问题    Eating a diet high in processed (加工过的) food increases the risk of depression, a study suggests. What’ s more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
   Data on diet among 3500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet—those who ate a diet largely based on wholefood (全天然食物) , 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. After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic (慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
   Those who ate the most wholefood had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58% higher risk of depression than those who ate a diet low in processed food.
   Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by the lifestyle factor they had not accounted for. He also pointed in a paper that a Mediterranean diet was associated with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood of eating a Mediterranean diet is not very high.
   Dr. Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
   He added people’ s diets are becoming increasingly unhealthy. The UK population is consuming less nutritious, fresh produce and more saturated fats and sugars.
What do we know about the participants?
选项 A、They are of different ages from young to old.
B、They are from different walks of life.
C、They can choose the diet they like.
D、Their mental states are also affected by other factors.
答案D
解析 根据第四段第一句“Study author Dr．Archana Singh Manoux pointed out there was a chance that the finding could be explained by the lifestyle factor they had not accounted for．”可推知，影响整个结果的可能还包括生活方式在内的其他因素，即参与者的心理状况还受到别的因素的影响。选项A、B、C文中均未提及。故选D。
