Public Health Nutrition focuses on the promotion of good health through nutrition and the primary prevention of nutrition-related illness in the population. Public Health Nutritionists develop, implement and evaluate nutrition policies and programmes, generating the evidence base and applying scientific knowledge to ensure understanding of the impact of food and diet on health and wellbeing of people and communities, and improving the diet, nutrition and health of people and communities. With the increased number of the population suffering from, or at risk of developing, lifestyle-related chronic diseases, more individuals require assistance with nutritional management. As a result, there is an urgent need for suitably qualified individuals to work in the health sectors. Public health nutrition has been gaining popularity as an area of study to meet this growing demand.
