A team of researchers from England and France found that dietary patterns over a five-year period had a significant effect on the risk of feeling depressed. People eating a predominantly natural-foods diet of mostly vegetables, fruits, fish, and whole grains were one-fourth less likely to have depression. Those eating mainly processed foods, including processed meats, refined grains, fried foods, high-fat dairy products, and sweetened desserts were more than 50 percent more likely to feel depressed. The natural-foods diet is richer in vitamins, minerals, and good fats that help maintain healthy moods. (Akbaraly TN, Brunner EJ, Ferrie JE, et al.
