如果你最近突然爱上吃这2样东西，说明你的身体确实老了。 1.香菜 研究发现，东亚每五个人就有一个不爱吃香菜。这是因为香菜的"香气"由各种醛类物质组成，但肥皂气 味、臭虫臭味里也带同样的醛类。而有的人体内11号染色体上，一个叫"OR6A2"的基因变异了，嗅觉系 统会把醛类物质，全部判断为难闻的肥皂/臭虫味儿。大脑接收到嗅觉系统传来的强烈判断，就会让这 个人讨厌香菜。 但随着年龄增长，鼻黏膜弹性下降，嗅觉上皮变薄影响了对气味的感知，鼻子里管嗅觉的"筛骨"也会退 化，上面的孔洞变小变少，嗅觉传输会受阻。 2.盐 来源 | 科普中国、好奇博士 结果就是，你的嗅觉功能会慢慢衰弱。你识别到香菜的臭虫味儿，会比年轻时淡很多。于是你就可能突 然"黑转粉"。 要是你发现自己现在越来越爱咸口了，这又是一个口味转折点了。 随着年龄的增长，你味蕾的更新能力会变差，唾液分泌也会跟着减少，而唾液本来是帮助溶解食物里的 味道分子，促进味道分子跟味蕾结合传递味道的。而多项研究发现，"重口"很多时候就表现在吃得咸 上，专业术语叫"味觉补偿"。 ...
