    Study Notes

    Innate Factors

    • Food choices are shaped by context and innate biological factors.
    • There is an innate preference for sweetness.
    • Children can detect flavour in the womb.
    • Other biological factors that influence food choices include genetics, brain, and psychology.

    The Brain and Eating Behavior

    • The brain is the primary organ involved in regulating eating behavior, specifically:
      • Cognitive System: Involved in thinking and decision-making related to food.
      • Homeostatic System: Regulates the body's internal balance, including hunger signals.
      • Reward System: Influences pleasure and motivation related to food.

    The Environment

    • The food environment has a significant impact on our eating behavior.
    • Since the 1980s, obesity rates have skyrocketed, highlighting the influence of environmental changes over genetic changes.

    Food Environments

    • Food environments form a component of food systems, which includes:
      • Food supply chain
      • Food environments
      • Consumer behavior
    • Examples of food environment interventions include:
      • Educational campaigns
      • Environmental defaults (choice architecture)
      • Nudging (retail level interventions)
      • Front-of-package labels (educational)

    Nudging

    • Nudging is a powerful strategy for influencing individuals' choices without coercion.
    • It involves changing the decision environment, also known as choice architecture.
    • Nudging techniques used in nutrition include:
      • Defaults: Setting healthier options as the default choice.
      • Order: Presenting healthier options first.
      • Accessibility/Visibility: Increasing visibility of healthier options.
      • Heuristic-based signaling/Evaluative labeling: Using simple cues to highlight healthy options.
      • Hedonic Enhancements: Making healthier foods more appealing.

    Front-of-Package Labels (FOPLs)

    • FOPLs aim to provide a quick and easy overview of a food product's nutritional value.
    • They aim to help consumers make healthier food choices in a fast and simple way.
    • Different FOPLs exist encompassing:
      • Reductive/Non-directive: Focus on highlighting positive nutritional aspects.
      • Nutrient Directive/Interpretative: Highlight specific nutrients linked to health.
      • Food Directive/Interpretative: Focus on food groups rather than nutrients.
    • The effectiveness of FOPLs is under debate, with some suggesting they could lead to subtle increases in healthier food consumption.

    Warning Labels

    • Warning labels are a form of FOPLs used to notify consumers about potentially unhealthy aspects of food products.
    • They are currently implemented in many Latin American countries, including Chile, Mexico, Uruguay, and Argentina.
    • They are also set to be implemented in Canada by 2026.
    • Data from Chile indicates potential benefits, including a reduction in total calories purchased and a decrease in products labeled high in unhealthy ingredients.
