Topic Synopsis
This topic covers the nutritional role of protein as a macronutrient, including its types, structure, functions, sources, and the consequences of deficiency.
Key Concepts & Core Principles
- Historical influences: How events like the Roman invasion, the Crusades, and the British Empire introduced new ingredients (e.g., spices, sugar, tea) and cooking methods (e.g., roasting, baking).
- Cultural and religious factors: How beliefs (e.g., halal, kosher, vegetarianism in Hinduism) shape food choices, meal patterns, and festival foods (e.g., Christmas pudding, Easter eggs).
- Technological advancements: The impact of inventions like the refrigerator, canning, and microwave on food preservation, storage, and preparation methods.
- Globalisation and migration: How movement of people (e.g., Indian, Chinese, Caribbean communities to the UK) has introduced new cuisines and fusion dishes (e.g., chicken tikka masala).
- Social and economic changes: How factors like the Industrial Revolution, women in the workforce, and convenience foods have altered meal structures (e.g., ready meals, eating out).
Exam Tips & Revision Strategies
- Ensure you can classify protein sources as either animal or vegetable
- Be prepared to explain the difference between HBV and LBV proteins
- Link protein intake to its specific functions in the body, such as growth and repair
Examiner Marking Points
- Distinction between High Biological Value (HBV) and Low Biological Value (LBV) proteins
- Understanding of protein structure
- Functions of protein in the body
- Consequences of protein deficiency
- Identification of animal and vegetable sources of protein
