Diet Depression?

According to a study led by a scientist at the University of Melbourne in Australia, it found out that a Western-style diet such as meats, fired foods, pizza, white bread, beer and sugar can increase the odds of depression by 52% and so a diet of high-fat and high-calorie processed foods may damage not only physical health but also mental health.
The study also reflected that diets made up of veggies, grass-fed meat, fruits, fish and whole grains reduced the odds of depression and anxiety disorders to 35% and 32% respectively.
As a conclusion, the study points out that nutrition affects brain chemicals, hormones, inflammation and the immune system.
