- Aims to shape society to better suit health
- Effective when dealing with long term or global issues
- Will fail if aims are too bold!
- Effective PH measures strike a balance between these
- Narrow Approach
- Individuals own lifestyle determines risk of disease
- Aims to advise people to change their own behaviour
- Effective if disease related to individuals behaviour
- Will fail if individual not motivated to change

- Public health nutrition is:
- Promotion of good health through prevention of nutrition related illness in the population
- Design of nutritional interventions in the population
- Inadequate intake
- Results from poverty, politics and lack of education
- Poor access to food and follows disease
- Epidemiology:The study of the distribution and determinants of health-related states or events in specific populations, and the applications of this study to control health problems
- Nutritional epidemiology is the main source of information for PHN.
- There is a relationship between exposure and outcome. This could be simple or complex.
- The relationship between diet and disease is rarely straight forward.
- Measuring dietary intakes in a large population is difficult!
- Public Health Interventions
- Health Promotion
- This allows populations to increase the control they have over factors that affect their health
- E.g. Change-4-Life, 5-A-Day, Traffic Light System
- Changing behaviour through persuasion, advice, recommendations and guidance.
- Fortification and supplementation
- Supplementation requires education and an active choice - narrow.
- Fortificatio ensures all consumers have a good intake but takes away choice - broad.
- Health Promotion
- Broad Approach
