Nutritionists generally work in a preventative role on a one-to-one and a group basis with patients of all ages. Unlike dieticians who primarily work with people who are ill, nutritionists mostly work with people who are healthy.

Key responsibilities of the job include:

Qualifications and training required

To become a nutritionist it is necessary to gain a degree in nutritional science, dietetics, or food science; or alternatively a life sciences degree that incorporates human physiology and biochemistry.

A postgraduate qualification in nutrition can be helpful and is essential for candidates without a suitable first degree in nutrition or dietetics.
