestion and helps move nutrients around your body. Roughage, or fiber, helps clean out your digestive system and remove waste.
The Journey of Food: Digestion
After you eat food, your body breaks it down into tiny pieces in a process called digestion. This happens inside your digestive system. First, you chew food with your teeth, then it travels down a tube called the esophagus to your stomach. Your stomach mixes the food with special juices. Next, it goes into your intestines, where the nutrients are absorbed into your blood and carried to all parts of your body. Finally, any leftover waste is removed from your body.
Healthy vs. Unhealthy Food
It's important to know the difference between healthy and unhealthy food so you can make smart choices. Healthy food gives your body the nutrients it needs, while unhealthy food can make you feel tired or sick if you eat too much.
| Feature | Healthy Food | Unhealthy Food (Junk Food) |
|---|---|---|
| Nutritional Value | High in vitamins, minerals, protein, and fiber. | Low in essential nutrients; often called "empty calories". |
| Energy | Provides steady, long-lasting energy. | Gives a quick burst of energy, followed by a "crash". |
| Ingredients | Mostly natural, fresh ingredients like fruits, vegetables, and whole grains. | Often highly processed with lots of added sugar, salt, and unhealthy fats. |
| Impact on Health | Supports growth, strengthens bones, and boosts immunity. | Can lead to weight gain, makes you feel sluggish, and can cause health problems later on. |
| Examples | Apples, carrots, whole-grain bread, milk, and chicken. | Chips, candy, sugary drinks, and too many cakes. |
How to Choose Healthy Food
- Eat the Rainbow: Try to eat fruits and vegetables of different colors every day to get a variety of vitamins.
- Look for Wholegrains: Choose whole-wheat bread and brown rice instead of white bread and rice.
- Drink Plenty of Water: Water is the best drink for your body.
- Limit Treats: It's okay to have junk food once in a while, but it shouldn't be an everyday thing.

Conclusion
For a Class 4 student, the definition of food is simple: it's what we eat and drink to get energy and nutrients. Understanding the main nutrients—carbohydrates, proteins, fats, vitamins, and minerals—and where our food comes from is the first step toward making healthy choices. By choosing healthy foods most of the time and limiting unhealthy snacks to special occasions, you can give your body the best fuel to grow strong, stay healthy, and have lots of energy for all your activities.
