Lesson Objectives

By the end of this chapter, students should be able to:

1. Key Words and Concepts

Learn these definitions carefully. Examiners often award full marks for precise wording.

Food: Any substance (solid or liquid) eaten or drunk by living organisms to give energy and nourishment and to support growth, repair and maintenance of the body.
Nutrition: The process by which living organisms obtain and use food for growth, energy and health. It includes ingestion, digestion, absorption and assimilation.
Nutrients: The chemical substances in food that the body needs: carbohydrates, proteins, fats, vitamins, minerals and water.
Balanced diet: A diet containing all the essential nutrients in the right proportions for good health.
Malnutrition: A condition caused by an unbalanced diet (undernutrition or overnutrition).
Aesthetics of food: The visual appeal, colour, texture, arrangement and presentation of food.

2. Concept of Food and Nutrition

Food and nutrition are closely related but different:

Main Functions of Food

Energy-givingCarbohydrates and fats
Body-building and repairProteins
Protection and regulation of body processesVitamins and minerals
Essential for all body processesWater

🔦 Spotlight — Food as Art

Artists such as Paul Cézanne painted apples and oranges not only as food but to explore form, colour, texture, light and composition. Understanding the structure of food helps both in nutrition and in realistic drawing.

🎨 Classroom Activity 1: Observational Drawing (15 minutes)

Provide simple fruits or vegetables such as an apple, banana or carrot.

  • Make a 10-minute contour-line drawing, focusing on shape and form.
  • Make a 5-minute shaded drawing that shows texture and highlights.
  • Discuss: how does understanding the structure of food help both nutrition and realistic drawing?

Key Importance

Artistic Perspective

🎨 Classroom Activity 2: Food Presentation Design (20 minutes)

In groups, use plain biscuits or crackers, fruits or coloured paper.

  • Create an attractive food arrangement or collage using balance, contrast and harmony.
  • Present your design and explain your choices.
  • Discuss: how does visual appeal influence people's willingness to eat nutritious food?

4. Relationship with Other Subjects

Food and Nutrition is an interdisciplinary subject:

SubjectRelationship with Food and NutritionFine Art connection
BiologyDigestion, absorption and metabolismDrawing biological diagrams of the digestive system
ChemistryComposition of nutrients, pH in foodColour-mixing experiments with natural food dyes
PhysicsHeat transfer in cooking; preservation methodsStill-life paintings showing reflections on utensils
Fine ArtFood presentation, colour theory, still-life drawingUsing food as subject matter
Home EconomicsMeal planning, budgeting, food hygieneDesigning table settings and layouts
AgricultureFood production and sources of nutrientsDrawing plants and food crops
MathematicsMeasuring ingredients, nutritional calculationsProportion and scale in food drawing
Exam tip: When asked to explain the relationship between food and nutrition and another subject, give a concrete link (for example Biology → digestion; Agriculture → food production), not a vague statement.

🎨 Classroom Activity 3: Interdisciplinary Mind Map (10 minutes)

In your sketchbook, make a colourful mind map showing how food and nutrition connects with at least four other subjects. Use symbols, small drawings and different colours.

5. Chapter Summary

  • Food is the substance we eat; nutrition is how the body uses it.
  • Main functions of food: energy-giving, body-building and repair, protection and regulation, and water for all processes.
  • Food gives energy, growth, repair, immunity, mental well-being and cultural meaning.
  • Food presentation is an art that uses colour, texture, balance and harmony to affect appetite.
  • Food and nutrition links with Biology, Chemistry, Physics, Fine Art, Home Economics, Agriculture and Mathematics.

Part A — Multiple Choice (10)

1. Which is a nutrient?

A. Protein

2. Food that repairs worn-out tissues is rich in:

A. Proteins

3. Vitamins and minerals mainly:

A. Protect and regulate body processes

4. Warm colours in food tend to:

A. Stimulate hunger

5. Which subject explains digestion and absorption?

A. Biology

6. Measuring ingredients links food and nutrition with:

A. Mathematics

7. The sources of food crops are studied in:

A. Agriculture

8. Overnutrition and undernutrition are types of:

A. Malnutrition

9. Which is part of nutrition?

A. Digestion

10. Water in the body is:

A. Essential for all body processes

Part B — Short Answer (8)

1. Differentiate between food and nutrition.

Food is the physical substance (solid or liquid) we eat or drink. Nutrition is the process by which the body obtains and uses that food for growth, energy and health (ingestion, digestion, absorption, assimilation).

2. State any three functions of food in the body.

Any three: energy-giving (carbohydrates and fats); body-building and repair (proteins); protection and regulation (vitamins and minerals); water for all body processes.

3. Explain why food presentation is important from both a nutritional and an artistic point of view.

Nutritional: attractive presentation encourages people to eat nutritious food and improves appetite. Artistic: plating, colour, texture and arrangement follow design principles and make food a visual experience.

4. Name two subjects that relate to food and nutrition and explain the connection for each.

Any two: Biology (digestion, absorption, metabolism); Agriculture (production of food crops); Chemistry (composition of nutrients, changes in cooking); Fine Art (still-life drawing, colour, presentation).

5. Define: (a) nutrients, (b) balanced diet, (c) malnutrition.

(a) Chemical substances in food that the body needs (carbohydrates, proteins, fats, vitamins, minerals, water). (b) A diet with all essential nutrients in the right proportions. (c) A condition caused by an unbalanced diet (too little or too much of certain nutrients).

6. List four reasons why food is important for human well-being.

Any four: provides energy; supports growth; repairs tissues; strengthens immunity; maintains health and prevents disease; supports mental well-being; cultural and social meaning.

7. How does colour in food affect appetite? Give an example.

Warm colours (red, orange, yellow) tend to stimulate hunger; cool colours (blue, green) can suppress appetite. A bright, colourful fruit salad looks more appetising than a dull plate.

8. Briefly explain how food and nutrition relates to Agriculture and to Mathematics.

Agriculture supplies the food crops and animal products that provide nutrients. Mathematics is used to measure ingredients, calculate nutritional values and work out proportions in recipes.
