Beyond Hangry: Mental Health and Diet

We all know the irritability we feel when our blood sugar dips with the delay of a meal. There is a growing set of research that indicates that the link between diet and mental health is much more than this transient change in mood.

The brain is the most sensitive organ to dietary changes. It requires high quality food to allow it to function optimally. Diets that are high in sugars and processed foods increase inflammation and oxidative stress, and result in significant changes in mood, memory and focus.

Nutritional psychiatry is a new field that helps us to understand the best way to protect our mental health through a healthy diet. Diet impacts “feel good” neurotransmitters in the brain as well as the “good bacteria” in our gut. A diet that is high in fruits and vegetables, and low in processed foods, helps us function at our best and helps our cognition. 

The Mediterranean diet has been thought to be a splendid example of a diet ideal for brain health. This diet is inspired by traditional cuisines in Greece, Spain and Italy. The cornerstones of this diet are many whole grains, legumes, fruits and vegetables, nuts and seeds and a smaller amount of meat and fish.

Coupled with being engaged in physical activity and meaningful social interaction, mindful attention to diet can help to protect mental health. Of course, diet alone cannot help to treat mental illness. If you suffer from depression or anxiety, reach out to your primary care provider.
