During this course you will come in contact with food and applicants with a medically diagnosed food allergy (note: not a food intolerance) should be aware of this.

Public Health Nutrition involves the promotion of good health through nutrition and the primary prevention of nutrition-related illness in the population.

It focuses on applying food and nutrition knowledge, policy and research to improving the nutritional health of the population and high-risk or vulnerable subgroups within the population.

This public health nutrition degree has an international perspective. It examines how global, national and local community programmes can be designed to improve the nutritional status of the population as a whole and those at particular risk.

There are employment opportunities for nutrition experts in the agri-food production and retail industries, as well as in nutrition product sales and marketing.

Several government agencies and bodies also employ expert nutritionists. The growing appreciation of the role of nutrition in public health is increasing the demand for graduates in public health nutrition.

The study of nutrition draws on a range of subjects, including the basic sciences, biochemistry, cell and molecular biology, immunology, microbiology and physiology.

The course will provide you with integrated training in the science of nutrition and its applications to human health and well-being, both at the individual and community level. You’ll learn about nutrients in food, the role of nutrients in the body and the relationship between diet, health and disease.

The skills and competencies you’ll develop will be enhanced and reinforced by a research project in Year 3.

Study Abroad Opportunities

In Year 3, you can complete your research project in Europe through the Erasmus programme and in Year 4, you can choose to undertake your work placement in Europe through the Erasmus programme.

Work Placement

In Year 4, students have the opportunity to undertake a 36 to 52-week professional work placement. Through this professional placement, you’ll gain real-life work experience.

Professional Accreditation

Upon successful completion of the course, you’ll be eligible to register as an Associate Nutritionist with the UK Voluntary Register of Nutritionists (UKVRN) conferred by the Association for Nutrition. Three years further relevant experience will enable you to apply for Registered Nutritionist status.

This is a full-time course and, depending on the week, students may have 15-25 hours of lectures/labs across all 5 days of the week.

Equipment Specifications 

During Year 1 of the course you will be required to obtain the following items to complete the course work (approximate prices are included): Lab Coat, Safety Goggles and Manual (€60), Hepatitis Vaccinations (€90), Immunity Testing (€20), Chef’s Uniform & Shoes (€100) and Knife Set (€30).
