澳大利亚学者研究表明，受抑郁与焦虑困扰的女性应注意日常饮食结构，彻底告别加工食品。

     1月14日澳大利亚墨尔本大学学者报道，20岁至93岁女性中，情绪紊乱症状相当普遍。历时10年的跟踪调查结果显示，她们饮食结构以加工、精制以及高脂肪食品为主。

    “没有什么神奇食谱，”参与研究的费利斯·杰卡博士说，蔬菜、水果、全麦食品、低脂乳制品、瘦肉以及初加工食品有助身体健康，对保持良好精神状况也有裨益。

    研究结果在《美国精神病学杂志》（American Journal of Psychiatry）上发表。研究发现，“西方式”饮食，主要包括汉堡、匹萨、薯条、牛肉以及多糖食物等致情绪紊乱几率，比传统澳大利亚饮食高出50%。

传统澳大利亚饮食结构，主要包括蔬菜、水果、牛肉、羊肉、鱼以及全麦食品。以传统饮食为主的女性可减少30%出现情绪紊乱的几率。

    杰卡专家研究组10年来，跟踪研究1046名女性，分析饮食与精神疾病间的关系。研究人员说，925名女性不存在情绪紊乱，而121人为深度抑郁或焦虑困扰。

研究人员说，即便将年龄、体重、社会经济地位、教育、吸烟、饮酒等因素考虑在内，饮食结构与抑郁与焦虑等精神紊乱之间仍存在密切关系。（Bioon.com）

    OBJECTIVE: Key biological factors that influence the development of depression are modified by diet. This study examined the extent to which the high-prevalence mental disorders are related to habitual diet in 1,046 women ages 20–93 years randomly selected from the population.

METHOD: A diet quality score was derived from answers to a food frequency questionnaire, and a factor analysis identified habitual dietary patterns. The 12-item General Health Questionnaire (GHQ-12) was used to measure psychological symptoms, and a structured clinical interview was used to assess current depressive and anxiety disorders.

    RESULTS: After adjustments for age, socioeconomic status, education, and health behaviors, a "traditional" dietary pattern characterized by vegetables, fruit, meat, fish, and whole grains was associated with lower odds for major depression or dysthymia and for anxiety disorders. A "western" diet of processed or fried foods, refined grains, sugary products, and beer was associated with a higher GHQ-12 score. There was also an inverse association between diet quality score and GHQ-12 score that was not confounded by age, socioeconomic status, education, or other health behaviors.

    CONCLUSIONS: These results demonstrate an association between habitual diet quality and the high-prevalence mental disorders, although reverse causality and confounding cannot be ruled out as explanations. Further prospective studies are warranted.
