香蕉被认为是富含多巴胺和钾的食物，但没有关于过量摄入香蕉引起的生化或心理改变的先前数据。我们经历了一个青少年女性神经性厌食症（AN）的情况下，谁否认吃任何东西，但最多20香蕉和少于500毫升矿泉水，每天超过两年。在大量吃香蕉的习惯期间，她显示血清钾（从4.7 mEq/l至6.1 mEq/l）和全血多巴胺（从11 ng/ml至210 ng/ml;正常范围0.5-6.2 ng/ml）增加，以及仅由AN病理学无法解释的明显心境恶劣。当患者在26个月的强迫性和限制性进食香蕉后恢复其他食物摄入时，她的血液数据和心理状态的异常都被纠正为正常。我们的结论是，在这种情况下，强迫和限制的习惯，香蕉摄入导致高钾血症，高多巴胺血症，和心理变化。(C)2006 Elsevier B.

Banana is known as a dopamine-rich and potassium-rich food, however no previous data regarding biochemical or psychological alteration induced by excess intake of banana has been reported. We have experienced an adolescent female case of Anorexia nervosa (AN) who denied eating anything but maximum 20 bananas and less than 500 ml mineral water per day for more than two years. During the period of massive banana eating habit; she showed increase of serum potassium (from 4.7 mEq/l to 6.1 mEq/l) and whole blood dopamine (from 11 ng/ml to 210 ng/ml; normal range 0.5-6.2 ng/ml), and obvious dysthymia that is inexplicable only by the pathology of AN. When the patient resumed other food ingestion after 26 months of obsessive and restricted eating of banana, the abnormalities in her blood data and her psychological state were all corrected toward normal. We conclude that in this case, the obsessive and restricted habit of banana ingestion resulted in hyperkalemia, hyperdopaminemia, and psychological change. (C) 2006 Elsevier B.V. All rights reserved.
