Healthy Eating, a Balanced Diet and Body Image
The material covered in this PowerPoint provides a good introduction to Nutrition and Health.
It focuses on the issues of healthy eating, a balanced diet, body image, obesity and eating disorders.
This PowerPoint could be used to introduce CoPE Module 7: Healthy Eating and links well to challenges 2 and 9.
Teachers could use the information and issues covered on the following slides as a starting point for research projects, discussions or oral presentations.
For example, in relation to BMI and weight to height ratio, students could collect data as part of a survey to work out BMI, calculate the average BMI of their class and use ICT to create graphs or charts to show their findings.

2. A healthy diet: the basics
Healthy diets are balanced in the context of:
Proteins: build muscles and cells
Carbohydrates (starch and sugars): energy
Fats and oils: cell membranes and energy
Vitamins and minerals: health
Fibre: helps food move through the body
Water: hydration of the body

Carbohydrates: potatoes, rice, pasta, bread and alternatives
Fruit and vegetables: fresh, frozen and tinned all count towards your five a day

10. Obesity How would you describe an obese person?
Where does being overweight stop and obesity start?
Orb/0912/000370

11. Obesity is also malnutrition
However, it can be linked to a person’s genes. Some families are more likely to become overweight without dietary control – particularly when linked with poor exercise routine.

12. The effects of obesity
Too much food and too little exercise can cause obesity and other health problems:
Arthritis: worn joints
Diabetes: high blood sugar level
High blood pressure
Heart and blood vessel disease (cardiovascular)

13. It’s a matter of balance
To maintain your weight:
Does a bricklayer need to eat more than a teacher?
Do Eskimos need to eat more high-energy foods than us?
Energy intake (from food)
Energy output (exercise)

To calculate your BMI:
<18.5 underweight
normal weight
overweight
30+ obese
BMI
Weight (kg)
