Abstract
The urinary excretion of (an) odorous substance(s) after eating asparagus is not an inborn error of metabolism as has been supposed. The detection of the odour constitutes a specific smell hypersensitivity. Those who could smell the odour in their own urine could all smell it in the urine of anyone who had eaten asparagus, whether or not that person was able to smell it himself. Thresholds for detecting the odour appeared to be bimodal in distribution, with 10% of 307 subjects tested able to smell it at high dilutions, suggesting a genetically determined specific hypersensitivity.
摘要
食用芦笋后有气味物质的尿液排泄并非如人们所认为的那样是一种先天性代谢缺陷。气味的检测构成一种特定的嗅觉超敏反应。那些能在自己尿液中闻到气味的人，都能在食用过芦笋的任何人的尿液中闻到这种气味，无论那个人自己是否能闻到。检测该气味的阈值分布似乎呈双峰状，在307名受试对象中，有10%的人在高稀释度下就能闻到，这表明存在一种由基因决定的特定超敏反应。
