Balanced Eating

Overview

Today students will explore what a balanced diet looks like for Year 12 needs and preferences. They will use hands-on tools to build, test, and improve food choices, linking diet decisions to short- and longer-term wellbeing.

Learning intentions

• Students will identify nutrients and food groups needed for a balanced diet for adolescents/young adults.
• Students will compare real meal/snack options against balanced-diet criteria.
• Students will build a balanced meal plan using practical portioning and mindful choices.
• Students will reflect on how diet choices can support hauora (physical, mental, and social wellbeing).

Success criteria

• I can describe key nutrients and why they matter for wellbeing.
• I can evaluate a food plan using clear criteria (balance, variety, portions, and added sugar/salt).
• I can create an improved balanced meal/snack plan that fits my needs and context.
• I can explain how my plan supports wellbeing and what I would change next.

Curriculum links

• Health Education: Hauora and health promotion through wellbeing-focused choices.
• NCEA AS91237 — identify a wellbeing issue, develop a workable plan using SMART goals, implement, and evaluate effectiveness.
• Students will use a socio-ecological lens by considering personal preferences alongside family/school/community influences on food choices.

Lesson structure (50 minutes)

1. 0–5 min · Hook (Hands-on prompt). Teacher places 6–8 “food card” sets (or printed photos) around the room labelled “Energy”, “Growth/Repair”, “Protection”, “Energy release”, “Body functions” and asks students to do a quick gallery walk and pick 2 cards they think belong in a balanced diet. Students record which foods they chose and a one-line reason.

2. 5–15 min · Direct teach (Balanced diet for Year 12). Teacher introduces a balanced-diet framework: variety across food groups, adequate protein, fibre-rich carbohydrates, healthy fats, hydration, and limiting high sugar/salt/ultra-processed foods; then connects diet to physical wellbeing and energy/mood/sleep routines (hauora). Students complete a short “nutrient match” at their desk: choose which nutrient role best fits 4 example foods.

3. 15–25 min · Model evaluation (Micro-check). Teacher demonstrates evaluating one sample day (teacher-prepared menu) using a simple checklist: balance across food groups, portion appropriateness, fibre vs refined foods, water vs sugary drinks, and “sometimes foods” limits. Students use the same checklist to score a second sample day (pair work) and choose one “best improvement” suggestion.

4. 25–40 min · Hands-on build (Meal plan lab). Teacher explains the task: create a balanced meal and 1–2 snacks for a “real day” scenario (e.g., after school training, study-heavy day, or part-time work). Students use physical tools: portion plates (paper plates/laminated portion guides), ingredient/food cards, and a “SMART goal” template for one diet-related improvement (e.g., “I will include a fibre-rich snack at 3pm at least 4 days this week”). Students must justify choices in one or two sentences using nutrient roles and wellbeing.

5. 40–47 min · Swap & refine (Peer feedback). Students trade plans with another pair and give feedback using two prompts: “One thing that is balanced” and “One change that would improve wellbeing.” Each pair revises one item (food choice or portion) and updates their SMART goal wording if needed.

6. 47–50 min · Exit ticket (Evaluation reflection). Students answer: “Which nutrient role matters most in your plan and why?” and “One real barrier you might face (time, cost, availability, preferences) and one strategy to overcome it.”

Resources

• Food card set (photos or printed labels) representing common NZ foods
• Portioning tools: paper plates and/or laminated portion guide charts
• Balanced-diet criteria checklist (1 page)
• Nutrient role cards or mini “nutrient match” sheet
• SMART goal template (diet/behaviour focused)
• Scenario cards (training day, study day, weekend, shift work)
• Pens, highlighters, and scrap paper
• Timer and teacher sample menus

Assessment

• Formative: observation during pair evaluation (check for correct use of nutrient roles and balanced criteria).
• Formative: teacher circulates during meal plan lab to see if students can justify choices using wellbeing links.
• Summative within the lesson: exit ticket demonstrating nutrient role understanding and realistic next-step planning (supports AS91237 planning/evaluating mindset).

Differentiation

• Support: provide sentence starters (“I included ___ because it provides ___ which supports…”) and a partially completed SMART goal template.
• Support: offer an “easier card set” with fewer options and clearer healthier/sometimes labels.
• Extension: challenge students to redesign their plan for a different constraint (e.g., lactose intolerance, budget limit, vegetarian preferences) while keeping balance and justifying adjustments.
• EAL/SEN: allow oral justification with a peer scribe; reduce writing load by using a graphic organiser (nutrient role → evidence from their plan → wellbeing link).
