Nutrition and Wellbeing Course

Nutritional interventions to support wellbeing

Could the key to unlocking mental health and wellbeing be as simple as what you eat? Get up to speed with the latest research. Learn how to upgrade your mental health and wellbeing, and nourish those in your care.

Developed by Professor Julia Rucklidge.


In Professor Julia Rucklidge’s wellbeing series, you’ll learn how to boost and enhance the different aspects of hauora (health) through psychology, lifestyle changes and the nutritional interventions explored in this course.

We all know there’s a relationship between what we eat and how we feel, but what does the science show us?

Explore the relationship between nutrition and wellbeing, and investigate the research-backed strategies that have been proven to maintain and improve our wellbeing.

Developed by clinical psychologist Julia Rucklidge (director of the UC Mental Health and Nutrition Research Lab), you'll explore the important role that wholefoods rich in micronutrients play in maintaining mental and physical wellbeing through the latest nutrition and wellbeing research.
