The study, conducted on 3,500 middle-aged British civil servants, found that those who consumed large amounts of processed foods — such as sweetened desserts, fried food, processed meat, refined grains and high-fat dairy products — had a 58 percent higher risk of depression than those who ate very few processed foods, reports the BBC.

The scientists called for more research into the relationship between diet and mental health; but here’s one idea, based on common sense: Foods consisting of processed carbohydrates and sugars enter the bloodstream and get converted to energy very quickly, giving you that well-known “sugar rush.” But just as quickly, you come crashing down — both physically and mentally.
