Lesson 1: Introduction: diet-related health issues

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about diet-related health issues. Then check against the key terms: key terms from diet-related health issues. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: key terms from diet-related health issues.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: diet-related health issues. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Food Preparation and Nutrition because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: explain the key ideas of diet-related health issues

Your student states one thing they learned and one question they still have about diet-related health issues.

Lesson 2: Core Concepts: diet-related health issues

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on diet-related health issues. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Obesity: BMI over 30. Affects 28% of UK adults and rising in children. Caused by sustained positive energy balance (calories in exceed calories out). Increases risk of type 2 diabetes, heart disease, stroke, and certain cancers.
Key Fact: Type 2 diabetes: the body becomes resistant to insulin or doesn't produce enough. Strongly linked to obesity, physical inactivity, and diets high in sugar and refined carbohydrates. Management includes weight loss, exercise, and reduced sugar intake.
Key Fact: Cardiovascular disease (CVD): includes heart disease and stroke. Risk factors include high blood pressure, high LDL cholesterol, smoking, obesity, and physical inactivity. Diet influences: excess saturated fat raises LDL cholesterol; excess salt raises blood pressure; fruit and vegetables provide antioxidants.
Key Fact: Tooth decay (dental caries): caused by bacteria fermenting sugars to produce acid that erodes tooth enamel. Frequency of sugar consumption matters more than total amount. Prevention: reduce sugar frequency, brush twice daily with fluoride toothpaste, visit the dentist.
Key Fact: Iron-deficiency anaemia: most common nutritional deficiency globally. Particularly affects women (menstrual losses), teenagers (rapid growth), and vegetarians (non-haem iron is poorly absorbed). Symptoms: fatigue, pallor, breathlessness, poor concentration.
Key Fact: Osteoporosis: weakened bones prone to fracture. Linked to inadequate calcium and vitamin D intake, particularly in post-menopausal women. Prevention: adequate calcium, vitamin D, and weight-bearing exercise throughout life.

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: key terms from diet-related health issues. Define each in one sentence.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Work through the practice questions on the revision notes page for this topic.

Extended Answer

Extended question: Full-Mark Response Evaluate the role of diet in preventing cardiovascular disease. [12 marks] <div class="

Cardiovascular disease (CVD) is the UK's second leading cause of death, and diet plays a significant role in both increasing and reducing risk. The primary dietary risk factor is excessive saturated fat intake, which raises LDL ('bad') cholesterol. LDL cholesterol deposits in artery walls, forming plaques that narrow arteries (atherosclerosis), potentially leading to heart attacks and strokes. Replacing saturated fats with unsaturated fats (olive oil, oily fish) can lower LDL and raise HDL ('good') cholesterol, reducing CVD risk. Excess salt intake (UK average 8.4g/day vs recommended 6g/day) raises blood pressure, another major CVD risk factor. Processed foods contribute approximately 75% of dietary salt. Reducing salt intake by 1.6g/day could prevent approximately 5,000 deaths annually in the UK. Insufficient fruit and vegetable consumption means fewer protective antioxidants and less potassium (which helps lower blood pressure). The UK 5-a-day target is met by only about 30% of adults. Oily fish provides omega-3 fatty acids that reduce inflammation, lower triglycerides, and reduce blood clotting tendency. The recommended two portions per week (including one oily) is rarely met. H

Exam Tips: Always give specific dietary recommendations for each health condition | Use statistics where possible (e.g. 28% UK adult obesity rate) | Discuss prevention AND management of diet-related conditions
Common Errors: ✗ Obesity is simply caused by eating too much. ✓ Obesity results from a sustained positive energy balance, but the causes are complex: genetic predisposition, socioeconomic factors, food environment, psychological factors, and physical inactivity all contribute. Simplifying to 'eating too much' ignores the systemic factors. ✗ Only overweight people get type 2 diabetes. ✓ While obesity is the primary risk factor, type 2 diabetes can also occur in normal-weight individuals, particularly those with high visceral fat or genetic predisposition. BMI is not the only indicator of metabolic health. ✗ Tooth decay is only caused by eating sweets. ✓ Any fermentable carbohydrate (including bread, fruit,
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how diet-related health issues connects to another Food Preparation and Nutrition topic you have studied
  • Real-world: research one real-world use or example of diet-related health issues
  • Critical: "What are the limitations of the models used in diet-related health issues?"
