Cambridge O Level and IGCSE Combined Science develops a set of transferable skills including handling data, practical problem-solving and applying the scientific method. This Human nutrition unit is a core component of the Biology section of both syllabuses, exploring how humans obtain and process nutrients from food. Cambridge IGCSE Combined Science 0653 Biology covers Human nutrition as Topic B7[reference:2], including balanced diet, the sources and importance of seven nutrient groups, identification and functions of named digestive organs, five nutrition processes, physical and chemical digestion, enzyme routes and the functions of hydrochloric acid in gastric juice[reference:3].

📚 Complete Syllabus Coverage – New Syllabus (2026-2028)

Our Human nutrition lesson plans address all essential topics from the CAIE O Level Combined Science 5129 and IGCSE Combined Science 0653 new syllabuses, including:

Section 4.1: Diet

• Balanced Diet: Understanding that a balanced diet contains carbohydrates, proteins, lipids, vitamins, minerals, water and dietary fibre in the correct proportions[reference:4]
• Chemical Elements in Nutrients: Listing the chemical elements that make up carbohydrates (carbon, hydrogen, oxygen), proteins (carbon, hydrogen, oxygen, nitrogen, sometimes sulfur) and lipids (carbon, hydrogen, oxygen)[reference:5]
• Sources of Nutrients: Identifying the sources and functions of carbohydrates (energy source and store)[reference:6], proteins (growth and repair of tissues)[reference:7], lipids (energy store, insulation, cell membranes)[reference:8], vitamins, minerals (including iron for haemoglobin, calcium for bones)[reference:9], water and dietary fibre
• Food Tests: Performing and interpreting chemical tests for starch (iodine solution), reducing sugars (Benedict’s test), proteins (biuret test) and lipids (emulsion test)[reference:10]
• Energy Efficiency: Understanding why it is more energy efficient for humans to eat crop plants than livestock fed on crop plants[reference:11]
• Deficiency Diseases: Describing the effects of vitamin and mineral deficiencies – vitamin C (scurvy), vitamin D (rickets), iron (anaemia) and calcium (weak bones)

Section 4.2: Human Digestive System

• Organs of the Digestive System: Identifying in diagrams and images the main organs of the digestive system – alimentary canal (mouth, oesophagus, stomach, small intestine including duodenum and ileum, large intestine including colon, rectum and anus) and associated organs (salivary glands, pancreas, liver and gall bladder)[reference:12]
• Functions of Digestive Organs: Describing the functions of each organ in the process of digestion
• Physical Digestion: Understanding mechanical breakdown of food – chewing in the mouth, churning in the stomach, emulsification of fats by bile
• Chemical Digestion: Understanding the role of digestive enzymes in breaking down large, insoluble molecules into smaller, soluble molecules
• Digestive Enzymes: Describing the digestion of starch to maltose by amylase, maltose to glucose by maltase; the digestion of proteins to amino acids by proteases; and the digestion of lipids to fatty acids and glycerol by lipases[reference:13]
• Hydrochloric Acid in the Stomach: Explaining the two functions of hydrochloric acid – killing bacteria and providing the optimum pH for protease enzymes[reference:14]
• Bile: Understanding the role of bile in emulsifying lipids and neutralising stomach acid in the small intestine

Section 4.3: Absorption and Assimilation

• Absorption: Describing the absorption of digested food molecules through the wall of the small intestine into the bloodstream[reference:15]
• Adaptations of the Small Intestine: Understanding how the structure of the small intestine is adapted for absorption – large surface area (villi and microvilli), thin wall (one cell thick), rich blood supply
• Assimilation: Understanding the use of absorbed nutrients by the body – glucose for respiration, amino acids for protein synthesis, fatty acids and glycerol for lipid synthesis
• Egestion: Understanding the removal of undigested food (fibre) from the body through the anus
