我讀“攝取紅肉和肉類加工品的致癌性”報告 [英文標題] Carcinogenicity of consumption of red and processed meat 出處: The Lancet Oncology, 2015 (Published Online October 26, 2015) Link: http://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2815%2900444-1/abstract 雖然這篇文章來自The Lancet Oncology,說明世界衛生組織(WHO)國際癌症研究機構(International Agency for Research on Cancer, IARC)的一份最新,關於紅肉和加工肉品的致癌性報告,但真正的資料則來自於美國癌症研究機構(The American Institute for Cancer Research, AICR)。 WHO的官方文件(英文版): IARC Monographs evaluate consumption of red meat and processed meat 網址: www.iarc.fr/en/media-centre/pr/2015/pdfs/pr240_E.pdf Lancet Oncology的文章開頭其實說明了紅肉是有其營養價值的~ 紅肉含有高生理價值蛋白質和重要的微量營養素,如B群維生素、鐵質(游離鐵與血基質鐵),和鋅。 Red meat contains high biological-value proteins and important micronutrients such as B vitamins, iron (both free iron and haem iron), and zinc. ... *&^%$#@ ...... 中間省略 一份整理了10份世代研究(Cohort Study)的大腸直腸癌的整合分析(meta-analysis)報告顯示有統計學上明顯的劑量 - 反應關係:
A meta-analysis of colorectal cancer in ten cohort studies reported a statistically significant dose–response relationship, with a 17% increased risk (95% CI 1·05–1·31) per 100 g per day of red meat and an 18% increase (95% CI 1·10–1·28) per 50 g per day of processed meat. 中間關於研究報告的說明、機轉的探討,幾乎是二頁密密麻麻的英文,就不在此贅述了。 重點是文章如此總結: 總體而言,
Overall, the Working Group classified consumption of processed meat as “carcinogenic to humans” (Group 1) on the basis of sufficient evidence for colorectal cancer. Additionally, a positive association with the consumption of processed meat was found for stomach cancer. The Working Group classified consumption of red meat as “probably carcinogenic to humans” (Group 2A). 為做出評斷,工作小組考慮了所有的相關數據,其中包括大量的流行病學資料,顯示
In making this evaluation, the Working Group took into consideration all the relevant data, including the substantial epidemiological data showing a positive association between consumption of red meat and colorectal cancer and the strong mechanistic evidence. Consumption of red meat was also positively associated with pancreatic and with prostate cancer. 趙強的結論: 一、少吃紅肉:
二、不吃加工紅肉:
