Junk food can give you depression

Eating foods high in trans-fats and saturated fats increases the risk of depression, according to a Spanish study, confirming previous studies that linked "junk food" with the disease.

Researchers also showed that some products, such as olive oil, which is high in healthy omega-9 fatty acids, are useful in the fight against the risk of mental illness.

Authors of the wide-reaching study, from the universities of Navarra and Las Palmas de Gran Canaria, followed and analyzed the diet and lifestyle of over 12,000 volunteers over six years.
