[最後編寫日期：2013/09/02]
文 / 劉語潔 (營養師)
聞「癌」色變！惡性腫瘤為民國101年國人十大死因的第一名，蟬聯死因榜首31年
。其中，結直腸癌為癌症死因第三名，其發生率連續5年蟬聯第一名，約每1小時42分26
秒就有一人診斷為大腸直腸癌。但是，也別以為大腸癌是老年人的專利。據國健局二月
的檢驗結果顯示，20到40歲的上班族群中，每四人就有1人有腸瘜肉，腸瘜肉為大腸癌
的前兆，顯示大腸癌正逐漸年輕化。
大腸癌年輕化的主因為何? 觀察年輕族群的生活型態，常態性不健康外食、久坐、
壓力為影響腸胃健康的三大主因。首先，長期高油低纖的外食習慣，接觸燒烤油炸類食
物，減緩腸胃蠕動，會導致排便不順，腸道內毒素累積，進而造成腸胃細胞病變。以下
更近一步的分析出二點：
1. 動物性飲食燒烤會產生致癌物：主要是肉類中有兩種胺基酸：左旋-苯基丙胺酸
(L-phenylalamine)與肌胺酸(Creatine)經過高溫油炸燒烤後會產生致癌物

For those parents who are more interested in science, roundup targets the

roundup should be safe if accidentally spilled on your skin or mouth, as

国内空气质量之差已是众所周知，然而：
1.民众对此的认识程度不一
国内长期居住者尤其是没有出过国，对居住环境习以为常后很多把smog当作正常现
象(很多人甚至连什么是smog都不知道)，这个道理跟自己的小孩长得多快自己有时
注意不到，别人反而看得更清楚无异。海归一般都在空气清新的发达国家居住过，
回去后(有些从飞机下降起)就下意识地发觉空气的变化，不免多几句牢骚。然而这
种抱怨很容易被国内民众嘲笑。讽刺的是最后笑不出的人里大部分还是国内的人，这
点见第二点。
2.民众对空气差带来的危害性普遍认知不足
空气污染成份大致有这几样：氮氧化物(NOx)，一氧化碳(CO)，不完全燃烧形成的碳
氢化合物(UHC or unburnt hydrocarbon)，碳颗粒(soot)，氧化硫(SOx)。至于灰尘
(自然现象哪里都有)，二氧化碳对身体没什么危害。直接致癌的是碳氢化合物的含
