Lesson Structure

1. Introduction (5 minutes)

• Begin with a stimulating question: “What do you think defines a wholefood versus an ultraprocessed food? Why does it matter?”
• Brief class brainstorm to gather initial ideas.
• Introduce the lesson focus: exploring the differences, impacts on health, and health equity considerations in New Zealand.

2. Explain and Compare: Wholefoods vs Ultraprocessed Foods (10 minutes)

• Present clear definitions:
• Wholefoods: Foods that are minimally processed and remain close to their natural state (e.g., fresh fruits, vegetables, nuts, seeds).
• Ultraprocessed foods: Industrial formulations made mostly or entirely from substances extracted from foods, containing additives and little whole food content (e.g., sugary drinks, fast foods, pre-packaged snacks).
• Use a comparison chart visually highlighting nutrient density, fibre content, additives, and typical price points.
• Discuss briefly the typical health impacts associated with high consumption of ultraprocessed foods (e.g., obesity, diabetes, chronic diseases).

3. Consumer Choices and Health Implications (10 minutes)

• Show a short video or infographic focused on New Zealand’s consumption patterns and health statistics relating to processed food intake.
• Facilitate a think-pair-share activity: students discuss factors influencing consumer choices (e.g., cost, advertising, convenience, cultural preferences).
• Share insights with the whole class.

4. Health and Equity Discussion (10 minutes)

• Provide a case study example or scenario about communities in New Zealand with limited access to affordable wholefoods (e.g., rural areas, low socioeconomic groups).
• Pose the question: “How do these factors influence health outcomes and equity? What responsibilities do individuals and society have?”
• Record students’ ideas on sticky notes and group under themes such as socio-economic barriers, cultural influences, and policy.

5. Reflection & Strategy Development (7 minutes)

• Individually, students write a brief reflection in their journals on:
• Their personal food choices.
• Steps they could take to make healthier choices considering their context.
• Suggestions to improve access and equity related to healthy food in New Zealand.
• (Optional) Ask a few students to share reflections.

6. Wrap-up and Homework (3 minutes)

• Summarise key points and emphasise the importance of understanding the relationship between food type, health, and equity.
• Homework: Research and bring an example of a New Zealand product that is either wholefood or ultraprocessed and be ready to explain its health and equity implications for next lesson.

---

Assessment and Feedback

• Formative assessment through observation of group discussions and think-pair-share participation.
• Evaluate students’ reflective journal entries for understanding and personal application.
• Use questioning during wrap-up to assess comprehension.
• Provide constructive feedback encouraging deeper analysis in subsequent lessons.

---

Teacher Notes and Differentiation

• Support English language learners by providing key vocabulary lists in advance (e.g., ultraprocessed, equity, additives).
• Encourage critical thinking by challenging students to relate concepts to their own lives and to New Zealand’s unique cultural and social context.
• For students with advanced interest, offer extension questions on policy responses or global food industry influence.
• Ensure culturally responsive pedagogy by incorporating Māori perspectives on food sovereignty and concepts of wellbeing where relevant.
