This module provides an in-depth exploration of the fundamentals of nutrition, equipping you with the skills to critically evaluate key concepts, research data, and scientific arguments in the field. You’ll examine essential, conditionally essential, and non-essential nutrients, as well as gene-nutrient interactions and the impact of beneficial non-nutrients. A key focus is on dietary reference values, their sources, uses, and limitations, alongside an investigation into food sources of nutrients, toxins, and anti-nutrients. You’ll also explore how food production, supply, and preparation influence nutrient composition, as well as the digestion, absorption, and metabolic fate of nutrients. Understanding the role of diet across the lifespan, alongside mechanisms like energy balance, nutrient storage, homeostasis, and immunity, will provide a strong foundation for applying nutritional knowledge in health and disease. This module develops your ability to analyse and apply nutrition science, an essential competency for careers in nutrition, research, and public health.
