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.
