This KS4 lesson develops students’ understanding of macronutrients and micronutrients, with a strong focus on how micronutrient deficiencies impact health. It builds on KS3 foundations while preparing learners for GCSE‑level analysis and application.

Students explore the functions, sources, and importance of key nutrients before examining real‑world deficiency cases such as iron deficiency, vitamin D deficiency, and calcium deficiency. Through structured tasks and scenario‑based questions, they practise identifying nutritional risks and suggesting evidence‑based dietary improvements.

The lesson strengthens students’ ability to:
*Understand nutrient roles in the body
*Recognise symptoms and consequences of deficiencies
*Apply nutritional knowledge to diet analysis and problem‑solving
This resource supports confident, exam‑ready reasoning and helps students link nutrient intake to long‑term health.
