背景：水果和蔬菜的摄入量较高，富含微量营养素，与更好的心理健康有关。然而，烹饪或加工可能会减少这些重要微量营养素的可用性。这项研究调查了与加工（煮熟或罐装）水果和蔬菜相比，生水果和蔬菜的摄入量与年轻人心理健康之间的差异。研究方法：在一项横断面调查设计中，422名18-25岁的年轻人居住在新西兰和美国的66.1%的女性完成了一项在线调查，该调查评估了生与熟/罐头/加工水果和蔬菜的典型消费量，消极和积极的心理健康状况，（抑郁症状、焦虑、消极情绪、积极情绪、生活满意度和繁荣）和协变量（包括社会经济状况、体重指数、睡眠、体力活动、吸烟和饮酒）。结果如下：控制协变量，生水果和蔬菜摄入量（FVI）预测减少抑郁症状和更高的积极情绪，生活满意度和繁荣;加工FVI只预测更高的积极情绪。与更好的心理健康相关的前10种生食是胡萝卜，香蕉，苹果，深色绿叶蔬菜，如菠菜，葡萄柚，生菜，柑橘类水果，新鲜浆果，黄瓜和猕猴桃。结论：当控制协变量时，原始FVI，而不是处理后的FVI，显著预测更高的心理健康结果。应用包括推荐食用生水果和蔬菜，以最大限度地提高心理健康益处。
Background: Higher intakes of fruits and vegetables, rich in micronutrients, have been associated with better mental health. However, cooking or processing may reduce the availability of these important micronutrients. This study investigated the differential associations between intake of raw fruits and vegetables, compared to processed (cooked or canned) fruits and vegetables, and mental health in young adults. Methods: In a cross-sectional survey design, 422 young adults ages 18–25 (66.1% female) living in New Zealand and the United States completed an online survey that assessed typical consumption of raw vs. cooked/canned/processed fruits and vegetables, negative and positive mental health (depressive symptoms, anxiety, negative mood, positive mood, life satisfaction, and flourishing), and covariates (including socio-economic status, body mass index, sleep, physical activity, smoking, and alcohol use). Results: Controlling for covariates, raw fruit and vegetable intake (FVI) predicted reduced depressive symptoms and higher positive mood, life satisfaction, and flourishing; processed FVI only predicted higher positive mood. The top 10 raw foods related to better mental health were carrots, bananas, apples, dark leafy greens like spinach, grapefruit, lettuce, citrus fruits, fresh berries, cucumber, and kiwifruit. Conclusions: Raw FVI, but not processed FVI, significantly predicted higher mental health outcomes when controlling for the covariates. Applications include recommending the consumption of raw fruits and vegetables to maximize mental health benefits.
