    粗粮养成否?

    人说,粗粮有益健康。
    后来,我听一个年长的邻居说(他牛是时在读山东大学),南方人到北方读几年书下来,胃多半会被北方的粗粮折腾完了。
    再后来,我的胃倒没有因为粗粮受过太大伤,其实更伤胃的是不规律饮食(主要是不按点吃早饭给饿的)。
    那粗粮,粗粮有益健康吗?我不知道,但我支持这个观点,不过我却对粗粮提不起太多兴趣。
    前段时间听到另一个粗粮有益健康的故事。相当另类的支持做法。不久前,听到有一个朋友买了一部二手的Lexus ES300,9年车龄,17万英里。又听说,原车主这17万英里跑着最普通的汽油(87号)。没有什么特殊理由,不愿意加贵的“好油”(91号)。我又想起另一个朋友,去年买的新帕萨特,加了大半年的普通汽油(87号),直到去做保养的时候才知道,应该加最贵的那种“好油”(91号)。我其实不应该用“好”和“普通”来区分,因为它们价差的原因并不是因为好坏,而是辛烷值(Octane)不同罢了(http://en.wikipedia.org/wiki/Octane_rating)。
    粗粮是否有益健康?我认为还是应该把问题约束成“粗粮是否有益于你的健康?”。因为具体问题还是应该具体分析的。于人,于车,我想都是类似的。对于人来说,医嘱或许权威得多;对于汽车,现成的手册应该是具有最高指导价值的。只是,满目的英文,厚厚的手册,让多数人望而却步罢了。
