Could depression be caused by your diet? The link between unhealthy eating habits and chronic disease and disorders, including type 2 diabetes, cardiovascular disease, obesity and increased incidence of stroke, are well known. But, what about emotional wellbeing?
There is a growing body of evidence showing a strong connection between mental and emotional health, and a diet dominated by processed foods and refined sugar.
The link between sugar and depression
Research is beginning to make the link between sugar’s ability to raise levels of throughout the brain and body to higher incidences of . For example, a study published in the JAMA Psychiatry discovered that .
Another study found that patients who took medication to reduce inflammation due to autoimmune or inflammatory disease were less likely to develop symptoms of depression.

Reducing your intake of sugary foods and replacing them with anti-inflammatory choices can improve your mood.
Simple, refined carbohydrates have been in the spotlight in recent years for their lack of nutrients and contributions to the growing obesity epidemic. But Columbia University researchers wanted to find out if those could also spark depression.

Published in the , the researchers noted that their study also showed the opposite to be true: women consuming a diet high in whole grains and healthy produce reduced their risk of depression.

Those individuals who did not previously suffer from depression were not affected in the same way, although there is evidence that artificial sweeteners can significantly lower serotonin levels in the brain.
Choosing a healthy diet to promote mental health
Nearly all scientific studies examining the link between poor diet and mental illnesses like depression have been focused on a specific food. But research published in the looked at the diets of 3,000 people and found that while those who ate primarily whole foods saw their rate of depression drop.
Choosing a healthy diet dominated by whole foods, complex carbohydrates and natural fruit-derived sweeteners not only helps you manage your weight and reduce chances of serious illness, but it can improve your mental health as well. Clear your kitchen of processed foods, sugary snacks and artery-clogging trans fats. Not only will you improve your physical health, but you can expect to see your mood brighten as well.
