      Lesson details

      Learning outcome

      I can explain why the amount of food humans eat is important.

      Key learning points

      1. A dietician is a scientist who studies food and advises people on their food and nutrition choices.
      2. Eating too much, or not enough, of certain types of food can be harmful to our health.
      3. Information about amounts of food can be found by using secondary sources of information.
      4. The Eatwell plate is a guide based on how much you should eat from each food group.

      Keywords

      • Dietician - A dietician is a person who scientifically studies and gives advice about food and eating.

      • Nutrition - Nutrition is what you take into your body as food and the way that it influences your health.

      • Amount - An amount is a quantity of something.

      • Secondary sources - Secondary sources are texts, images or objects created using information gathered by others.

      Common misconception

      Pupils may think that a ‘balanced’ diet should include equal-sized proportions of the different food groups (rather than appropriate amounts of each food group).

      Explanation that humans need to eat different amounts of foods and that the Eatwell plate shows us the amounts of each food that we should eat.

      Teacher tip

      Visit the NHS website for lots more information about the Eatwell plate.

      Equipment

      You may choose to gather a selection of real food for pupils to place onto a larger scale Eatwell plate.
