Key Fact 4: A variety of food is needed in the diet because different foods contain the different substances that are needed for health. These are nutrients, water and fibre.
This section provides you with detailed teaching plans for Key Fact 4, including links to all the downloadable resources.
a) To understand that all food and drink provide nutrients.
Use the Nutrients PowerPoint 153 to introduce this Key Fact, learning objectives a-g.
b) To understand that energy is provided by the nutrients carbohydrate, fat and protein.
Ask the children to rank the Nutrient Cards 153 for foods providing the most/least protein, fat and carbohydrate.
Compare the amount of energy provided by different nutrients using the Nutrient Cards 153.
- Is there an association? (For example, margarine provides 81.6g fat and 3039kJ energy per 100g, compared with a tomato that provides 0.3g fat and 73kJ per 100g.)
c) To understand that other nutrients include vitamins and minerals, which are needed to keep the body healthy.
Use the Nutrient Cards 153 to identify those foods that provide:
* vitamin C.
- Are there any groups of foods that supply similar nutrients?
- Which foods provide the most/least?
d) To understand that some foods also provide fibre. This is not digested by the body.
Use the Nutrient Cards 153 to identify those foods that provide fibre.
- Which provide the most fibre?
- Which provide the least?
e) To recognise that the amount of energy and nutrients provided by food depends on the portion eaten.
Ask the children to compare the energy and nutrients provided by foods per 100g and per portion size.
- What do they notice?
- Does portion size affect the amount of energy and nutrients provided?
Use the Nutrient Portions Worksheet (Excel) 164 to model the effect of changing portion size on the nutrients provided.
f) To understand the functions of different nutrients.
Introduce the functions of the different nutrients. Ask the children to design a poster to show the functions of the nutrients. You may wish to use the Nutrients PowerPoint 153.
Organise a cooking session, which highlights different nutrients. For example, the children could make:
- a range of sandwiches, using different breads and fillings, e.g. ham, egg, fish, beef, hummus;
- different fruit smoothies, e.g. strawberry, banana, milk and yogurt;
- salads for a party, e.g. potato, rice or pasta;
- a fish dish, e.g. mackerel pate, smoked haddock samosas.
Recipes for a sandwich wrap, smoothie, cous cous salad, mackerel pate and smoked haddock samosas are available to download at the bottom of this page. You can find more great recipes on the Cooking module.
g) To recognise the nutrients provided by each section of the Eatwell Guide.
Review The Eatwell Guide. Identify the main nutrients provided by each food group. You may wish to use the Nutrients PowerPoint 153.
Use the Nutrient Cards 153 to identify which foods belong to each group.
Ask the children to complete the Eatwell Guide and nutrients Worksheet 165 to test their understanding.
Recap with children
All foods provide nutrients.
Energy is provided by the nutrients carbohydrate, fat and protein. Other nutrients include vitamins and minerals.
The amount of energy and nutrients provided by food depends on its size, known as a portion.
Different nutrients have different functions in the body to keep us healthy.
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.
Get older children to produce a PowerPoint 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 foods, recipe, menu or diet. Explore Food is a free nutritional analysis tool that enables you to undertake this type of activity. Click here to view.
