近日，一名原央视主持人在直播间哭诉自己11岁的女儿患上"正食症"的新闻引起了广泛关注。据称，其 女儿由于痴迷"纯净"饮食，完全戒掉了油脂和碳水，只吃水煮菜，蛋白质也吃得非常少，以致免疫力下 降，患流感后心肌损伤，心率一度飙到120次/分钟，最终被确诊为"正食症"并住院治疗。 此事将"正食症"推进了公众视野。什么是"正食症"？为何对"健康饮食"的极致追求，反而导致了危害健 康的结果？"正食症"这种心理行为问题又为何偏偏容易盯上青少年？ "正食症"的真相 在某百科上，"正食症"被解释为一种对健康饮食过度执着的进食障碍，表现为极端限制食物种类、追 求"纯净"饮食，最终导致严重营养不良和脏器损伤。它并非真正的健康饮食行为，而是一种需要干预的 心理疾病。 然而，在医学的严谨框架内，"正食症"却并非一个独立的诊断标签。 林溪的治疗初期异常艰难。面对要求增加进食的医疗方案，她内心抗拒，但在医生的监管下，她最终还 是被动配合了。随着体重逐步恢复，她的精神状态开始改善，认知功能也从营养不良的"迷雾"中逐渐清 晰。 林溪的医生解释说，在严重营养不良状态下，大脑功能会受损，患者往往无法理性认识到自己行为的病 态。当身体得到修复，大 ...
