Eating a diet high in processed food increases the risk of depression, research suggests. What is more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.

倫敦大學學院團隊的研究發現，吃很多加工食物會增加憂鬱症風險，而且吃大量蔬果與魚類的人，憂鬱症的風險較低。

They split the participants into two types of diet - those who ate a diet largely based on whole foods, which includes lots of fruit, vegetables and fish, and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat, refined grains and high-fat dairy products.

研究人員把參與者分成兩種飲食組別，第一組是大部分吃不加工食物的人，包括大量水果、蔬菜與魚類，第二組是大多吃加工食物者，例如加糖的點心、油炸食品、加工肉品、精緻穀物、高脂肪乳製品等。

After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic diseases, they found a significant difference in future depression risk with the different diets. Those who ate the most whole foods had a 26% lower risk of future depression than those who at the least whole foods.

考量性別、年齡、教育、身體活動、抽菸習慣、慢性病等因素之後，他們發現，飲食不同，未來罹患憂鬱症的風險也大有差異。吃最多不加工食物者，未來罹患憂鬱症的風險，比吃天然食物最少者低26%。

By contrast people with a diet high in processed food had a 58% higher risk of depression than those who ate very few processed foods.

相較之下，飲食多加工食物者，憂鬱症風險比非常少吃加工食物者高58%。
