Nutritionists help individuals and communities make the right food choices for a healthy diet. To do this, nutritionists consider the nutritive value of foods, the nutrients bodies need at different stages of development, and the role nutrients and diet play in health and disease prevention. They can also do research such as working on new food products, or examining the relationships between nutrients or dietary patterns and disease. However, nutritionists do not help treat disease through nutrition - that is the role of dietitians. This multidisciplinary course aims to give students a thorough understanding of human nutrition, to prepare students for a range of careers in the promotion of health and fitness at individual and community levels.
