Diploma in Human Nutrition

This diploma is a science-based introduction to how the body uses food. It begins with the three energy-yielding macronutrients — carbohydrates, proteins and lipids — and the workings of the digestive system, then goes deeper into each: the groups of carbohydrates, the main types of amino acids and how proteins are synthesised and structured, and the roles of fatty acids and the compounds derived from them. Later modules trace the metabolic pathways for carbohydrates, lipids and proteins, survey vitamins and minerals such as vitamin C, vitamin E and selenium, and explain the structure and function of antioxidants.
