This topic covers the nutritional and functional properties of protein, including its classification, sources, health implications, and its role in food preparation and science.
This topic explores the relationship between diet and health, focusing on how nutrients affect the body and the consequences of dietary imbalances. You'll learn about macronutrients (carbohydrates, proteins, fats) and micronutrients (vitamins, minerals), their functions, sources, and the effects of deficiency or excess. Understanding this is crucial for making informed food choices and for the NEA tasks where you must justify ingredient selections based on nutritional needs.
The topic also covers energy balance, basal metabolic rate (BMR), and physical activity level (PAL), which are key to weight management. You'll study diet-related health conditions such as obesity, type 2 diabetes, cardiovascular disease, and osteoporosis, and how dietary modifications can prevent or manage them. This knowledge is applied in practical cooking and when evaluating meals for specific life stages or health conditions.
Mastering this content is essential for the written exam (Paper 1) and for the non-exam assessment (NEA), where you may need to plan meals for individuals with specific dietary needs. It also underpins other topics like food choice, food science, and food safety, making it a foundational part of the course.
