  • Public Health Nutrition
    • Broad Approach
      • Takes the view that the risk of disease is determined by culture or society
      • 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
          • Will fail if cause of disease lies outside individuals control
    • 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
      • Will fail if cause of disease lies outside individuals control
    • Effective PH measures strike a balance between these
      • 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.
