Key Stage 1
Meaning
Having a balanced diet means eating the right amounts of different food.
About a Balanced Diet
- We need a balanced diet to stay healthy. Food allows us to move, grow, repair injuries and stay alive. If we do not eat certain foods this might make us tired trying to move, might stop us growing, might make injuries very slow to heal or make us so ill we could die.
- In a balanced diet we need to make sure we get enough:
Protein
Meat provides lots of protein for a balanced diet. | You can help keep your diet balanced by eating lots of different beans. |
Nuts are the seeds of trees and are part of a balanced diet. | There are many different kinds of peas that can help make sure you have a balanced diet. |
Vitamins
Fruit are very sweet and 2 - 5 portions of them everyday help make a balanced diet. | You should eat 3 to 5 portions of vegetables everyday to get the vitamins you need in a balanced diet. | Breakfast cereal has added vitamins in them to help make a balanced diet because some people are too fussy to eat enough vegetables. |
Energy
Bread makes part of a balanced diet because it has a lot of stored energy we can use. | A balanced diet might contain pasta for energy. |
Potatoes are an excellent source of energy in a balanced diet. | Rice is a very important part of many people's balanced diet. |
Key Stage 2
Meaning
Having a balanced diet means eating different foods to make sure an animal gets enough protein, vitamins and energy.
About Balanced Diets
- Different animals need different diets, but they all need the right balance of different nutrients.
- If a diet is not balanced it can cause an animal to become ill, or not to grow properly.
- 100 years ago humans were shorter because most people didn't have a balanced diet.
Diets in Different Animals
A crocodile is a carnivore. To have a balanced diet it only needs to eat meat. | A cow is a herbivore. To have a balanced diet it needs to eat grass and grains like corn. | A hedgehog is an omnivore. To have a balanced diet a hedgehog eats insects, snails, mushrooms, grass roots and berries. |
Diet and Health
Starvation | Obesity | Scurvy | Kwashiorkor |
Not enough food, especially foods with a lot of energy, causes you to become too thin. | Too much food, especially foods with a lot of energy, causes you to gain weight and increases the risk of heart attack. | Not enough Vitamin C causes your wounds to stop healing, sores to appear on the tongue and skin and teeth to fall out. | Not enough protein causes your organs to swell. |
Key Stage 3
Meaning
Having a balanced diet means eating a variety of food to make sure you get the right amount of; carbohydrates, proteins, fats, vitamins, minerals and fibre.
About a Balanced Diet
- We need a balanced diet to stay healthy.
- Carbohydrates and fats provides us with energy for respiration.
- Proteins, vitamins and minerals in food are used for growth and repair.
- Fats and minerals help keep our nervous system healthy.
In a balanced diet we need to make sure we get enough:
- Carbohydrates - To provide energy for respiration.
- Proteins - To provide material for growth and repair.
- Fats and Oils - For our nervous system to function.
- Vitamins - For growth and repair.
- Minerals - Four growth, repair and our nervous system to function.
- Fibre - To aid digestion.
- Water - To aid digestion and keep us hydrated.
Carbohydrates
- Carbohydrates can be split into two groups. Complex Carbohydrates like starch which are very important in our diet and Simple Carbohydrates called sugars that can be harmful if we eat to much of them.
Bread makes part of a balanced diet because it has a lot of stored energy we can use. | A balanced diet might contain pasta for energy. | Potatoes are an excellent source of energy in a balanced diet. | Rice is a very important part of many people's balanced diet. |
Fruit has lots of sugar but is healthy because it also has vitamins and fibre inside. | Yoghurt has a lot of sugar but there are also some health parts like a mineral called Calcium. | Sweets are full of sugar with nothing healthy in them. | Energy drinks have nothing healthy in them and are packed with sugar. |
Protein
Meat provides lots of protein for a balanced diet. | You can help keep your diet balanced by eating lots of different beans. | Nuts are the seeds of trees and are part of a balanced diet. | There are many different kinds of peas that can help make sure you have a balanced diet. |
Fats and Oils

- If we eat too much fat and oil then we can become obese.
Meat contains useful fat for our diets, but too much can lead to heart disease. | Fish is a very healthy source of oils in our diet. | Nuts are a healthy source of oils. | Butter is full of fat and we shouldn't eat too much. Butter is found in cakes and cookies. | Cooking oil is used to fry our food causing it to have a lot of oil inside it. A small amount is healthy but too much is bad for us. |
Vitamins
Oranges, lemons and limes have a lot of vitamin C in them. | Different fruit have different vitamins so you should eat a variety of them for a balanced diet. | Different vegetables have different vitamins so you should eat a variety of them for a balanced diet. | Fish has a lot of vitamin D inside. |
Minerals
Red meat contains lots of Iron. | Yoghurt, milk and cream are a good source of calcium. | Fruit have lots of different minerals inside. | Vegetables have lots of different minerals. |
Fibre
Fruit has a lot of fibre in the skin of the fruit. | There is a lot of fibre in vegetables. | Beans are an excellent source of fibre. | Peas are one of the best vegetables to get fibre. |

Starvation | Obesity | Scurvy | Kwashiorkor |
Not enough food, especially foods with a lot of energy, causes you to become too thin. | Too much food, especially foods with a lot of energy, causes you to gain weight and increases the risk of heart attack. | Not enough Vitamin C causes your wounds to stop healing, sores to appear on the tongue and skin and teeth to fall out. | Not enough protein causes your organs to swell. |
Energy
- We get energy from our food. Carbohydrates, lipids and proteins are all stores of chemical potential energy.
The amount of energy in each nutrient per gram. |
- We must get the amount of energy we take in and the amount of energy we use the same so that we can keep healthy.
- Different activities use different amounts of energy.
The amount of energy in each nutrient per gram. |
- If we take in too little energy we feel tired (finding it hard to think), get fatigued (finding it hard to move), and feel cold (finding it hard to keep our body temperature at 37°C). However if we take in too much energy our body stores energy in fatty tissue.
- The average adult male needs to eat around 10,000kJ per day and the average adult female needs to eat around 8,000kJ per day. The amount of food and type of food determines how much energy is actually consumed.
