根據(jù)發(fā)表于《英國癌癥雜志》（BJC）上的一項(xiàng)研究,，攝入過多加工過的肉食品可能增加胰腺癌風(fēng)險(xiǎn)。
這項(xiàng)研究由瑞士癌癥基金會和斯德哥爾摩卡羅林斯卡醫(yī)學(xué)院資助,。研究發(fā)現(xiàn),，與那些不吃肉的人相比，每天攝入50克,、100克,、150克加工過的肉食品（相當(dāng)于一根香腸或2片培根）的人患胰腺癌的風(fēng)險(xiǎn)分別增加19%、38%,、57%,。
每天攝入100克加工過的肉食品比每天攝入50克加工過的肉食品的人患胰腺癌的風(fēng)險(xiǎn)增加19%,。
紅肉增加男性而非女性患胰腺癌風(fēng)險(xiǎn)的證據(jù)尚無定論。結(jié)果顯示,，與不吃肉的人相比,，每天攝入120克加工過的肉食品的男性患胰腺癌的風(fēng)險(xiǎn)增加29%。
攝食加工過的肉食品使患胰腺癌的風(fēng)險(xiǎn)增加19%,，這看似可能很高--但它是在患胰腺癌幾率相對來說很小的基礎(chǔ)上的一個(gè)增加,。在英國，在整個(gè)一生中男性和女性患胰腺癌的幾率分別為1/77和1/79,。
相對而言,，吸煙使患胰腺癌風(fēng)險(xiǎn)增加74%。
研究人員分析了涉及超過6000名胰腺癌患者的11項(xiàng)研究數(shù)據(jù),。
卡羅林斯卡醫(yī)學(xué)院副教授Susanna Larsson說："胰腺癌患者存活率較差,。所以早期診斷很重要，了解什么因素能增加胰腺癌風(fēng)險(xiǎn)也同樣重要,。"
"如果飲食不影響患胰腺癌風(fēng)險(xiǎn),，那么這可能會有益于公眾的健康意識，從源頭上幫助減少患胰腺癌疾病的患者數(shù)目,。"
2008年,，在英國大約有8090人被診斷患胰腺癌，占到了所有癌癥病例的3%--大約7780人死于胰腺癌,。
英國癌癥研究中心信息主任Sara Hiom說："肉類是否是一個(gè)確定的胰腺癌風(fēng)險(xiǎn)因子尚未最終定論,，需要開展更大規(guī)模的研究來證實(shí)這一點(diǎn)。但這項(xiàng)新的分析表明,，加工的肉類在胰腺癌疾病中可能扮演了一個(gè)角色,。"
"我們知道，在各種生活方式因素中,，吸煙顯著增加了患胰腺癌的風(fēng)險(xiǎn),。戒煙是降低自身患各種癌癥及其他疾病最好的方式。"（生物谷bioon.com）

Red and processed meat consumption and risk of pancreatic cancer: meta-analysis of prospective studies
S C Larsson and A Wolk
Abstract： background: Whether red and processed meat consumption is a risk factor for pancreatic cancer remains unclear. We conducted a meta-analysis to summarise the evidence from prospective studies of red and processed meat consumption and pancreatic cancer risk. methods: Relevant studies were identified by searching PubMed and EMBASE databases through November 2011. Study-specific results were pooled using a random-effects model. results: Eleven prospective studies, with 6643 pancreatic cancer cases, were included in the meta-analysis. An increase in red meat consumption of 120 g per day was associated with an overall relative risk (RR) of 1.13 (95% confidence interval (CI)=0.93–1.39; Pheterogeneity<0.001). Red meat consumption was positively associated with pancreatic cancer risk in men (RR=1.29; 95% CI=1.08–1.53; Pheterogeneity=0.28; five studies), but not in women (RR=0.93; 95% CI=0.74–1.16;Pheterogeneity=0.21; six studies). The RR of pancreatic cancer for a 50 g per day increase in processed meat consumption was 1.19 (95% CI=1.04–1.36; Pheterogeneity=0.46). conclusion: Findings from this meta-analysis indicate that processed meat consumption is positively associated with pancreatic cancer risk. Red meat consumption was associated with an increased risk of pancreatic cancer in men. Further prospective studies are needed to confirm these findings.
