Lesson 5

To recognise the impact of diet, exercise, drugs and lifestyle on the way bodies function

What impact could each of the foods below have on the on the human body? (pros and cons)Think about nutrition - sugars, vitamins

Look at the nutrition chart below Do any of the sugar or fat contents surprise you? Take a look under the yellow box for more information

Look at these four food diaries. Which do you think are healthy, which are fine, and which are not?Take a peek under the yellow boxes - sometimes we can be eating foods that are not as healthy for us as we think!

What are processed foods?

A processed food is any food that has been altered in some way during preparation. Not all processed foods are unhealthy but some processed foods may contain high levels of salt, sugar and fat.

Collect a few cans and packets from your kitchen cupboards and have a close look at the food labels.

Can you identify all/some of the ingredients? (note chemicals and additives – look them up)

How much sugar and salt do they products contain? High or low?

Task

Your task is to create a poster/or TV advert exploring healthy lifestyles which offers ‘expert’ advice for others on eating habits, a healthy lifestyle and exercise.To ensure you adverts/posters are accurate and reliable you will need to use the information from this lesson and I have included some websites for you to use to do research.

The purpose of your advert is to highlight a healthy diet and lifestyle message, as well as this, you may choose to explain what can happen to the body when we don’t do these things or eat too much unhealthy food.

Think about how you want you poster to look or your advert to engage the viewer.
