Energy and nutrients

Food and drinks provide energy and nutrients in different amounts, they have important functions in the body and people require different amounts.

 

Energy and nutrients are provided by the diet, i.e. the food and drinks that are consumed.  Nutrients, as well as fibre and water, have important functions.

 

Knowing the sources of energy and nutrients is important in following healthy eating guidelines and meeting the dietary reference values.

 

This area covers:

  • energy;
  • energy balance;
  • energy and nutrients (including fibre);
  • nutritional needs throughout life.

Activity 1 - We need food and drink to stay alive 

Ask the children the following questions to start them thinking about food and drinks.

  • What types of food and drinks do you like/dislike?
  • What meals do we usually eat during the day?
  • At what times are these meals eaten?
  • How do you feel when it is nearly lunchtime or at other times when you need some food?

Draw a person on the board and write or draw children’s responses to how they feel when they need food or a drink around the person (e.g. tummy rumbles, feel tired or grumpy, find it hard to work or concentrate). Talk to the children about why they think they might get these feelings.

 

Explain that the body needs food, and water from drinks, to keep us alive. When we have feelings of hunger and thirst, it is our body reminding us that it needs food and water.

 

Task the children to complete the When I am hungry worksheet. Ask them to draw their face when they are hungry and when they have eaten.

Activity 2 - We need food to grow, be active and maintain health.

Question the children to help them consider why we need food. 

  • Why do we need food?
  • What does food do?

Collect children’s responses in words or illustrations and steer children to consider the things our bodies do during the day, e.g. growing, learning, playing and healing.  Use the Food – a fact of life presentation to facilitate the discussion.

 

Explain to the children that we need food to grow, be active and stay healthy.

 

Ask the children to complete the How does food help my body? worksheet. Get them to draw or write about how food helps their body. Ask them to share their work with others. You could use the children’s completed sheets to create a display.

 

For younger children, you could write in the words before photocopying the sheet so they can copy underneath. 

Resources for 5-7 Years

Activity packs for 5-7 years

Take a look at our Activity packs for learners aged 5-7 years. The packs comprise food themed resources around topics such as Harvest festival, Space, Bread and Victorians.

 

Energy and nutrients for 7-11 years

Use these eight activities to run a sessions on energy and nutrients in your classroom. 

Explain to the children that food and drinks (except water) provide energy for the body so that we can grow, be active and stay healthy. Food and drink are the ‘fuel’ for the body.

 

Different types of food and drink provide different amounts of energy. Use the Energy presentation to talk to the children about the energy provided by food and drinks and how it is used.

 

Ask the children to name the unit of measurement used when taking about energy provided by food. Explain we measure energy from food in kilojoules (kJ) or kilocalories (kcal), more commonly known as ‘calories’. 

 

Show the children the Energy cards. Draw children’s attention to where the card states the energy provided by 100g of the food shown. It might be useful to demonstrate weighing out 100g for some of the food shown on the cards so the children can appreciate what 100g of different food looks like, e.g. lettuce, bread, spread.

 

Handout the Energy cards and task the children to line up from highest to lowest by amount of energy. Make sure everyone is looking at the energy in kilojoules. Question the children to see what they notice:

  • Which food has the highest amount of energy?
  • Which food has the lowest amount of energy?
  • What other food might go at the highest or lowest energy end of the line?
  • Can you make a statement about the types of food at the lowest and highest end of the line?

Summarise that fruit and vegetables are usually lower in energy and food such as oils and spreads are usually higher in energy.

Give out the Energy cards and ask the children to line up from lowest to highest in energy per 100g.  Make a note on the board of the two or three foods at each end of the line. Question the children:

  • Do we always eat 100g of a food?
  • What food do you think we would eat in amounts less than 100g? (e.g. spread)
  • What food might we eat in amounts more than 100g? (e.g. potatoes)

Explain to the children that we eat different food in different amounts – sometimes known as ‘servings’. Point out to the children that the Energy cards also show a weight range for a typical ‘serving’ of each food. These serving ranges are for children aged 7-10 years. Question the children to check they can see the information:

  • Who has a food which has a serving of less than 20g? What is the food and the serving size?
  • Who has a food which has a serving of around 80g? What is the food and the serving size?

Ask the children what they think will happen to the amount of energy provided by the food if the serving size changes.

 

Ask a few of the children (perhaps those at either end of the line) to calculate (roughly) what the energy provided by their food would be if they had a serving size rather than 100g. Ask them to move to a place in the line where they would be according to the energy provided by a serving of their food.

 

Establish that if we have a smaller or larger amount of a food or drink, the energy it provides changes (it goes down or up).

 

Divide the children into small groups and provide each group with a copy of the Serving size and energy worksheet and a set of weighing scales. Provide each group with a set of the food below. Check that each food has a label showing the energy provided by 100g.

  • Spread (tub)
  • Breakfast cereal (boxed)
  • Bread (packaged)
  • Carrots (bagged)
  • Oranges (netted)
  • Baked beans (canned)

Before the children start the task, ask them to look at the food packaging and identify where on the label they can find the energy provided by 100g.

 

Challenge the children to weigh 100g of each food to see what this looks like and then record the amount of energy provided by 100g in kilojoules. Ask the children to calculate what serving size they think they would eat and the energy this would contain. 

 

When the children have finished the task, talk through the serving sizes of each food they thought they would probably eat and how the energy provided compares with 100g of the food.

 

To conclude the session, use the Energy and serving size spreadsheet to model the effect of changing serving size on the energy provided by a food.

Recap that energy is provided by the food and drinks we consume. Ask the children why energy is needed and how it is used. Establish that we need energy to live and be active.

 

Explain that the energy we use, through being active, is also measured in kilojoules (kJ).

 

Handout the Activity and energy cards and ask the children to order the activities from the lowest to highest amount of energy they think a primary school child would use doing the activity for 15 minutes.

 

Use the Energy used factsheet to reveal the energy requirements for each activity. Did the children order the cards correctly? Summerise that some activities require more energy than other types. Can the children make a statement about the types of activities they would expect to use more energy and those they would expect to use less?

 

Provide the children with a copy of the Energy used factsheet. Task them to record what they might do during a typical day on the Activity diary worksheet and then calculate the energy that would be used doing each activity and the total energy used for the day. You could let the children work in pairs and have access to calculators for this task.

Question the children about the amount of energy different people might need.

  • Does everyone need the same amount of energy (from food and drinks)?
  • Who might need more or less?
  • Why might this be?

Give each group a copy of the Energy needs worksheet. Task the children to discuss the different people on the sheet and what energy requirements they might have. They should then note the amount of energy they think each person will need in a day. Some examples have been provided to help the children with their estimates.

 

Discuss with the children the energy amounts that have allocated to each person. Give out copies of the Energy needs factsheet so the children can check their answers and look at other people’s energy requirements. Ask them to make a note of anything they find interesting. Discuss what they have noticed. 

 

Explain that every day most of our energy is used keeping our body working, e.g. breathing, heart beating, blinking, eating.

Introduce the concept of energy balance to the children. Energy is:

  • provided from the food and drinks consumed (in);
  • used by normal body functions, such as breathing, blinking and eating, and undertaking different types of activity (out).

Over time:

  • If we consume more energy than we use, we will gain weight;
  • If we consume less energy than we use, we will lose weight;
  • If we have energy balance (consuming and using the same amount of energy), our weight will stay the same.

Discuss with the class problems with being over- and under- weight. Discuss the reasons, both in the UK and globally, as to why people may become over- or underweight.

 

Further activities

  • Task the children to collect different food packaging or labelling. Making a display of the different amounts of energy provided by foods.

Energy resources for 7-11 Years

Use the Nutrients presentation to introduce the concept that food and drinks provide nutrients, water and fibre. The presentation covers the following points.

  • Food and drinks contains different substances that are needed for health. These are nutrients, water and fibre.
  • All food and drinks provide nutrients.
  • Different types of food and drinks provide nutrients in different amounts.
  • To get the range of nutrients needed, we are all encouraged to eat a variety of food from different food groups – a healthy diet.
  • The nutrients are carbohydrate, protein, fat, vitamins and minerals.
  • Some food also provides fibre. Fibre is important as it helps to keep the gut healthy.
  • We need water to stay alive.

Use the Nutrient cards to help the children explore nutrients further. Ask the pupils to stand at the front of the room and hand out the cards. Explain the abbreviations on the cards (g = gram, mg = milligram, µg = microgram) and that these show 100g of each food. Ask a few questions about the information on the cards to check the children are clear about how to read them, e.g. How many grams of fat is in the food on your card?

 

Ask the pupils to order themselves from highest to lowest in each nutrient - carbohydrate, protein, fat, vitamins and minerals and fibre per 100g. Each time the children have ordered themselves, ask them to look at the food that is highest (and lowest) in the given nutrient or fibre and talk about what they notice. Show the presentation slides which align the nutrients and fibre with food in a food group – does this match which what they are seeing in the line regarding certain food being a main source of certain nutrients (and fibre)?

Discuss with the children that the amount of a nutrient provided by a food (or drink) depends on the serving size. Display a selection of food packaging around the room. Ensure the nutrition labels on the packaging provide the nutrients both per 100g and per serving. Here are some ideas for packaged foods to display:

  • Whole grain cereal
  • Canned potatoes
  • Loaf of bread
  • Can of tuna
  • Can of beans
  • Can of chickpeas
  • Tub of spread
  • Tub of butter
  • Bottle of oil (plastic)
  • Bag of carrots
  • Bag of lettuce
  • Packet of tomatoes

Task the children to look at the food labels to complete the worksheet Nutrients and portion size.  Before they start, explain that they will look at total fat and total carbohydrate on the labels so they can ignore the ‘of which saturate’ and ‘of which sugars’ under the fat and carbohydrate information.

When the children have finished, talk about the differences they notice between the amounts of various nutrients per 100g and per serving.

Summarise that the amount of a food eaten will affect the amount of a nutrient provided. To get the range of nutrients needed by the body, we are all encouraged to eat a variety of food from different food groups – a healthy diet.

Below is a table of the key information children should cover during this session.  

 

Food Group

Nutrient (main)

Function

Fruit and vegetables

Vitamins, e.g. Vitamin A and Vitamin C

Vitamin A is needed for night vision.

Vitamin C is needed for the maintenance of healthy skin.

 

Potatoes, bread, rice, pasta and other starchy carbohydrates

Carbohydrate

Carbohydrate is the main source of energy for the body.

 

Beans, pulses, fish, eggs, meat and other proteins

Protein

 

Minerals, e.g. Iron

 

Protein is needed for growth and repair.

 

Iron is a mineral which is needed for healthy blood.

 

Dairy and alternatives

Minerals, e.g. Calcium

Calcium is a mineral which is needed for the growth and maintenance of strong bones and teeth.

 

Oil and spreads

Fat

Fat is needed for health, but in small amounts.

 

Note: While it is appreciated that nutrients may be provided by more than one food group, at this stage of learning the information has been simplified provide a firm foundation of understanding. Only key examples have been provided.

Explain to the children that as well as having important jobs in the body, the nutrients carbohydrate, protein and fat also provide energy (which is needed by the body to grow, maintain health and be active).

 

Ask the children to rank the Nutrient cards for food providing the most/least carbohydrate, protein and fat. Compare the amount of energy provided by different nutrients.

  • Is there an association? (For example, spread provides 81.6g fat and 3039kJ energy per 100g, compared with a tomato that provides 0.3g fat and 73kJ per 100g.)

The learning is that while carbohydrate, protein and fat all provide energy, fat provides the most energy per gram (compared to carbohydrate and protein). Inform the children that the main source of energy should be from carbohydrate.

 

Further activities

  • Get children to write a healthy eating report for the school newsletter or website. They could also write recipes or produce a storyboard about healthy eating in a day.
  • Challenge older children to produce a presentation about the nutrients provided by food.
  • You may wish to provide extension activities for some children or show the energy and nutrients provided by a range of food, recipe, menu or diet. Explore Food is a free nutritional analysis tool that enables you to undertake this type of activity. 

Nutrients resources for 7-11 Years

Energy and nutrients for 11-14 years

The lessons and resources below cover:

  • energy;
  • energy balance;
  • energy and nutrients (including fibre);
  • nutritional needs throughout life.

The resources and pupil activities below can be used to support this understanding. 

Energy

An important aspect of understanding and applying the principles of nutrition and health is energy and energy balance. To introduce the topic to pupils show the Energy presentation. Use the Energy worksheet and either show on a screen or provide printed copies. Challenge the pupils complete the questions either as a class or working individually.

 

The DRV fact sheet can be used as a teacher resource to provide more detail and data on dietary reference values.

 

Provide a range of food packaging and/or products for the pupils to investigate; what information is given to the consumer? How does it help consumers make choices? What does the red, amber, green coding mean?

 

Use the Kahoot - energy requirements or a printed version of Kahoot - energy requirements Q&A test the pupils understanding of energy requirements.

Energy resources for 11-14 years

Energy balance

To introduce the concept of energy balance, show the Energy balance presentation. Task the pupils to produce an information leaflet, blog or article for your school website to encourage the whole school community to consider their energy balance and physical activity.

 

Challenge the pupils to consider the impact of energy in versus energy out using the Energy in, energy out presentation. Use the Energy expenditure in physical activity fact sheet to support this activity.

Energy balance resources

Energy and nutrients in the diet

The resources and pupil activities below can be used to support teaching and learning about energy and nutrients in the diet.

 

Introduce pupils to macro and micronutrients using the Nutrients presentation. Task the pupils to complete the  Nutrients note sheet to help consolidate their learning.

 

Help the pupils link the Eatwell Guide food groups and nutrients by using the Where do nutrients come from? worksheet. This could be extended by asking the pupils to identify the food groups and nutrients in composite dishes, e.g. lamb Rogan josh with rice, vegetable lasagne and salad.

 

Provide the pupils with a set of statements found in the Nutrient matching cards and task them to select the correct match.

 

Complete the Kahoot - nutrients quiz and Kahoot nutrients Q&A to review and check understanding.

 

Compare a variety of similar food that has been modified, for instance to reduce the fat content, e.g. potato crisps that have been baked rather than fried. Discuss the claims that are made on the packaging and/or advertising. Review the food labels and compare the nutritional value. Ask the pupils what they notice about the ingredients and methods of cooking that have been used to make the products.

 

If time allows challenge the pupils to prepare a dish that provides a particular nutrient. For example they could produce a meat or vegetarian alternative dish that provides a source of iron. Ask the pupils to prepare a short explanation about the ingredients they have chosen and justify their choice. Use a nutritional analysis programme, such as Explore food, to create a nutritional analysis of their dish.

 

Use a nutritional analysis programme, such as Explore food, to investigate the energy and nutrient values of different food commodities. Complete the Energy and nutrients provided by different food worksheet and compare the food that have been analysed. Discuss with the pupils how this knowledge might influence ingredient selection.

 

Task the pupils to complete the Nutrient Matching activity. Print and cut out the two sets of cards (they could be laminated for future use) along with a set of Eatwell Guide food cards. Organise the pupils into small groups and ask them to match the nutrient, function and food source(s).

 

The nutrients provided by a food or dish depend on the serving size. Serving sizes depend on individual needs, for example age or lifestyle, meal occasion and type, and should always be considered when planning recipes and meals. Task the pupils to analyse two recipes using the Serving size worksheet and note down the energy (kilocalories/kilojoules) provided per person for each serving size.

 

To enhance the pupils knowledge of fibre in the diet show them the Dietary fibre presentation and then ask the pupils to complete the Dietary fibre worksheet.

 

Complete the Fibre line up activity. Organise the class into groups. Distribute the Fibre food cards. Explain to the pupils that they should discuss the order in which they think the foods should be placed to show the least to the most fibre. Compare each group and give the correct Fibre line up answers. Discuss why some foods are higher in fibre than others.

 

Display a range of different foods (or use the Fibre line up activity images). Ask the pupils to identify the food that they think provides dietary fibre.

 

Challenge the pupils to use a nutritional analysis programme such as Explore food to calculate and compare the fibre provided by a range of food; for example white and brown rice, white and granary bread, cornflakes and porridge oats. Ask the pupils to present this information on a series of graphs.

 

Provide the pupils with the Change for health worksheet and ask them to review a lasagne recipe and indicate the changes they would make to reduce total fat and increase fibre content. It time allows, challenge the pupils to make the standard and modified recipe and then conduct a sensory evaluation and nutritional analysis of the dishes.

 

To develop independent research and enable pupils to make their own choices around cooking for health, complete the Make it with mince challenge – higher fibre dishes.

 

To consolidate their learning challenge the pupils to complete the Dietary fibre Kahoot quiz and Dietary fibre Kahoot quiz answers.

Energy and nutrients in the diet resources

Nutritional needs throughout life

The resources and pupil activities below can be used to support teaching and learning about nutritional needs through life. 

 

Ask the pupils to identify the different life stages and discuss why people might have different nutritional needs. Use the Nutritional needs through life presentation to introduce the specific needs at different life stages. Task the pupils to complete the Diet through life worksheet.

 

Ask the pupils to apply their learning about nutrients and their functions to plan, justify and make a suitable lunchtime meal for one of the identified life stages.

 

Task the pupils to complete the Nutritional Requirements chart which shows the nutrients required at different life stages, their sources and function.

 

Provide the pupils with Nutritional needs (energy) through life worksheet. The pupils can work in pairs to complete the worksheet identifying the key information about energy requirements for each group.

 

Plan a practical challenge for the pupils; identify a suitable age/stage for the pupils. Discuss the main nutrients that should be included in the diet. Prepare a savoury dish that is suitable for the selected age/stage and identify the main nutrients provided by the dish.

 

Divide the class into 6 groups and assign each group an age stage: pregnancy, infancy, childhood, adolescence, adult and older adults. Ask the pupils to use the Nutritional needs through life foundation presentation to create a summary of the nutritional needs and dietary considerations for their assigned age stage. Present the pupils with the challenge of planning a two course menu suitable for the age stage. The two course meal must consist of simple dishes which can be prepared within a 60 minute time frame. The group assigned to infancy could be asked to plan the menu for a breastfeeding mother rather than the infant. Invite each group to present their findings about the life stage they were assigned and introduce the draft menu plan. Allow time for the pupils to provide comments on the menu plan. The class should take notes from each group’s presentation to create a summary of the dietary needs for each life stage.

 

Discuss why it is important to have a nutritious breakfast before going to school or college. What food can be served? Challenge the pupils to make a range of breakfast dishes and invite parents and carers in to school to share the meal. Alternatively, work with the school caterer and organise for the pupils to plan and create a range of breakfast dishes to be served in the school cafeteria.

 

Challenge the pupils to complete the Nutritional needs through life Kahoot quiz. Use the Nutritional needs through life Kahoot answers to check their knowledge.

 

Organise the pupils to work in small groups or individually. Explain to the pupils that they are to create a mind map or set of flash cards to summarise what happens at each life stage. Include the important nutrients and give advice about the importance of healthy food choices.

 

Show the pupils the Dietary Reference Values presentation to explain nutritional requirements and Dietary Reference Values. Challenge the pupils to complete the DRVs Kahoot quiz or DRVs Kahoot Q&A to consolidate their learning.

 

The DRV fact sheet can be used as a teacher resource to provide more detail and data on dietary reference values.

 

Use the information and data from the presentation to plan meals for a day that will meet the Estimated Average Requirement (EAR) for energy for someone in your age group.

Nutritional needs through life resources (11-14 years)

Energy and nutrients for 14-16 years

It is important that students understand the functions, main sources and dietary reference values of energy and nutrients, and the consequences of consuming too much or too little. They should also be able to apply their knowledge of energy and nutrients to food choices and healthy eating.

 

This area includes:

  • Energy
  • Nutrients
  • Macronutrients
  • Micronutrients
  • Fibre
  • Water
  • Alcohol
