Lesson 1: Introduction: nutritional needs across life stages

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about nutritional needs across life stages. Then check against the key terms: key terms from nutritional needs across life stages. 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 nutritional needs across life stages.
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: nutritional needs across life stages. 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.

Lesson 2: Core Concepts: nutritional needs across life stages

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on nutritional needs across life stages. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Nutritional needs change throughout life due to growth, development, activity levels, and physiological changes. Understanding these changes is essential for meal planning and public health advice.
Key Fact: Pregnancy: increased energy (200 kcal/day in third trimester), folate (prevents neural tube defects — 400μg supplement recommended pre-conception and first 12 weeks), iron (expanded blood volume), calcium and vitamin D (fetal bone development). Avoid: unpasteurised cheese, raw eggs, high-mercury fish, excess vitamin A.
Key Fact: Infancy (0-12 months): breast milk or formula provides all nutrients for first 6 months. Weaning (introducing solid foods) begins around 6 months — iron-rich foods are priority as iron stores deplete. Avoid: honey (botulism risk), salt, added sugar, whole nuts (choking).
Key Fact: Childhood (1-12 years): steady growth requires adequate energy, protein, calcium (bone development), and iron. Children have small appetites so nutrient-dense foods are important. Limit sugary snacks and drinks to prevent tooth decay.
Key Fact: Adolescence (13-18 years): rapid growth and puberty increase needs for energy, protein, calcium (peak bone mass development), iron (especially girls due to menstruation), and zinc. Teenagers often have poor diets — skipping meals, high fast food consumption.
Key Fact: Adulthood (19-64 years): nutritional needs are relatively stable. Focus on maintaining healthy weight, meeting 5-a-day, limiting saturated fat, salt, and sugar. Women of childbearing age need adequate folate and iron.

Extended Answer

Extended question: Full-Mark Response Compare the nutritional needs of a pregnant woman and an elderly person, explaining why their requirements differ. [12 marks] <div class="

Pregnant women and elderly people have significantly different nutritional needs, reflecting their contrasting physiological states — one supporting new life, the other managing age-related decline. Energy needs differ markedly. Pregnant women need only slightly more energy (approximately 200 kcal/day extra in the third trimester), while elderly people need fewer calories due to reduced BMR and activity levels. However, both groups must achieve high micronutrient intake within their energy allowance — requiring nutrient-dense foods. Folate is critical in pregnancy (preventing neural tube defects; 400μg supplement recommended) but less emphasised for elderly people. Conversely, B12 is a key concern for elderly people (reduced absorption from low stomach acid) but less critical in pregnancy. Iron needs are high in pregnancy (expanded blood volume and fetal stores) but less increased in elderly people. Calcium and vitamin D are important for both — in pregnancy for fetal bone development, in elderly people for preventing osteoporosis. Elderly people have reduced vitamin D synthesis from sunlight, making dietary sources and supplements more important. Protein needs differ: pregnancy re

Exam Tips: Always link life stage nutritional needs to specific nutrients and their functions | Give specific food sources for each nutrient at each life stage | Consider practical as well as nutritional aspects (e.g. texture for weaning, budget for elderly)
Common Errors: ✗ Pregnant women should eat for two. ✓ Energy needs increase only slightly (approximately 200 kcal/day in the third trimester). However, micronutrient needs increase significantly — folate, iron, calcium, and vitamin D requirements are much higher. Quality of diet matters more than quantity. ✗ Breastfeeding is always best for babies. ✓ Breast milk provides ideal nutrition and antibodies, and is recommended by the WHO. However, some mothers cannot or choose not to breastfeed. Infant formula provides adequate nutrition and is a safe alternative. The key is informed choice and adequate nutrition for the baby. ✗ Elderly people naturally eat less and this is fine. ✓ While energy needs decrease, m
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how nutritional needs across life stages connects to another Food Preparation and Nutrition topic you have studied
  • Real-world: research one real-world use or example of nutritional needs across life stages
  • Critical: "What are the limitations of the models used in nutritional needs across life stages?"
