We’ve all felt the effects of food on our mood, so it would stand to reason that dietary intervention for mental health would be well studied and a regularly deployed treatment.

But this is far from reality, as historically, psychiatry was only concerned with what happened from the neck up.

In today’s episode, Jonathan is joined by Felice Jacka, Professor of Nutritional Psychiatry and Director of the Food & Mood Centre at Deakin University. Felice was the driving force behind the landmark study to determine if dietary intervention could help treat the symptoms of moderate to severe depression.

With her help, we dive into what the science suggests regarding the relationship between food and our mental health and what foods we can eat to improve it.
