食物渴望

食物渴望(food craving)是一种想吃特定食物的强烈欲望,与饥饿感不同。[1] 而将非食品当作食物的渴望称为异食癖[2]

食物渴望不一定是病态的[3],这种渴望并不总是对美味的东西。它也可能是由营养缺乏、无聊或单调的饮食引起的[3]。食物渴望现象的成因可能源自营养素缺乏以及摄取该营养素的驱动力;其次是心理制约,特定的线索或场景诱发个人想吃以往经验中曾与该线索或场景连结的食物。[4]

食物渴望非常普遍,1990年代在加拿大进行的研究发现,97% 的大学女性和 68% 的大学男性表示有过对食物的渴望[5]。在对食物渴望的研究中,巧克力几乎总是排在人们表示渴望的食物之首;[5][6]这种渴望被称为巧克力瘾

虽然某些食物能够让人“渴望”,但食物是否会像药物和酒精一样成瘾还不太清楚。与渴望不同,食物成瘾更进一步,不仅包括强烈的渴望,而且还表现出对饮食行为的失控和反复过量食用食物,尤其是美味的食物[7]

而所谓的食物成瘾是否存在,或者一些难以控制自己的食物摄入量的人是否可以被视为食物成瘾者,目前尚无共识。它仍然是一个备受争议的领域。一些研究人员认为,药物和酒精成瘾的定义特征在食物成瘾中并不存在,而其他人则认为它们具有与大脑神经系统变化相关的相似特征[8][9][10]

食物渴望与高BMI以及可能导致体重增加的行为相关,包括增加零食、饮食不节制、以及暴食/贪食症[11][12]
