Nutritionist job description

What does a Nutritionist do?

Nutritionists take a holistic view of a person’s lifestyle, dietary habits, and overall health, to provide their client with customised nutritional advice. 

After creating a nutritional plan, a Nutritionist will continue to monitor their client’s progress and any changes or improvements to their health.

Nutritionists often work in a preventative capacity, assisting people to identify and change dietary habits that could lead to future health problems. As a Nutritionist, you’ll have a strong understanding of the connection between diet and disease and how nutrition and lifestyle factors impact overall wellbeing.

In addition to providing nutritional assessment, advice and ongoing support to clients, Nutritionists may be involved in coordinating community health initiatives, promoting nutritional education and researching population health.

What is the difference between a Nutritionist and a Dietician?

A Nutritionist may hold a tertiary qualification in one of several fields including nutrition, food science or public health.
