Fast food and bakery foods linked to depression

A new study published in the Public Health Nutrition journal has shown eating commercial bakery goods (fairy cakes, croissants, doughnuts, etc.) and fast food (hamburgers, hotdogs and pizza) is linked to a greater risk of suffering from depression.

According to scientists from the University of Las Palmas de Gran Canaria and the University of Granada, consumers of fast food were 51% more likely to develop depression compared to those who ate little or none. And the more fast food consumed, the greater the risk of depression.

The study also found that people who ate the most fast food and commercial baked goods were more likely to be single, less active and eat less fruit, nuts, fish, vegetables and olive oil. Smoking and working more than 45 hours per week were other prevalent characteristics of this group.

Even eating small quantities of baked goods was linked to a significantly higher chance of developing depression.

The study consisted of 8,964 participants that had never been diagnosed with depression or taken antidepressants. They were assessed for an average of six months; 493 were diagnosed with depression or started to take antidepressants.

This new data supports the results of previous research that found a 42% increase in the risk of depression associated with fast food consumption.

Little is known about the role that diet plays in developing depressive disorders. Previous studies suggest that certain nutrients have a preventative role including B vitamins, omega-3 fatty acids and olive oil. The Mediterranean diet has also been linked to a lower risk of developing depression.
