You may have heard about a recent study correlating the consumption of trans fats to an increase in aggressive behavior; now a newer study correlates the consumption of ‘junk food’ to feelings of depression.
The journal Public Health Nutrition recently published this study, claiming that people who regularly eat junk food such as doughnuts, pizza, hamburgers and other fast food, can be linked to an increase in depression levels. The same study also found that people who regularly consume junk foods tends to be more sedentary, smoke, eat poorly, and work more than 45 hours per week.
Though this is just preliminary research, researchers suggest that people should be careful with how much junk food they eat, as it affects both their physical and mental health. The study was performed on 8.964 people without depression and free of antidepressant medication. The study tracked their mental health and diets for about six months. After this period of time, 493 participants were depressed or were taking antidepressants. The researchers analyzed their diets and found that the ones who ate the most junk food were 51% more likely to develop depression than the people who ate the least junk food.
An earlier study by the Mayo Clinic reported similar findings. This study found that people who consumed many fried foods, processed meats, desserts and high-fat dairy foods had an increased risk of depression symptoms. Coupled with the previous study linking trans fats to aggressive behavior, the risks of eating unhealthy foods just got a lot worse.
