水果可以抗抑郁

Populations are rapidly ageing worldwide， and there is an increased prevalence of late-life depressive symptoms among older adults such as depressed feelings， lack of pleasure. This has been related to underlying neurodegenerative changes in the brain associated with ageing. The growing imperative to keep older adults in good health has spurred extensive research into approaches that could prevent late-life depression. Could specific diet or food items consumed earlier in life have an impact on mental well-being in later years？

In a longitudinal study conducted by the Yong Loo Lin School of Medicine， National University of Singapore， involving 13，738 participants from the large population-based Singapore Chinese Health Study that tracked participants through their mid-life to later life spanning about 20 years， researchers found that participants who consumed higher quantities of fruitsb936ab13c42d3d7ca4cd39636ba933577303d9add052f19bc2bb537311be625c earlier in life exhibited a reduced likelihood of experiencing depressive symptoms later in life.

At the initial stage of the study from 1993 to 1998， when participants were of average age of 51 years， they were asked to answer a structured questionnaire on how often they consumed a standard serving size of each food item daily， for 14 fruits and 25 vegetables. In 2014 to 2016， when participants were of average age of 73 years， depressive symptoms were examined using a standard test （Geriatric Depression Scale） and 3，180 （23.1%） participants who reported having five or more symptoms were considered to have depression in our study. After adjusting for factors that could potentially confound the relationship， including medical history， smoking status， level of physical activity， sleep duration， and ageing-related factors， the team found that higher consumption of fruits， but not vegetables， was associated with lower odds of depressive symptoms in a stepwise manner.

These findings suggest that promoting fruit consumption for individuals in mid adulthood， typically defined as ages 40 to 65 years， could yield long-term benefits for their mental well-being at late adulthood beyond 65 years. Hence， the study’s results hold significant implications for public health education and initiatives to make fruits more accessible for the general population.

1. D。解析：细节理解题。材料第一段的第一句提到“全世界人口正在迅速老龄化，晚年抑郁症状如抑郁情绪、缺乏快乐的患病率在老年人中上升”。D选项“不快乐的”与材料内容相符，故选D。

2. D。解析：推理判断题。根据材料第二段的“13，738 participants”和“their mid-life to later life spanning about 20 years”，我们可知有13738人参加了这个研究，并且这个研究跨越了20年。这说明了这个研究的可信度。D选项“证明可信度”与材料内容相符，故选D。

3.C。解析：细节理解题。根据材料第三段的“At the initial stage of the study from 1993 to 1998”“In 2014 to 2016”“the team found that...”，我们可知第三段主要是聚焦研究的过程。C选项“研究的过程”与材料内容相符，故选C。

4. B。解析：推理判断题。材料最后一段的最后一句提到“研究结果对公共卫生教育和倡议有着重大意义，能让更多的人吃上水果”，由此可知现在还有很多人是吃不上水果的。B选项“现在很多人几乎无法获得水果”与材料内容相符，故选B。
