The Mediterranean Diet and Mental Health


There are limited studies currently available on the Mediterranean diet and its effects on mental health; however, there is some evidence which shows that the nutrients gained from this diet, such as antioxidants, omega 3 fatty acids, fibre and B-vitamins positively effect mood and brain function.


​What is missing from many studies is the impact that the Mediterranean lifestyle also has on mental health, which includes diet, lifestyle, social and cultural aspects. Although diet does play a part in treating mental illness, it is not the only aspect which should be considered.


Dietary Strategy

What a person eats directly affects functioning of the brain, and as a result, a person’s mood. The brain can only function at it optimal levels when a good diet rich in antioxidants, vitamins and minerals is consumed. A poor diet that is high in refined food has been shown in multiple studies to affect brain function and increase symptoms of disorders such as depression.


The Mediterranean diet is associated with reducing the risks of many chronic diseases, however there is currently limited research on the affects it has on mental health. Many components of the Mediterranean diet encourage healthy brain function such as omega 3 fatty acids, antioxidants and B vitamins. As well as this, the Mediterranean diet is rich in vitamins, minerals, polyunsaturated fatty acids and antioxidants which have been shown to have a positive impact on mental health.


How Diet Affects Mood

The gastrointestinal tract is lined with millions of nerve cells, making it more than just a place to digest food, but also a mood regulator. Around 95% of serotonin is produced in the gastrointestinal tract. The production of serotonin and the functioning of the neurons in the gastrointestinal tract are highly influenced by the intestinal microbiome which are directly affected by diet.
